Analyticity, Balance and Non-Admissibility of in Stoic Logic
Susanne Bobzien Analyticity, Balance and Roy Dyckhoff Non-admissibility of Cut in Stoic Logic Abstract. This paper shows that, for the Hertz–Gentzen Systems of 1933 (without Thin- ning), extended by a classical rule T 1 (from the Stoics) and using certain axioms (also from the Stoics), all derivations are analytic: every cut formula occurs as a subformula in the cut’s conclusion. Since the Stoic cut rules are instances of Gentzen’s Cut rule of 1933, from this we infer the decidability of the propositional logic of the Stoics. We infer the correctness for this logic of a “relevance criterion” and of two “balance criteria”, and hence (in contrast to one of Gentzen’s 1933 results) that a particular derivable sequent has no derivation that is “normal” in the sense that the first premiss of each cut is cut-free. We also infer that Cut is not admissible in the Stoic system, based on the standard Stoic axioms, the T 1 rule and the instances of Cut with just two antecedent formulae in the first premiss. Keywords: Sequent, Analyticity, Stoic logic, Proof theory, Decidability, Relevance, Balance, Cut-admissibility. Introduction and Overview There is dispute and uncertainty about the exact details of much of the logic of the Stoics. The primary sources are fragmentary and the secondary sources fail to provide a coherent account. We ignore the Stoics’ modal logic and consider only their propositional logic, which may be regarded as a frag- ment of what we now call classical propositional logic. It is a substructural logic and a relevant logic, with that term broadly conceived: the rule of Thinning is neither present nor admissible and an atom-sharing property, as in [11], i.e. -

INTRODUCTION The College of All Souls of the Faithful Departed, of Oxford – known as All Souls College – was founded by Henry VI and Henry Chichele (Archbishop of Canterbury) in 1438. Today the College is primarily an academic research institution with particular strengths in the Humanities, Mathematics, Social and Natural Sciences and an outstanding library. It also has strong ties to public life. Although the Warden and Fellows of the College are involved in teaching and supervision of research in the University, there are no undergraduate members. On 31 July 2014 there were seventy-seven Fellows of All Souls, twenty-nine Emeritus (i.e. retired academic) and seven Honorary Fellows, many of whose continuing research the College was actively supporting. -
Search for New Physics in Dijet Resonant Signatures and Recent Results from Run 2 with the CMS Experiment
138 Proceedings of the LHCP2015 Conference, St. Petersburg, Russia, August 31 - September 5, 2015 Editors: V.T. Kim and D.E. Sosnov Search for new physics in dijet resonant signatures and recent results from Run 2 with the CMS experiment GIULIA D’IMPERIO Universit`aLa Sapienza and INFN Roma On behalf of the CMS Collaboration Abstract. A search for narrow resonances in proton-proton collisions at a center-of-mass energy of √s = 13 TeV is presented. The dijet invariant mass distribution of the two leading jets is measured with the CMS detector using early data from Run 2 of the Large Hadron Collider. The dataset presented here was collected in July 2015 and corresponds to an integrated luminosity of 42 1 pb− . The highest observed dijet mass is 5.4 TeV. The spectrum is well described by a smooth parameterization and no evidence for new particle production is observed. Upper limits at a 95% confidence level are set on the cross section of narrow resonances with masses above 1.3 TeV. When interpreted in the context of specific models the limits exclude: string resonances with masses below 5.1 TeV; scalar diquarks below 2.7 TeV; axigluons and colorons below 2.7 TeV; excited quarks below 2.7 TeV; and color octet scalars below 2.3 TeV. Introduction Deep inelastic proton-proton (pp) collisions often produce two or more energetic jets when the constituent partons are scattered with large transverse momenta (pT ). The invariant mass of the two jets with the largest pT in the event (the dijet) has a spectrum that is predicted by quantum chromodynamics (QCD) to fall steeply and smoothly with increasing dijet mass (m jj) [1]. -

Submitted in fulfilment of the requirements of the Degree of Doctor of Education (Ed.D.) School of Education, College of Social Sciences University of Glasgow April, 2019 Abstract ‘Class’ has become increasingly invisible in contemporary society, with teachers reluctant to discuss or acknowledge it (Reay, 2006; Hall and Jones, 2013). This can lead to inequality as the education system continues to disadvantage working-class children while advantaging their middle-class peers. In this study, I focus on two aspects of this problem. First is the impact on education due to the perpetuation of class-based inequality and, secondly, the (in)ability of teachers to recognise and/or address this inequality within the system. -

Disentangling Heavy Flavor at Colliders
MIT-CTP/4880 Disentangling Heavy Flavor at Colliders Philip Ilten,1, ∗ Nicholas L. Rodd,2, y Jesse Thaler,2, z and Mike Williams1, x 1Laboratory for Nuclear Science, Massachusetts Institute of Technology, Cambridge, MA 02139, U.S.A. 2Center for Theoretical Physics, Massachusetts Institute of Technology, Cambridge, MA 02139, U.S.A. We propose two new analysis strategies for studying charm and beauty quarks at colliders. The first strategy is aimed at testing the kinematics of heavy-flavor quarks within an identified jet. Here, we use the SoftDrop jet-declustering algorithm to identify two subjets within a large-radius jet, using subjet flavor tagging to test the heavy-quark splitting functions of QCD. For subjets containing a J= or Υ, this declustering technique can also help probe the mechanism for quarkonium production. The second strategy is aimed at isolating heavy-flavor production from gluon splitting. Here, we introduce a new FlavorCone algorithm, which smoothly interpolates from well-separated heavy- quark jets to the gluon-splitting regime where jets overlap. Because of its excellent ability to identify charm and beauty hadrons, the LHCb detector is ideally suited to pursue these strategies, though similar measurements should also be possible at ATLAS and CMS. Together, these SoftDrop and FlavorCone studies should clarify a number of aspects of heavy-flavor physics at colliders, and provide crucial information needed to improve heavy-flavor modeling in parton-shower generators. I. INTRODUCTION The production of charm and beauty quarks at the Large Hadron Collider (LHC) is studied both as a fun- damental probe of Standard Model (SM) phenomenology, and as an important component of searches for physics beyond the SM.
