Lepton flavor specific extended Higgs model

Physical Review D (2023)

B. L. Gonçalves, Matthew Knauss and Marc T Sher

In extended Higgs models, a discrete symmetry is needed in the quark sector to avoid tree-level flavor-changing neutral currents. However, ...

Monoenergetic neutrinos from WIMP annihilation in Jupiter

Physical Review D (2022)

Marc T Sher and George M. French

Weakly interacting massive particles (WIMPs) can be captured by the Sun and annihilate in the core, which may result in ...

Flavor-changing neutral currents in the Higgs sector

Modern Physics Letters A (2022)

This review considers models with extended Higgs sectors in which there are tree-level flavor-changing neutral currents (FCNC) mediated by scalars. ...

( g − 2 ) μ in the 2HDM and slightly beyond: An ...

Physical Review D (2021)

P. M. Ferreira, B. L. Gonçalves, F. R. Joaquim and Marc T Sher

The recent measurement of the muon g−2 anomaly continues to defy a Standard Model explanation but can be accommodated within the framework ...

Suppression of the Higgs boson dimuon decay

Physical Review D (2020)

P. M. Ferreira and Marc T Sher

It is often stated that elimination of tree-level flavor-changing neutral currents in multi-Higgs models requires that all fermions of a ...

Constraints on the parameter space in an inert doublet model ...

Journal of High Energy Physics (2020)

Marco Merchand and Marc T Sher

We study a three Higgs doublet model where one doublet is inert and the other two doublets are active. Flavor ...

Breaking of Lorentz invariance in electron-proton parity violation

Physical Review D (2019)

Alexander Michel and Marc T Sher

A popular framework for exploring Lorentz violation is the Standard Model extension. This extension contains a large number of parameters ...

Is the radion a bulk Higgs doublet?

Journal of Physics G: Nuclear and Particle Physics (2019)

Marco Merchand, Marc T Sher and Keith Thrasher

In 2013, Geller, Bar-Shalom and Soni (GBS) proposed a Randall-Sundrum model with a bulk SU(2) doublet. They found that the ...

Radion-Higgs mixing in 2HDMs

Journal of High Energy Physics (2018)

Marco Merchand, Marc T Sher and Keith Thrasher

We study the custodial Randall-Sundrum model with two Higgs doublets localized in the TeV brane. The scalar potential is CP- ...

Three doublet lepton-specific model

PHYSICAL REVIEW D (2018)

Marco Merchand and Marc Sher

In the lepton-specific version of two Higgs doublet models, a discrete symmetry is used to couple one Higgs boson, Phi(2), ...

Detecting a heavy neutrino electric dipole moment at the LHC

Physics Letters B (2018)

Marc Sher and Justin R. Stevens

The milliQan Collaboration has proposed to search for millicharged particles by looking for very weakly ionizing tracks in a detector ...

Physics 201: Modern Physics

Arts & Sciences Open Educational Resources (2015)

Jamie Leach and Marc T. Sher

Following the spirit of the new curriculum, it was decided to convert the Modern Physics course, Physics 201, into a ...

Dark two Higgs doublet model

Physical Review D (2013)

Hye-Sung Lee, Marc Sher and Hye-Sung Lee

We perform a detailed study of a specific two Higgs doublet model with a U (1) gauge symmetry, instead of ...

Heavy Higgs searches and constraints on two Higgs doublet models

Physical Review D (2013)

Chien-Yi Chen, Sally Dawson and Marc Sher

Since the discovery of a Higgs boson at the LHC and the measurement of many of its branching ratios, there ...

Could the LHC two-photon signal correspond to the heavier scalar ...

Physical Review D (2012)

P. M. Ferreira, Rui Santos, Joao P. Silva and Marc Sher

LHC has reported tantalizing hints for a Higgs boson of mass 125 GeV decaying into two photons. We focus on ...

Implications of the LHC two-photon signal for two-Higgs-doublet models

Physical Review D (2012)

P. M. Ferreira, Rui Santos, Joao P. Silva and Marc Sher

We study the implications for two-Higgs-doublet models of the recent announcement at the LHC giving a tantalizing hint for a ...

Non-Abelian Gauge Symmetries beyond the Standard Model

Advances in High Energy Physics (2012)

Hoang Ngoc Long, Vicente Pleitez, Marc Sher and Masaki Yasue

Supersymmetric leptophilic Higgs model

Physical Review D (2011)

Gardner Marshall and Marc Sher

In the leptophilic model, one Higgs doublet couples to quarks and another couples to leptons. We study the supersymmetric version ...
