Please contact rishi(at)theory(dot)tifr(dot)res(dot)in for the zoom meeting id and the password for this seminar.The screening masses of mesons provide a gauge invariant and definite order parameter of chiral symmetry restoration. Different mesonic correlation lengths for flavor non-singlets, at least up to NLO, are well-defined gauge invariant physical quantities calculated earlier using the perturbative resummation techniques. The NLO perturbative results explain the available non-perturbative lattice QCD results at the high-temperature regime. Very recently, we have studied the spatial correlation lengths of various mesonic observables using the non-perturbative Gribov resummation, both for quenched QCD and (2 + 1) flavor QCD. The study follows the analogies with the NRQCD effective theory, a well-known theory for studying heavy quarkonia at zero temperature. In this talk, I will discuss our finding and improvement over the existing perturbative result. ---------------------------------------------------------------------------------------- Reference: https://doi.org/10.1016/j.physletb.2023.138143---------------------------------------------------------------- |
