- Speaker: Victor Shang, Physics PhD Graduate Student
- Abstract: One of the fundamental open questions that cannot be currently explained by the Standard Model is the particle nature of dark matter. Though astrophysical observations provide indirect evidence of its existence, dark matter has not been directly measured so far. However, under certain assumptions, dark matter may be possible to produce and detect at high energy particle colliders like the LHC.
This thesis presents a search for dark matter produced in association with top quarks in data collected by the CMS detector at the LHC, corresponding to 138 fb-1 of proton-proton collisions at a center-of-mass energy of 13 TeV. Production of dark matter particles in association with both a single top quark and a pair of top quarks are considered. The search is performed in three separate channels depending on the number of leptons in the final state, which include the all hadronic, single lepton, and dileptonic final states. The primary strategy of the search is to look for an excess of events with respect to the background-only prediction in events with a large imbalance in the transverse momentum. The results are interpreted in the context of a simplified model in which either a scalar or pseudoscalar mediator couples to top quarks and to dark matter fermions. Future prospects for improving the search are also discussed - Host: Tulika Bose
Tuesday, November 26th, 2024
- Climate & Diversity
- Current Issues in Physics: TedTalk: The power of vulnerability - Brené Brown
- Time: 12:00 pm - 1:00 pm
- Place: Chamberlin 5310 or over Zoom
- Abstract: Brené Brown studies human connection -- our ability to empathize, belong, love. In a poignant, funny talk at TEDxHouston, she shares a deep insight from her research, one that sent her on a personal quest to know herself as well as to understand humanity. This video is an opportunity for discussion on the way that each of us experiences shame or discomfort in equity work.
- Host: Rachel Zizmann
- Network in Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS) Seminar
- High-Energy Neutrinos: A New Trail Towards New Physics
- Time: 12:00 pm
- Place: Meeting ID: 989 8774 9464 Passcode: 986897
- Speaker: Carlos Arguelles Delgado , Harvard University
- Abstract: The observation of high-energy astrophysical neutrinos by the IceCube Neutrino Observatory has opened up a new window to the universe. These neutrinos traverse the longest distances from their sources and have the largest energy ever observed. These neutrinos open a new trail to search for new physics that covers parameter space not accessible to terrestrial neutrino experiments. In this Seminar, I will explain the inner workings of the IceCube neutrino observatory, discuss the latest measurements of high-energy astrophysical neutrinos, and provide examples of new physics searches with these neutrinos.
