Automatic predictions in the Georgi-Machacek model at next-to-leading order accuracy
Celine Degrande, Katy Hartling, Heather E. Logan +2
We study the phenomenology of the Georgi-Machacek model at next-to-leading order (NLO) in QCD matched to parton shower, using a fully-automated tool chain based on MadGraph5_aMC@NL…
The spontaneous breaking Twin Higgs
Hugues Beauchesne, Kevin Earl, Thomas Grégoire
The Twin Higgs model seeks to address the little hierarchy problem by making the Higgs a pseudo-Goldstone of a global symmetry that is spontaneously broken to . Gaug…
Evidence of sub-nucleonic degrees of freedom in J/ photoproduction in ultraperipheral collisions at the CERN Large Hadron Collider
E. Andrade-II, I. González, A. Deppman +1
We present calculations for the incoherent photoproduction of J/ vector mesons in ultra-peripheral heavy ion collisions (UPC) in terms of hadronic interactions. This study was c…
Properties of Excited Charm and Charm-Strange Mesons
Stephen Godfrey, Kenneth Moats
We calculate the properties of excited charm and charm-strange mesons. We use the relativized quark model to calculate their masses and wavefunctions that are used to calculate rad…
Compressing the Inert Doublet Model
Nikita Blinov, Jonathan Kozaczuk, David E. Morrissey +1
The Inert Doublet Model relies on a discrete symmetry to prevent couplings of the new scalars to Standard Model fermions. This stabilizes the lightest inert state, which can then c…
Probe of new light Higgs bosons from bottomonium chi_{b0} decay
Stephen Godfrey, Heather E. Logan
We calculate the branching ratios of chi_{b0} --> tau+ tau- via an s-channel Higgs boson and estimate the sensitivity to this process from Upsilon --> gamma chi_{b0} --> gamma tau+…
