"For years our program has aimed not only to present the progress of astronomy, but to give an opportunity to our members to hear, see, and visit with eminent scientists who actually are contributing to the ever-widening horizon of our knowledge of the universe. ”

Dr. Zhangbu Xu
Title: From Exotic Antimatter Search to Big Bang Recreation with the Biggest Colliders in the World
Description:
Bio Information: Research interests of Dr. Xu include the study of the properties of Quark-Gluon Plasma, a new form of matter believed to exist at the first-few microseconds after the Big Bang, using STAR Detector at the Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory (BNL). The group has used flow, (strangeness and charmed) hadron spectra and thermal e+e- pair radiation to study the QGP properties and the phase diagram of the strongly interacting Quantum Chromodynamics (QCD) matter. The search for and study of the properties of exotic antinuclei and hypernuclei. Discover and the study of the Breit-Wheeler process (two photons colliding to generate matter-antimatter). Also, the Study of the gluon junction as a possible tracer of baryon number. Research including to Imagine nuclei using spin-interference diffractive vector meson production in Ultra-peripheral nucleus-nucleus collisions (UPC) and Electron-Ion collisions (EIC) Research on silicon based of AC coupled Low Gain Avalanche Detector (AC-LGAD) technology for the ePIC time-of-Flight detector at the future Electron-Ion Collider (EIC) at BNL. Dr. Xu educational background includes a (PhD) from Yale University and a (B.S.) from USTC/China.
