Preliminary Exam
Portal Matter, Kinetic Mixing, and Muon g − 2
Date: Tuesday, December 13th
Time: 10:00 am
Place: 5280 Chamberlin
Speaker: Ricardo Alexandre Dos Santos Ximenes Filho, Physics Graduate Student
Abstract: We present a minimal toy model construction using leptonic portal matter that addresses the muon g − 2 anomaly through chiral enhancement. While the chiral enhancement mechanism is reminiscent of fermiophobic Z′ gauge models, the parameter space motivated by the kinetic mixing/vector portal dark matter model paradigm is vastly different and readily available to be explored in current and forthcoming experiments. We further explore a detailed realization of this construction that utilizes a SU(2)xSU(2) dark gauge group, that is broken first to a conserved dark U(1) by a Higgs bi-doublet and the dark U(1) is then further broken by a pair of triplet Higgs fields to yield the sub-GeV dark photon.
