Institute Lecture on 'Proton, whence comest thou spin?'

An Institute Lecture titled "Proton, whence comest thou spin? — The deep mysteries of the spin structure of the proton and enlightening solutions suggested by the gluon”  was organised on September 15 to be delivered by Prof. Abhay Deshpande, Department of Physics and Astronomy at Stony Brook University (SUNY), New York.

Prof. Abhay Deshpande is a Professor in the department of Physics and Astronomy at Stony Brook University (SBU-SUNY). He also serves as Director of Science for the Electron Ion Collider (EIC), at Brookhaven National Laboratory and is the founding Director of the Center for Frontiers in Nuclear Science (CFNS) at Stony Brook University, a joint initiative between Stony Brook University & Brookhaven National Laboratory. After doing M.Sc. in Physics from Indian Institute of Technology Kanpur in 1987, Prof. Deshpande have done his PhD in Experimental High Energy Physics from Yale University in 1995.

Prof. Deshpande's work interest and research areas are (1) Quantum Chromodynamics (QCD): QCD (structure of visible matter), Nucleon Spin (2) Understanding natural laws employing “spin” as a tool: Precision Electro-Weak (EW) & Beyond the Standard Model (BSM) physics and (3) How we learn & developing effective teaching techniques and tools. Honors and Awards bestowed on Prof. Deshpande are RIKEN President’s Special Prize for contributions to study of Nucleon Spin, Meritorious Faculty Award by Department of Physics & Astronomy at SBU, and Gibbs Medal (Valedictorian) by University of Bombay. He has authored around 400 peer review publications.

Prof. Deshpande has also delivered lectures and talks at numerous national and international conferences. He is also handling the responsibility of Project Director and Principle Investigator (PI) of Grants and the Group for DOE Nuclear Physics (Medium Energy) for RHIC Spin and JLab Physics program. He has been a visiting professor at IIT Bombay, IIT Kanpur, TIFR and University of Adelaide. He has been involved in Scientific collaboration and also affiliated to National and International Organizations/ Committees.

Below is the brief abstract of the lecture:

Did you know that despite almost 100 years of familiarity, we still do not understand the structure of the proton, the “basic building block" of all the visible matter in the universe? Did you know that contrary to the popular belief of being responsible for the “mass of the Universe”, the Higgs Boson, is responsible for less than 1% of its mass? At the heart of these profound truths is the mysterious “gluon", the force carrier in Quantum Chromodynamics (QCD), the theory that deals with the Strong Interactions in the Standard Model of Physics. This talk was given with the motivation to ‘take you on a journey from the experimental discovery of the proton’s "spin crisis" in 1988 to its current understanding, and then present an exciting future in which we hope to fully understand the “Glue That Binds Us All”.’
