Invited by the School of Physics and Technology, Professor Xinchou Lou of the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences (CAS), and the University of Texas at Dallas, presented colloquium titled “Science exploration – secret of microscopic world and origin of universe”, on December 22, conference room 435, Xingjian building. Teachers, graduate students and undergraduates from School of Physics and Technology attended this seminar.
Professor Xinchou Lou is a well-known experimental particle physicist, researcher of IHEP, and professor at the University of Texas at Dallas (UTD) and former Head of UTD’s Physics Department. He was selected “Overseas well known scientist” (2007) by the Chinese Academy of Sciences, China’s distinguished scientist (2012), and Director of the experimental physics division of IHEP (2013.7 – 2020.3), IHEP’s principal scientist for its the LHC and CEPC programs, member of BESIII Executive Board, and project director of the CEPC study group.
In this colloquium, Professor Xinchou Lou introduced two of the most important discoveries in recent years: the discovery of the Higgs particle and the detection of gravitational waves. The former discovery provided an experimental fundamental for human studying microscopic world, the latter confirmed Einstein’s prediction in general relativity theory. In the standard model of particle physics, Higgs particle is the source of matter’s mass, and Higgs particle is believed to be related with unknown nature’s secret. Scientists are building next generation experiments for detection of many more gravitational waves, which will be used to detect the gravitational waves generated in the origin of universe. And scientists will start next generation scientific exploration using experiments for Higgs and gravitational waves.
