Analytic Amplitude Models for Forward Scattering
K. Kang, J. R. Cudell, V. V. Ezhela +5
We report on fits of a large class of analytic amplitude models for forward scattering against the comprehensive data for all available reactions. To differentiate the goodness of…
Analytic parametrizations of the non-perturbative Pomeron and QCD-inspired models
B. Nicolescu, J. R. Cudell, V. V. Ezhela +5
We consider several classes of analytic parametrizations of hadronic scattering amplitudes, and compare their predictions to all available forward data (proton- proton, antiproton-…
New measures of the quality and of the reliability of fits applied to forward hadronic data at t=0
J. R. Cudell, K. Kang, V. V. Ezhela +5
We develop five new statistical measures of the quality of fits, which we combine with the usual confidence level to determine the models which fit best all available data for tota…
Does F2 need a hard pomeron?
J. R. Cudell, G. Soyez
We show that the latest HERA measurements of F2 are compatible with the existence of a triple pole at J=1. Such a structure also accounts for soft forward hadronic amplitudes, so t…
Hadronic scattering amplitudes: medium-energy constraints on asymptotic behaviour
J. R. Cudell, V. Ezhela, P. Gauron +5
We consider several classes of analytic parametrisations of hadronic scattering amplitudes, and compare their predictions to all available forward data (p p, pbar p, pi p, K p, gam…
Large pion pole in Z_{S}^{MOM}/Z_{P}^{MOM} from Wilson action data
J. R. Cudell, A. Le Yaouanc, C. Pittori
We show that, contrarily to recent claims, data from the Wilson (unimproved) fermionic action at three different beta values demonstrate the presence of a large Goldstone boson con…
