QCD sum rules for nucleon two-point function in nuclear medium
S. Mallik, Hiranmaya Mishra
We derive QCD sum rules from the nucleon two-point function in nuclear medium, calculating its specral function in chiral perturbation theory to one loop. Our calculation shows the…

Rho parameters from odd and even chirality, thermal QCD sum rules
S. Mallik, Krishnendu Mukherjee
Like the even chirality correlation functions of, say, the two vector currents, one can also consider odd chirality correlation functions to write thermal QCD sum rules. They conta…

Absence of second order phase transition in theory
S. Mallik, K. Mukherjee
We calculate the self-energy at finite temperature in scalar theory to second order in a modified perturbation expansion. Using the renormalisation group equation to tame th…
