Kinetic Mixing at Strong Coupling
Michele Del Zotto, Jonathan J. Heckman, Piyush Kumar +2
A common feature of many string-motivated particle physics models is additional strongly coupled U(1)'s. In such sectors, electric and magnetic states have comparable mass, and int…
Dark Matter Production Mechanisms with a Non-Thermal Cosmological History - A Classification
Gordon L. Kane, Piyush Kumar, Brent D. Nelson +1
We perform a comprehensive study of models of dark matter (DM) in a Universe with a non-thermal cosmological history, i.e with a phase of pressure-less matter domination before the…
R-Parity Conservation from a Top Down Perspective
Bobby S. Acharya, Gordon L. Kane, Piyush Kumar +2
Motivated by results from the LHC and dark matter searches, we study the possibility of phenomenologically viable R-parity violation in GUT models from a top-down point of…
OPE Methods for the Holomorphic Higgs Portal
Piyush Kumar, Daliang Li, David Poland +1
We develop a systematic and general approach to study the effective Higgs Lagrangian in a supersymmetric framework in which the Higgs fields in the visible sector couple weakly to…
"L=R" - as the Origin of Leptonic 'RPV'
Claudia Frugiuele, Thomas Gregoire, Piyush Kumar +1
A classification of phenomenologically interesting supersymmetric extensions of the Standard-Model with a symmetry is presented. Some of these are consistent with subsets…
"L=R" -- Lepton Number at the LHC
Claudia Frugiuele, Thomas Gregoire, Piyush Kumar +1
We perform a detailed study of a variety of LHC signals in supersymmetric models where lepton number is promoted to an (approximate) U(1)_R symmetry. Such a symmetry has interestin…
