Baryon chiral perturbation theory with virtual photons and leptons
Nopmanee Supanam, Harold W. Fearing, Yupeng Yan
We construct the general pion-nucleon SU(2) Lagrangian including both virtual photons and leptons for relativistic baryon chiral perturbation theory up to fourth order. We include…
Low-Energy Signals from Kinetic Mixing with a Warped Abelian Hidden Sector
Kristian L. McDonald, David E. Morrissey
We investigate the detailed phenomenology of a light Abelian hidden sector in the Randall-Sundrum framework. Relative to other works with light hidden sectors, the main new feature…
Broken Symmetry as a Stabilizing Remnant
Sandy S. C. Law, Kristian L. McDonald
The Goldberger-Wise mechanism enables one to stabilize the length of the warped extra dimension employed in Randall-Sundrum models. In this work we generalize this mechanism to mod…
Hylogenesis: A Unified Origin for Baryonic Visible Matter and Antibaryonic Dark Matter
Hooman Davoudiasl, David E. Morrissey, Kris Sigurdson +1
We present a novel mechanism for generating both the baryon and dark matter densities of the Universe. A new Dirac fermion X carrying a conserved baryon number charge couples to th…
Unravelling an Extra Neutral Gauge Boson at the LHC using Third Generation Fermions
Ross Diener, Stephen Godfrey, Travis A. W. Martin
We study the potential to use measurements of extra neutral gauge bosons (Z') properties in pp collisions at the Large Hadron Collider to unravel the underlying physics. We focus o…
An Unusual Two Higgs Doublet Model from Warped Space
We-Fu Chang, John N. Ng, A. P. Spray
We study a simple two Higgs doublet model (2HDM) in the Randall-Sundrum scenario, with an IR brane localized Higgs field and a second doublet arising from a condensate d…
