- Dark Matter in Dilepton Production
- Time: 3:00 pm - 4:00 pm
- Place: 5280 Chamberlin Hall
- Speaker: Nirmal Raj, University of Oregon
- Abstract: At the LHC a standard search channel for new physics is the production of a pair of leptons. New resonances or contact operators can be gleaned from peaks or broad deviations respectively in the invariant mass distribution (mll) of this channel. I'll demonstrate in this talk how hidden sectors can show up in dileptonic events through radiative corrections to the Standard Model process, giving rise to unique features in mll, as well as in leptonic angular distributions. One compelling possibility that can be probed is that of dark matter with scalar messengers coupling it to the quarks and leptons. I will present constraints from dilepton spectrum measurements at the LHC and dark matter experiments, and make predictions for the bounds from the high luminosity 14 TeV LHC as well as a 100 TeV collider.

- Neutrino oscillations at current and future experiments
- Time: 3:00 pm - 4:00 pm
- Place: 5280 Chamberlin Hall
- Speaker: Pilar Coloma
- Abstract: The large value of $theta_{13}$ has opened a door to determine the ordering of neutrino masses and the amount of CP violation in the leptonic sector. In the case of the neutrino mass ordering, the situation for the upcoming years is particularly promising and a measurement may be achievable in the near future. The determination of the Dirac CP-violating phase $delta$ is more challenging and will depend on several factors, though. In this talk, I will summarize the prospects for the current and future generations of neutrino oscillation experiments for these two observables, and discuss the main challenges that they will have to face.
