However when sparticles are produced the signatures of their production will to a significant degree depend on their hierarchical mass patterns. Here we investigate hierarchical mass patterns for the four lightest sparticles within one of the leading candidate theories - the SUGRA model. Specifically we analyze the hierarchies for the four lightest sparticles for the mSUGRA as well as for a general class of super- gravity unified models including nonuniversalities in the soft breaking sector. It is shown that out of nearly 104 possibilities of sparticle mass hierarchies, only a small number survives the rigorous constraints of radiative electroweak symmetry break- ing, relic density and other experimental constraints. The signature space of these mass patterns at the LHC is investigated using a large set of final states including multi-leptonic states, hadronically decaying τs, tagged b jets and other hadronic jets.

  • Detecting Hidden Sector Dark Matter at HL-LHC and HE-LHC Via Long-Lived Stau Decays
    PHYSICAL REVIEW D 99, 055037 (2019) Detecting hidden sector dark matter at HL-LHC and HE-LHC via long-lived stau decays † Amin Aboubrahim* and Pran Nath Department of Physics, Northeastern University, Boston, Massachusetts 02115-5000, USA (Received 14 February 2019; published 27 March 2019) We investigate a class of models where the supergravity model with the standard model gauge group is ð1Þ extended by a hidden sector U X gauge group and where the lightest supersymmetric particle is the neutralino in the hidden sector. We investigate this possibility in a class of models where the stau is the lightest supersymmetric particle in the minimal supersymmetric standard model sector and the next-to- ð1Þ lightest supersymmetric particle of the U X-extended supergravity model. In this case the stau will decay into the neutralino of the hidden sector. For the case when the mass gap between the stau and the hidden ð1Þ ð1Þ sector neutralino is small and the mixing between the U Y and U X is also small, the stau can decay into the hidden sector neutralino and a tau which may be reconstructed as a displaced track coming from a high-pT track of the charged stau. Simulations for this possibility are carried out for HL-LHC and HE-LHC. The discovery of such a displaced track from a stau will indicate the presence of hidden sector dark matter.

  • AUB Physicist Ali Chamseddine Among TWAS Awardees
    AUB Physicist Ali Chamseddine among TWAS awardees Friday October 30, 2009 The winners of the 2008 Academy of Sciences for the Developing World (TWAS) prizes in agricultural sciences, biology, chemistry, earth sciences, engineering sciences, mathematics, medical sciences, and physics were announced last month at the general meeting of TWAS held last month in Durban, South Africa. All the winners are from developing countries. The physics prize was won by AUB's Ali Hani Chamseddine and Predhiman Krishan Kaw, from India. Chamseddine was honored for his fundamental contributions to supergravity and noncommutative geometry. Born in Lebanon in 1953, Professor Chamseddine studied physics at the Lebanese University and was awarded a full scholarship to pursue graduate studies at Imperial College, London University, where he earned his PhD in 1976. He then did his postdoctoral study at the International Center for Theoretical Physics in Trieste, Italy before joining AUB as an assistant professor in 1977. Because of the war in Lebanon, in 1979 Chamseddine left Lebanon to work at the European organization for Nuclear Research in Switzerland; later, at Northeastern University in Boston, he produced ground- breaking research on particles physics with Richard Arnowitt and Pran Nath. Chamseddine returned to AUB in 1985, but then left again to work at the Swiss Federal Institute of Technology and at the University of Zurich. Returning to AUB in 1998, he became the founding director of the newly-established Center for Advanced Mathematical Sciences. Under his leadership, CAMS became the leading institute of mathematical sciences in the Middle East. He remained in this position until 2003 and now teaches in AUB's Physics Department.

This new research, published in the July issue of Physical Review Letters, confirms that it can. The results are of importance because the discovery of this particle would provide a clue to the nature of physics beyond the Standard Model and a possible link with string theory. “It is exciting to know that the discovery of the proposed particle at colliders is indeed possible,” said Pran Nath, Matthews Distinguished University Professor of Physics at Northeastern University. “Physicists are always looking for what is next, what will lie beyond the Standard Model. These findings point us in the direction of those answers.” Because of its extreme narrowness, the Stueckelberg Z prime particle resembles the J/Psi (charmonium) particle, whose simultaneous discovery in 1974 by Burton Richter and Samuel Ting earned them the 1976 Nobel Prize in Physics.

An analysis of supersymmetric contributions to Rb in supergravity grand unification with nonuniversal boundary conditions on soft supersymmetry breaking in the scalar sector is given. Effects on Rb of Planck scale corrections on gaugino masses are also analyzed. It is found that there exist regions of the parameter space where positive corrections to Rb of size ;1s can be gotten. The region of the parameter space where enhancement of Rb occurs is identified. Predictions of sparticle masses for the maximal Rb case are given.

  • Supersymmetry at a 28 Tev Hadron Collider: HE-LHC
    Supersymmetry at a 28 TeV hadron collider: HE-LHC Amin Aboubrahim∗ and Pran Nathy Department of Physics, Northeastern University, Boston, MA 02115-5000, USA June 20, 2018 Abstract: The discovery of the Higgs boson at 125 GeV indicates that the scale of weak scale supersymmetry is higher than what was perceived∼ in the pre-Higgs boson discovery era and lies in the several TeV region. This makes the discovery of supersymmetry more challenging and argues for hadron colliders beyond LHC at ps = 14 TeV. The Future Circular Collider (FCC) study at CERN is considering a 100 TeV collider to be installed in a 100 km tunnel in the Lake Geneva basin. Another 100 km collider being considered in China is the Super proton-proton Collider (SppC). A third possibility recently proposed is the High-Energy LHC (HE-LHC) which would use the existing CERN tunnel but achieve a center-of-mass energy of 28 TeV by using FCC magnet technology at significantly higher luminosity than at the High Luminosity LHC (HL-LHC). In this work we investigate the potential of HE-LHC for the discovery of supersymmetry. We study a class of supergravity unified models under the Higgs boson mass and the dark matter relic density constraints and compare the analysis with the potential reach of the HL-LHC. A set of benchmarks are presented which are beyond the discovery potential of HL-LHC but are discoverable at HE-LHC. For comparison, we study model points at HE-LHC which are also discoverable at HL-LHC. For these model points, it is found that their discovery would require a HL-LHC run between 5-8 years while the same parameter points can be discovered in a period of few weeks to 1:5 yr at HE-LHC running at its optimal luminosity of 2:5 1035 cm−2 s−1.

  • SUSY DARK MATTER Achille Corsetti and Pran Nath Department Of
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by CERN Document Server SUSY DARK MATTER Achille Corsetti and Pran Nath Department of Physics, Northeastern University, Boston, MA 02115-5005, USA Abstract Several new effects have been investigated in recent analyses of supersymmetric dark matter. These include the effects of the uncertainties of wimp velocity dis- tributions, of the uncertainties of quark densities, of large CP violating phases, of nonuniversalities of the soft SUSY breaking parameters at the unification scale and of coannihilation on supersymmetric dark matter. We review here some of these with emphasis on the effects of nonuniversalities of the gaugino masses at the unification scale on the neutralino-proton cross-section from scalar interactions. The review encompasses several models where gaugino mass nonuniversalities occur including SUGRA models and D brane models. One finds that gaugino mass nonuniversalities can increase the scalar cross-sections by as much as a factor of 10 and also signifi- cantly extend the allowed range of the neutralino mass consistent with constraints up to about 500 GeV. These results have important implications for the search for supersymmetric dark matter. 1 INTRODUCTION Over the recent past there has been considerable experimental activity in the di- rect detection of dark matter 1, 2) and further progress is expected in the ongoing experiments 1, 2, 3) and new experiments that may come online in the future 4). At the same time there have been several theoretical developments which have shed light on the ambiguities and possible corrections that might be associated with the predictions on supersymmetric dark matter.
