OPE-RchiT matching at order alpha_s: hard gluonic corrections to three-point Green functions
Matthias Jamin, Vicent Mateu
In this work we push the matching between the QCD operator product expansion (OPE) and resonance chiral theory (RchiT) to order alpha_s. To this end we compute two- and three-point…
Novel patterns for vector mesons from the large-Nc limit
O. Cata, V. Mateu
We report on a relation between the decay constants of ρ-like J^{PC}=1^{--} vector mesons, which arises solely from the perturbative analysis of the VV, TT and VT correlators at or…
Universal Bounds for SU(3) Low Energy Constants
V. Mateu
In this paper bounds for L_1, L_2 and L_3 are obtained in Chiral Perturbation Theory with three flavours. At the same time we test the compatibility of this theory with axiomatic p…
Dispersion Relation Bounds for pi pi Scattering
A. V. Manohar, V. Mateu
Axiomatic principles such as analyticity, unitarity and crossing symmetry constrain the second derivative of the pi pi scattering amplitudes in some channels to be positive in a re…
Form Factors in the radiative pion decay
V. Mateu, J. Portoles
We perform an analysis of the form factors that rule the structure-dependent amplitude in the radiative pion decay. The resonance contributions to pion -> e nu_e gamma decays are c…
