The High Energy Behavior of the Forward Scattering Parameters—An Amplitude Analysis Update
Utilizing the most recent experimental data, we reanalyze high energy p̄p and pp data, using the asymptotic amplitude analysis, under the assumption that we have reached ‘asymptopia’. This analysis gives strong evidence for a log (s/s0) dependence at current energies and not log(s/s0), and also demonstrates that odderons are not necessary to explain the experimental data. Work partially supporte...
متن کاملA Theorem on the Real Part of the High-energy Scattering Amplitude near the Forward Direction
We show that if for fixed negative (physical) square of the momentum transfer t, the differential cross-section dσ dt tends to zero and if the total cross-section tends to infinity, when the energy goes to infinity, the real part of the even signature amplitude cannot have a constant sign near t = 0. ∗) URA 14-36 du CNRS, associée à L’Ecole Normale Supérieure de Lyon et à l’Université de Savoie...
متن کاملAnalytic Amplitude Models for Forward Scattering
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 the fits of many possible parameterizations to a large sample of data, we developed and used a set of quantitative indicators measuring statistical quality of the fits over and beyond the typical criterion of the χ2/d...
متن کاملHigh - energy spin effects and structure of elastic scattering amplitude
A behavior of imaginary and real parts of the high-energy elastic hadron scattering amplitude is examined in the diffraction region. It is shown that the interference between Coulomb and hadronic scattering at small momentum transfers and especially in the region of diffractive minimum can bring some information about the structure of the hadron spin-non-flip amplitude.
متن کاملOn near forward high energy scattering in QCD
We consider elastic quark-quark scattering at high energy and fixed transferred momentum. Performing factorization of soft gluon exchanges into Wilson lines vacuum expectation values and studying their properties, we find that the asymptotics of the scattering amplitude is controlled by the renormalization properties of the so called cross singularities of Wilson loops. Using this fact, we eval...
