Between the LHC and B Factories (Probing Beyond the Standard Model with flavor) Proposal for a Workshop at the Aspen Center for Physics, Summer 2007 Y. Grossman, Z. Ligeti, G. Perez, and M. Schmaltz Between the LHC and B factories (probing beyond the standard model with flavor) Flavor physics has been the focus of intense experimental and theoretical activity over the past several years. The B factories and hadron machines have provided a lot of data, basically in agreement with the standard model of flavor. This success, however, is puzzling when confronted with the hierarchy problem. Naturalness considerations of the standard model Higgs sector strongly motivate new physics at the TeV scale. Flavor physics, on the other hand, put severe bounds on such new physics. It is clear that any new physics at the TeV scale must have a special flavor structure. The LHC is scheduled to turn on only a few months after this workshop. For the first time we will be able to directly search for new particles at TeV energies. In addition, the machine will also provide a wealth of new data on third generation flavor physics, as ATLAS and CMS will record millions of reconstructed top quark decays and LHCb, ATLAS and CMS will accumulate unparalleled samples of b hadron decays. Thus, a major challenge and opportunity facing the theory community after the LHC startup will be to understand the flavor structure of the new physics at the TeV scale. To prepare for this challenge, we propose a workshop which focuses on new physics at the TeV scale and beyond, with an emphasis on issues of flavor. We envision participation by physicist interested in the physics of K, D, and mainly B mesons, flavor violation in leptons, top physics, and by physicists interested in models of electroweak symmetry breaking, TeV scale extensions, and models of flavor. There is still a lot to understand about flavor, and we believe that much progress can be made by seeding collaborations between these different communities in the informal atmosphere of an Aspen Center for Physics workshop. Dates of the workshop We propose a five week workshop. Since some of us have conflicting commitments during the month of June and in the second half of August, our most preferred starting date would be July 1st, 8th or 15th. Participants The following leaders in their respective fields have been contacted by us and have indi- cated their interest in attending our workshop: Cristian Bauer, Andrzej Buras, Adam Falk, Howard Haber, Lawrence Hall, Gudrun Hiller, Alex Kagan, David B.

Ferrara - CERN, 2016 3 In the early 1970s I was a staff member at the Frascati National Laboratories of CNEN (then the National Nuclear Energy Agency), and with my colleagues Aurelio Grillo and Giorgio Parisi we were investigating, under the leadership of Raoul Gatto (later Professor at the University of Geneva) the consequences of the application of “Conformal Invariance” to Quantum Field Theory (QFT), stimulated by the ongoing Experiments at SLAC where an unexpected Bjorken Scaling was observed in inclusive electron- proton Cross sections, which was suggesting a larger space-time symmetry in processes dominated by short distance physics. In parallel with Alexander Polyakov, at the time in the Soviet Union, we formulated in those days Conformal invariant Operator Product Expansions (OPE) and proposed the “Conformal Bootstrap” as a non-perturbative approach to QFT. S. Ferrara - CERN, 2016 4 Conformal Invariance, OPEs and Conformal Bootstrap has become again a fashionable subject in recent times, because of the introduction of efficient new methods to solve the “Bootstrap Equations” (Riccardo Rattazzi, Slava Rychkov, Erik Tonni, Alessandro Vichi), and mostly because of their role in the AdS/CFT correspondence. The latter, pioneered by Juan Maldacena, Edward Witten, Steve Gubser, Igor Klebanov and Polyakov, can be regarded, to some extent, as one of the great legacies of higher dimensional Supergravity.

    CERN-TH/98-354 hep-ph/9811291 Quantum Gravity and Extra Dimensions at High-Energy Colliders Gian F. Giudice, Riccardo Rattazzi, and James D. Wells Theory Division, CERN CH-1211 Geneva 23, Switzerland Abstract Recently it has been pointed out that the characteristic quantum-gravity scale could be as low as the weak scale in theories with gravity propagating in higher dimensions. The observed smallness of Newton’s constant is a consequence of the large compactified volume of the extra dimensions. We investigate the consequences of this supposition for high-energy collider experiments. We do this by first compactifying the higher dimen- sional theory and constructing a 3 + 1-dimensional low-energy effective field theory of the graviton Kaluza-Klein excitations and their interactions with ordinary matter. We then consider graviton production processes, and select γ+ E and jet+ E signatures 6 6 for careful study. We find that both a 1 TeV e+e− collider and the CERN LHC will be able to reliably and perturbatively probe the fundamental gravity scale up to several arXiv:hep-ph/9811291v2 13 Mar 2000 TeV, with the precise value depending on the number of extra dimensions. Similarly, searches at LEP2 and the Tevatron are able to probe this scale up to approximately 1 TeV. We also discuss virtual graviton exchange, which induces local dimension-eight operators associated with the square of the energy-momentum tensor. We estimate the size of such operators and study their effects on ff¯ γγ observables. → CERN-TH/98-354 November 1998 Contents 1 Introduction 1 2 The Kaluza-Klein Excitations of the Graviton 7 3 Feynman Rules 14 4 Graviton Production Processes 18 5 Virtual Graviton Exchange 21 6 Graviton Production and Collider Experiments 24 6.1 e+e− andMuonColliders............................

This scenario ele- gantly evades the supersymmetric flavor problem since soft masses, like the anomaly, are not directly sensitive to ultraviolet physics. However, its minimal incarnation fails by predicting tachyonic sleptons. We study the conditions for decoupling of heavy threshold effects and how these conditions are evaded. We use these results to build a realistic class of models where the non-decoupling effects of ultra-heavy vectorlike matter fields eliminate the tachyons. These models have a flavor invariant superspectrum similar to that of gauge mediated models. They, however, differ in several aspects: the gaugino masses are not unified, the colored sparticles are not much heavier than the others, the µ problem is less severe and the gravitino mass is well above the weak scale, m3=2 & 10 TeV. We also show that in models where an R-symmetry can be gauged, the associated D-term gives rise to soft terms that are similarly insensitive to the ultraviolet.

  • Dark Matter and Collider Phenomenology of Non-Universal Gaugino Masses

Signals of dark matter including direct and indirect detection are investigated at depth in various supersymmetric frameworks. The parameter space of deflected mirage mediation, in which the soft terms receive contributions from the three main supersymmetry breaking mediation mechanisms, is investigated with emphasis on the neutralino sector and dark matter signals. The potential for non-universal gaugino masses to explain the recent CDMS II data is studied and possible implications for indirect dark matter detection experiments and LHC signatures are considered. Collider implications of non- universalities in the gaugino sector are examined with attention paid to specific signatures which are targeted to track the non-universalities. Further, the complementarity of dark matter and collider measurements is discussed with emphasis on breaking model degeneracies which may arise in LHC data.

    USTC-ICTS-18-13 Positivity bounds on vector boson scattering at the LHC Cen Zhang Institute of High Energy Physics, Chinese Academy of Sciences, Beijing 100049, China Shuang-Yong Zhou Interdisciplinary Center for Theoretical Study, University of Science and Technology of China, Hefei, Anhui 230026, China Weak vector boson scattering (VBS) is a sensitive probe of new physics effects in the electroweak symmetry breaking. Currently, experimental results at the LHC are interpreted in the effective field theory approach, where possible deviations from the Standard Model in the quartic-gauge-boson couplings are often described by 18 dimension-8 operators. By assuming that a UV completion exists, we derive a new set of theoretical constraints on the coefficients of these operators, i.e. certain combinations of coefficients must be positive. These constraints imply that the current effective approach to VBS has a large redundancy: only about 2% of the full parameter space leads to a UV completion. By excluding the remaining unphysical region of the parameter space, these constraints provide guidance for future VBS studies and measurements.

There are two different sides from which to regard the legacy of LEP/SLC, and forming what is also known as the LEP paradox [1]. From one side it is an impressive triumph of human endeavour: the Standard Model (SM) is a complete theory of fundamental processes successfully tested at the per-mille precision. That means that small quantum corrections to the Born approximation are essential in the comparison between theory and experiment. However, when regarded from the other side, this great success becomes a huge conceptual bafflement, because the hierarchy problem, which inspired theoretical speculations for the last three decades, suggested that the SM should be overthrown right at the weak scale. That did not happen, so we must now understand why. I will discuss the paradoxical LEP/SLC legacy in the first part of my talk.

  • Brane-To-Brane Mediation of Supersymmetry Breaking in Presence of D-Type Breaking 1

Introduction As it is well known, supersymmetry is a very attractive option for physics beyond the Standard Model (SM). While it has not been discovered at LEP and the Tevatron, it will still be extensively looked for at the LHC, and many remain hopeful that it will be seen there. An important feature of supersymmetry is that it guarantees the absence of quadratic divergence in the renormalization of scalar masses, in the case of interest the Higgs mass. This property holds even if supersymmetry is broken softly, that is by operators of dimension two or three. The minimal extension of the SM into such a theory is called the minimal supersymmetric standard model (MSSM). It contains renormalizable supersymmetric interactions as well as a set of super- renormalizable, supersymmetry-breaking interactions dubbed the soft masses: L L 2 u u d d e d u d = kin + d θ yijQiUjH + yijQiDjH + yijLiEjH + μH H (1) 2 ∗ a a a u u u d ··· +mijqi qj + m1/2λ λ + yijAuqiujh + Bμh h + , 2 a where mij are scalar soft masses squared, m1/2 gaugino masses and A trilinear scalar terms. The dots denote similar terms. The value of these soft masses are very constrained by experiment. One constraint comes from the fact that supersymmetry has not yet been discovered, which requires the superpartners to be somewhat heavy.

Contribution to the volume \From My Vast Repertoire" { The Legacy of Guido Altarelli. 1 A Master and a Friend Honour a king in his own land; honour a wise man everywhere. | Tibetan proverb [1] Guido Altarelli was an extraordinary theoretical physicist. Not only was Guido one of the heroes of the Standard Model, but he incarnated the very essence of that theory: a perfect synthesis of pure elegance and brilliance. With his unique charisma, he had a great influence on CERN and contributed much in promoting the role of theoretical physics in the life of the laboratory. With the right mixture of vision, authority, and practical common sense, he led the Theory Division from 2000 to 2004. I have always admired Guido for his brilliance, humour, knowledge, leadership, and intellectual integrity. I learned much from his qualities and his example is a precious legacy for me and for all of his colleagues. Guido had a very pragmatic attitude towards scientific theories. He was not attracted arXiv:1710.07663v1 [physics.hist-ph] 18 Oct 2017 by elaborate mathematical constructions, but wanted to understand the essence behind the formalism and get straight to the concept.

In fact, it allows for accommodating, with no further parameter tuning, large values of Bµ and of the other Higgs-sector soft masses, as predicted in models where both µ and Bµ are generated at one-loop order. This class of models, called Lopsided Gauge Mediation, offers an interesting alternative to conventional gauge mediation and is characterized by a strikingly different phenomenology, with light higgsinos, very large Higgs pseudoscalar mass, and moderately light sleptons. We discuss general parametric relations involving the fine-tuning of the model and various observables such as the chargino mass and the value of tan β. We build an explicit model and we study the constraints coming from LEP and Tevatron. We show that in spite of new interactions between the Higgs and the messenger superfields, the theory can remain perturbative up to very large scales, thus retaining gauge coupling unification.
