Fun with colours: the standard model with two colour QCD has radically different long distance physics
Saumen Datta, Sourendu Gupta, Rishi Sharma
In our world the standard model of particle physics contains within it the fairly intractable theory called QCD. A toy version with two colours is often studied as a model confinin…
Chiral symmetry breaking and chemical equilibrium in a heavy-ion collisions
Sourendu Gupta, Jajati K. Nayak, Sushant K. Singh
We examine the thermalization of an ensemble of the octet of pseudoscalar mesons, in the isospin symmetric limit, whose interactions are constrained through chiral symmetry, unitar…
Real time warm pions from the lattice using an effective theory
Sourendu Gupta, Rishi Sharma
Lattice measurements provide adequate information to fix the parameters of long distance effective field theories in Euclidean time. Using such a theory, we examine the analytic co…
Epidemic parameters for COVID-19 in several regions of India
Sourendu Gupta
Bayesian analysis of publicly available time series of cases and fatalities in different geographical regions of India during April 2020 is reported. It is found that the initial a…
Inferring epidemic parameters for COVID-19 from fatality counts in Mumbai
Sourendu Gupta
Epidemic parameters are estimated through Bayesian inference using the daily fatality counts in Mumbai during the period from March 31 to April 14. A doubling time of 5.5 days (med…
Freeze-out and thermalization in relativistic heavy ion collisions
Sourendu Gupta, Debasish Mallick, Dipak Kumar Mishra +2
High energy heavy-ion collisions in laboratory produce a form of matter that can test Quantum Chromodynamics (QCD), the theory of strong interactions, at high temperatures. One of…
