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…
Pomeron effective intercept, logarithmic derivatives of in DIS and Regge models
P. Desgrolard, A. Lengyel, E. Martynov
The drastic rise of the proton structure function when the Björken variable decreases, seen at HERA for a large span of , may be damped when and $Q^2…
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…
On a three-body confinement force in hadron spectroscopy
S. Pepin, Fl. Stancu
Recently it has been argued that a three-body colour confinement interaction can affect the stability condition of a three-quark system and the spectrum of a tetraquark described b…
