Academic Events

Prof. Zhao Zhengguo from University of Science and Technology of China came to our school for academic exchanges

Invited by the school of physics and technology, prof. Zhao Zhengguo from University of Science and Technology of China gave a colloquium titled as “Exploring the Infinitive Small with Particle Accelerator”at the XingJian building conference room (437) in the afternoon on Jan. 6, 2020. Relevant professors and graduate students attended the meeting and had fruitful discussions with Prof. Zhao.

Prof. Zhao, an academician of Chinese Academy of science, is a professor of physics in the Chinese University of Science and Technology. He is a world famous senior experiential particle physicist, was in charge of BES experiment and responsible for the deep investigation of tau-charm physics, light hadron spectroscopy, charmonium and charm physics. He was the winner of the First prize of natural science of Chinese Academy of Sciences in 2000 and the Second prize of National Natural Science in 2001 due to his excellent contribution to the “studies of psi(2S) and other charmonium physics”, as well as the winner of many other prizes. He is proud of his unique contribution of leading the R value measurements at BES experiment in 1998-2001, where they improved the precision of the R value between 2 and 5 GeV by a factor of 2 to 3. He was elected to be an academician of Chinese Academy of science in 2013.

Particle physics is to find out answers to the questions: what are the fundamental building blocks of our universe, and how they interact with each other? These typically entails particles having high energy and the interactions of the simplest kinds of particles: leptons, quarks and field quanta with size down to 10-17 m. Prof. Zhoa’s presentation introduced the standard model picture of the elementary particle physics, and how they use cutting-edge technology to build big facilities like particle accelerators and detectors to discover new particles, new forces as well as new science rules. The LHC experiments, CEPC experiments and a possible tau-charm factory is introduced in this lecture.
