Global fits and the 95 GeV diphoton excesses in the Supersymmetric Georgi-Machacek Model
Yingnan Xu, Dikai Li, Roberto Vega +2
Recently the ATLAS and CMS experiments have reported modest excesses in the diphoton channel at around 95 GeV.~A number of recent studies have examined whether these could be due t…
Light (and darkness) from a light hidden Higgs
Roberto Vega, Roberto Vega-Morales, Keping Xie
We examine light diphoton signals from extended Higgs sectors possessing (approximate) fermiophobia with Standard Model (SM) fermions as well as custodial symmetry. This class of H…
The Supersymmetric Georgi-Machacek Model
Roberto Vega, Roberto Vega-Morales, Keping Xie
We show that the well known Georgi-Machacek (GM) model can be realized as a limit of the recently constructed Supersymmetric Custodial Higgs Triplet Model (SCTM) which in general c…
Supersymmetric Custodial Higgs Triplets and the Breaking of Universality
Mateo Garcia-Pepin, Stefania Gori, Mariano Quiros +3
Higgs triplet models are known to have difficulties obtaining agreement with electroweak precision data and in particular constraints on the parameter. Either a global $SU(2)_L…
The Drell-Hearn Sum Rule at Order Alpha**3
Duane A. Dicus, Roberto Vega
The Drell-Hearn-Gerasimov-Iddings (DHGI) sum rule for electrons is evaluated at order and shown to agree with the Schwinger contribution to the anomalous magnetic moment.
Measuring the neutrino mass using intense photon and neutrino beams
Duane A. Dicus, Wayne W. Repko, Roberto Vega
We compute the cross section for neutrino-photon scattering taking into account a neutrino mass. We explore the possibility of using intense neutrino beams, such as those available…
