Revisiting the sphaleron and axion production rates in QCD at high temperatures
Sayak Guin, Sayantan Sharma
We report our new lattice results for the sphaleron rate calculated within a thermal effective field theory of soft SU(N) gluons whose momenta are below the magnetic scale, where $…

Probing QCD instantons using jet correlation observables in proton-proton collisions at the LHC
Sayak Guin, Swagatam Tah, Nihar Ranjan Sahoo +1
Discovery of instantons in colliders will provide experimental evidence for the topological properties of the QCD vacuum. In this work, we propose jet correlation observables that…

Understanding thermalization in a non-Abelian gauge theory in terms of its soft modes
Sayak Guin, Harshit Pandey, Sayantan Sharma
We measure the maximal Lyapunov exponent of physical states in a SU(2) gauge theory consisting of soft momentum modes both in and out-of-thermal equilibrium conditions using…
