We perform an analysis of the form factors that rule the structure-dependent amplitude in the radiative pion decay. The resonance contributions to π → e νeγ decays are computed through the proper construction of the vector and axial-vector form factors by setting the QCD driven asymptotic properties of the three-point Green functions V V P and V AP , and by(More)

We construct the most general chirally invariant Lagrangian for mesons in the presence of external sources coupled to the tensor current ¯ ψ σ µν ψ. In order to have only even terms in the chiral expansion, we consider the new source of O(p 2). With this choice, we build the even-parity effective Lagrangian up to the p 6-order (NLO). While there are only 4(More)

The most precise top quark mass measurements use kinematic reconstruction methods, determining the top mass parameter of a Monte Carlo event generator m_{t}^{MC}. Because of hadronization and parton-shower dynamics, relating m_{t}^{MC} to a field theory mass is difficult. We present a calibration procedure to determine this relation using hadron level QCD(More)
