Abstract:

The production of same-sign lepton pairs from proton-proton collisions occurs rarely in the Standard Model (SM). However, physics Beyond Standard Model (BSM) can significantly enhance the cross section of these production processes. The final state is favoured in many BSM searches because of its relatively low background. In this seminar, I will focus on new physics searches with same-sign leptons and missing transverse momentum at the Large Hadron Collider.

 

Biography:

Dr. Xingguo Li is a Research Fellow at the Deutsches Elektronen-Synchrotron (DESY) in Hamburg, Germany. He is currently leading the in situ jet calibration group consisting of 50 physicist in the ATLAS Collaboration and acting as a member of the Early Career Scientists Board representing 1000 Young Scientists at ATLAS. He obtained his Ph.D degree from University of Manchester in 2016 and his Master Physics degree from Manchester University in 2012. From 2016 to 2018, he was a Chung-Yao Chao Fellow with Shanghai Jiao Tong University. His main research interests lie in precision measurements as well as new physics searches at the Large Hadron Collider.
