- Preliminary Exam
- Portal Matter, Kinetic Mixing, and Muon g − 2
- 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.

- Thesis Defense
- Search for dark matter recoiling from a Higgs boson, which decays to tau lepton pairs, with the CMS detector at the LHC
- Time: 1:00 pm - 6:00 pm
- Place: 4274 Chamberlin
- Speaker: Jithin Madhusudanan Sreekala, Physics Graduate Student
- Abstract: This thesis describes search for dark matter particles recoiling from a Higgs boson at the CMS detector at the LHC where the Higgs subsequently decays to two tau leptons. The analysis uses 2017 and 2018 RUN II dataset collected by CMS experiment. This thesis discusses two scenarios, one where taus are resolved and one where taus are boosted.
