Listening to Learn: Origin of Mass

Department of Education in Science and Mathematics National Council of Educational Research and Training Webinar Series: Listening to Learn (Session – 97) Origin of Mass Dr. V. Ravindran The Institute of Mathematical Sciences Taramani, Chennai Telecast on PMeVidya Channels #9, #10, #11, and #12 Friday, February 07, 2024; 10:00 – 11:00 AM (IST) In the General Theory of Relativity, mass is not only a measure of matter but also a key source of gravity, affecting the curvature of spacetime. The origin of mass is a fundamental question in particle physics and cosmology. The most satisfactory answer to the origin of mass of elementary particles stems from the Higgs mechanism, which is part of the Standard Model of particle physics. The mechanism demonstrates how the particles acquire mass through their interaction with the Higgs field, an invisible energy field that permeates space. The Higgs boson, discovered in 2012 at CERN, Geneva is the quantum excitation of this field and serves as evidence for the existence of the Higgs mechanism. While the Higgs mechanism provides the answer, the strong interaction within hadrons plays a much more significant role in obtaining the mass of the composite particles that fill the most part of the visible universe. About the Speaker: Dr. V. Ravindran is currently the Professor and Director of the Institute of Mathematical Sciences, Chennai from where he obtained his doctoral degree as well. He has been the post-doctoral fellow at the Tata Institute of Fundamental Research (TIFR) Mumbai; Physical Research Laboratory (PRL), Ahmedabad; and at the Deutsches Elektronen-Synchrotron (DESY), Zeuthen, Germany. He is also an Adjunct Professor at the Indian Institute of Science Education and Research, Mohali. Prior to joining IMSc in 2012, Professor Ravindran was a faculty member at the famous Harish Chandra Research Institute during 1999 – 2012. Dr. Ravindran is a Fellow of the Indian Academy of Sciences, Bengaluru; The National Academy of Sciences, Prayagraj; and the Academy of Sciences, Chennai. Professor Ravindran has been Visiting Scientist at the Japan Society of Promotion of Sciences in 2005; FOM Visiting Professor, Lorentz Institute, The Netherlands during 2005 – 07; Visiting Scientist, Theory Group, DESY, Zeuthen; Visiting Scientist, Theory Group, The European Organization for Nuclear Research (CERN); and Visiting Professor at the Pauli Centre for Theoretical Studies, Zurich, Switzerland during 2017. Dr. Ravindran is a theoretical high energy physicist and his area of research is precision physics relevant for physics studies at high energy colliders such as Large Electron-Positron Collider, Tevatron, Large Hadron Collider, Electron Ion Collider etc. For the Large Hadron Collider, he has been involved in predicting inclusive rates for the production of Higgs boson(s) or a pair of leptons in Drell-Yan process or heavy state(s) in theories of large extra-dimensions. These results have played an important role both in the discovery of the Higgs boson at the LHC.
