报告摘要

For only a few millionths of a second after the Big Bang, our universe was in the form of a hot and dense soup of quarks and gluons, which cooled down rapidly to form protons, neutrons, and other such normal nuclear matter. The discovery and characterization of this new phase of matter called the quark-gluon plasma (QGP), require the creation of a sufficiently large and extended volume of hot and dense matter, which is possible by colliding heavy-ions at ultra-relativistic energies.

The Large Hadron Collider (LHC) at CERN, commissioned in the year 2009, has delivered colliding beams of proton-proton, proton-lead, xenon-xenon and lead-lead at unprecedented energies. The ALICE (A Large Ion Collider Experiment) collaboration at the LHC has carried out a comprehensive study of the majority of particles emitted in these collisions to study the quantum chromodynamics (QCD) phase transition and to characterize the QGP phase. In the presentation, I will discuss the recreation of the baby universe in the laboratory at the LHC and the future program.


报告人简介:

Prof. Tapan Kumar Nayak received his Ph.D. from Michigan State University, USA, in 1990. From 1990-1993, he worked as a postdoc at Columbia University, USA, in the PHENIX and E802 Collaborations. During 1994-1996, he joined GSI, Germany, as a Guest Scientist and worked in the WA98 experiment. Then, he moved to India and joined HBNI (VECC, Kolkata) as a Professor since 2005-2019. He is now actively involved also in the STAR experiment. He is now a visiting Professor in NISER, India, and also the Deputy Spokesperson of the ALICE experiment for the period of 2017-2019. He has been honored as a fellow of the Indian Academy of Sciences and the National Academy of Sciences, India. His specializations comprise of search and studies of QGP properties, probing the QCD Critical Point, the study of Disoriented Chiral Condensate (DCC) and phases of nuclear. He has also been involved in many decision-making bodies in India and also administrative works. He has mentored a large number of Ph.D. scholars and Postdoctoral fellows belonging to WA98, STAR, and ALICE experiments.
