"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…
Can the 126 GeV boson be a pseudoscalar?
Baradhwaj Coleppa, Kunal Kumar, Heather E. Logan
We test the possibility that the newly-discovered 126 GeV boson is a pseudoscalar by examining the correlations among the loop-induced pseudoscalar decay branching fractions to $γγ…
Chiral-Symmetry-Violating Effects and Near-Maximal Mixing of Scalar Gluonium and Quark Mesons
T. G. Steele, D. Harnett, R. T. Kleiv +1
Gaussian QCD sum-rules are used to analyze all possible two-point correlation functions of scalar gluonic and quark currents. The independent predictions of the masses and relative…
Resonantly enhanced pair production in a simple diatomic model
François Fillion-Gourdeau, Emmanuel Lorin, André D. Bandrauk
A new mechanism for the production of electron-positron pairs from the interaction of a laser field and a fully stripped diatomic molecule in the tunneling regime is presented. Whe…
High-energy suppression of the Higgsstrahlung cross-section in the Minimal Composite Higgs Model
Katy Hartling, Heather E. Logan
If the Higgs boson is composite, signs of this compositeness should appear via a formfactor-like suppression of Higgs scattering cross sections at momentum transfers above the comp…
