Monoenergetic Neutrinos from WIMP Annihilation in Jupiter
George M. French, Marc Sher
Weakly interacting massive particles (WIMPs) can be captured by the Sun and annihilate in the core, which may result in production of kaons that can decay at rest into monoenergeti…
Flavor Changing Neutral Currents in the Higgs Sector
Marc Sher
This review considers models with extended Higgs sectors in which there are tree-level flavor-changing neutral currents (FCNC) mediated by scalars. After briefly reviewing models w…
in the 2HDM and slightly beyond -- an updated view
P. M. Ferreira, B. L. Gonçalves, F. R. Joaquim +1
The recent measurement of the muon anomaly continues to defy a Standard Model explanation, but can be accommodated within the framework of two Higgs doublet models. If one…
Suppression of the Higgs Dimuon Decay
P. M. Ferreira, Marc Sher
It is often stated that elimination of tree-level flavor-changing neutral currents in multi-Higgs models requires that all fermions of a given charge to couple to the same Higgs bo…
Constraints on the Parameter Space in an Inert Doublet Model with two Active Doublets
Marco Merchand, Marc Sher
We study a three Higgs doublet model where one doublet is inert and the other two doublets are active. Flavor changing neutral currents are avoided at tree-level by imposing a soft…
Breaking of Lorentz Invariance in Electron-Proton Parity Violation
Alexander Michel, Marc Sher
A popular framework for exploring Lorentz violation is the Standard Model Extension. This extension contains a large number of parameters that can be bounded in various experiments…
