Approximate Symmetries and Gravity
Sylvain Fichet, Prashant Saraswat
There are strong reasons to believe that global symmetries of quantum theories cannot be exact in the presence of gravity. While this has been argued at the qualitative level, esta…
Mass Hierarchy and Vacuum Energy
Clifford Cheung, Prashant Saraswat
A hierarchically small weak scale does not generally coincide with enhanced symmetry, but it may still be exceptional with respect to vacuum energy. By analyzing the classical vacu…
The Weak Gravity Conjecture and Effective Field Theory
Prashant Saraswat
The Weak Gravity Conjecture (WGC) is a proposed constraint on theories with gauge fields and gravity, requiring the existence of light charged particles and/or imposing an upper bo…
Physics at a 100 TeV pp collider: beyond the Standard Model phenomena
T. Golling, M. Hance, P. Harris +111
This report summarises the physics opportunities in the search and study of physics beyond the Standard Model at a 100 TeV pp collider.
Towards a No-Lose Theorem for Naturalness
David Curtin, Prashant Saraswat
We derive a phenomenological no-lose theorem for naturalness up to the TeV scale, which applies when quantum corrections to the Higgs mass from top quarks are canceled by perturbat…
A New Probe of Dark Sector Dynamics at the LHC
Arpit Gupta, Reinard Primulando, Prashant Saraswat
We propose a LHC search for dilepton resonances in association with large missing energy as a generic probe of TeV dark sector models. Such resonances can occur if the dark sector…
Natural Inflation and Quantum Gravity
Anton de la Fuente, Prashant Saraswat, Raman Sundrum
Cosmic Inflation provides an attractive framework for understanding the early universe and the cosmic microwave background. It can readily involve energies close to the scale at wh…
Identifying boosted new physics with non-isolated leptons
Christopher Brust, Petar Maksimovic, Alice Sady +3
We demonstrate the utility of leptons which fail standard isolation criteria in searches for new physics at the LHC. Such leptons can arise in any event containing a highly boosted…
Supersymmetric Crevices: Missing Signatures of RPV at the LHC
Peter Graham, Surjeet Rajendran, Prashant Saraswat
Supersymmetry is under pressure from LHC searches requiring colored superpartners to be heavy. We demonstrate R-parity violating spectra for which the dominant signatures are not c…
Gravity waves from cosmic bubble collisions
Michael P. Salem, Prashant Saraswat, Edgar Shaghoulian
Our local Hubble volume might be contained within a bubble that nucleated in a false vacuum with only two large spatial dimensions. We study bubble collisions in this scenario and…
Excess Higgs Production in Neutralino Decays
Kiel Howe, Prashant Saraswat
The ATLAS and CMS experiments have recently claimed discovery of a Higgs boson-like particle at ~5 sigma confidence and are beginning to test the Standard Model predictions for its…
Displaced Supersymmetry
Peter W. Graham, David E. Kaplan, Surjeet Rajendran +1
The apparent absence of light superpartners at the LHC strongly constrains the viability of the MSSM as a solution to the hierarchy problem. These constraints can be significantly…
Exothermic Dark Matter
Peter W. Graham, Roni Harnik, Surjeet Rajendran +1
We propose a novel mechanism for dark matter to explain the observed annual modulation signal at DAMA/LIBRA which avoids existing constraints from every other dark matter direct de…
A Little Solution to the Little Hierarchy Problem: A Vector-like Generation
Peter W. Graham, Ahmed Ismail, Surjeet Rajendran +1
We present a simple solution to the little hierarchy problem in the MSSM: a vector-like fourth generation. With O(1) Yukawa couplings for the new quarks, the Higgs mass can natural…
Experimental constraints on the free fall acceleration of antimatter
Daniele S. M. Alves, Martin Jankowiak, Prashant Saraswat
In light of recent experimental proposals to measure the free fall acceleration of antihydrogen in the earth's gravitational field, we investigate the bounds that existing experime…
