“…. This discrepancy resulted in three new dispersive calculations of the γW contribution to g V [7,9,10], which gave results slightly closer to the recent dispersive determination [5,6,8,12]. The first lattice-QCD evaluations of the hadronic contributions to the γW box diagram in the pion and neutron decays are also coming online [28,29,30,31].…”

“…The latest and most precise measurement by the bottle method was performed at Los Alamos National Laboratory (LANL) [3]. It reaches a relative accuracy between 3 and 4 permille, while theoretical predictions have an error of the same order of magnitude [4,5,6,7,8,9,10,11,12] and heavily rely on the experimental value of the axial-vector coupling constant. Future measurements by the beam method will decrease the uncertainty by a factor 10.…”

Radiative Corrections to Neutrino-Nucleon Scattering in Effective Field Theory

We study radiative corrections to neutron beta decay and lowenergy (anti)neutrino-nucleon scattering within a top-down effective field theory approach. As it was recently shown, a few electromagnetic and electroweak low-energy coupling constants in heavy-baryon chiral perturbation theory are yet to be determined. Performing matching to the four-fermion effective field theory, we relate these low-energy constants to correlation functions of vector and axial-vector currents. Such relations allow us to clarify explicitly scheme dependence for radiative corrections to neutron decay and low-energy chargedcurrent (anti)neutrino scattering, to provide a robust prediction of leading in the electromagnetic coupling constant contributions, and to achieve a clear separation of short-distance from long-distance contributions.

We study a relativistic fluid with longitudinal boost invariance in a quantum-statistical framework as an example of a solvable non-equilibrium problem. For the free quantum field, we calculate the exact form of the expectation values of the stress-energy tensor and the entropy current. For the stress-energy tensor, we find that a finite value can be obtained only by subtracting the vacuum of the density operator at some fixed proper time τ0. As a consequence, the stress-energy tensor acquires non-trivial quantum corrections to the classical free-streaming form.
