Prof. Ashutosh Kotwal recently lectured at the CTEQ Summer School on Particle Physics, which was hosted by Peking University this year in Beijing. He lectured on QCD and Electroweak Phenomenology. During the same trip, he gave a colloquium at Tsinghua University and a seminar at the Institute of High Energy Physics (IHEP) in Beijing. In his seminar he discussed precision electroweak measurements and what they tell us about the energy scale of new physics beyond the Standard Model of Particle Physics. He discussed the motivation for a new electron-positron collider as a Higgs boson factory and a larger hadron collider with energy in the 100-200 TeV range. These projects are being discussed for siting in China and Europe and possible siting in the US.
