Analytic 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 کاملThe analytic continuation of the high–energy quark–quark scattering amplitude
It is known that the high–energy quark–quark scattering amplitude can be described by the expectation value of two lightlike Wilson lines, running along the classical trajectories of the two colliding particles. Generalizing the results of a previous paper, we give here the general proof that the expectation value of two infinite Wilson lines, forming a certain hyperbolic angle in Minkowski spa...
متن کاملThe analytic continuation of the high – energy parton – parton scattering amplitude with an IR cutoff
The high–energy parton–parton scattering amplitude can be described, in the c.m.s., by the expectation value of two infinite Wilson lines, running along the classical trajectories of the two colliding particles. The above description suffers from IR divergences (typical of 3 + 1 dimensional gauge theories), which can be regularized by considering finite Wilson lines, extending in proper time fr...
متن کاملThe 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...
