Heavy Quarkonium Production Phenomenology and Automation of One-Loop Scattering Amplitude Computations

Dr. Hua-Sheng Shao received his B.Sc. in physics from Peking University, China in 2009. He obtained his Ph.D. in theoretical physics from the School of Physics, Peking University in June 2014. His major research project in Prof. Kuang-Ta Chao’s group is heavy quarkonium production phenomenology. During his Ph.D. career, he was also invited to spend a year at the Conseil Européen pour la Recherche Nucléaire (CERN), from Sep 2012 to Aug 2013.  He then joined the MadGraph5_aMC@NLO international collaboration, which aims to provide a general framework for high-energy physicists (both theorists and experimentalists) to automatically perform precise theoretical predictions in quantum field theories. He is now a postdoctoral fellow working with Prof. Michelangelo Mangano, Prof. Stefano Frixione, Prof. Fabio Maltoni and Prof. Roberto Pittau at CERN, focusing on general high-energy physics phenomenology, especially on the physics at the Large Hadron Collider at CERN.
