S and T for SCFTs
Jonathan J. Heckman, Piyush Kumar, Brian Wecht
We develop a general set of methods for computing the oblique electroweak parameters S and T for bottom-up and top-down motivated scenarios in which the Higgs weakly mixes with a s…
"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…
Mixed Wino-Axion Dark Matter in String/M Theory and the 130 GeV Gamma-line "Signal"
Bobby Samir Acharya, Gordon Kane, Piyush Kumar +2
String/M theory compactifications with low energy supersymmetry tend to predict that dark matter has two components: axions and WIMPs \cite{1004.5138,1204.2795}. In accord with thi…
Compactified String Theories -- Generic Predictions for Particle Physics
Bobby Samir Acharya, Gordon Kane, Piyush Kumar
In recent years it has been realized that in string/ theories compactified to four dimensions which satisfy cosmological constraints, it is possible to make some generic predict…
The Higgs as a Probe of Supersymmetric Extra Sectors
Jonathan J. Heckman, Piyush Kumar, Brian Wecht
We present a general method for calculating the leading contributions to h -> gg and h -> gamma gamma in models where the Higgs weakly mixes with a nearly supersymmetric extra sect…
