چکیده
Absorptive corrections to the one pion exchange and measurability of the small-x pion structure function at HERA Abstract We compare the absorptive corrections to the one pion exchange in pp → Xn and ep → e ′ Xn reactions. It is shown that the absorption is stronger in the case of pp collision. The difference in strength of the absorption for the pp → Xn and ep → e ′ Xn reactions breaks the factorization peculiar to the pure one pion exchange. We evaluate the emerging model dependence of extraction of the small-x pion structure function from an analysis of the HERA data on the neutron production at physical values of t.

Leading neutron production in ep collisions at HERA
The production of neutrons carrying at least 20% of the proton beam energy (xL > 0.2) in e+p collisions has been studied with the ZEUS detector at HERA for a wide range of Q2, the photon virtuality, from photoproduction to deep inelastic scattering. The neutron-tagged cross section, ep → eXn, is measured relative to the inclusive cross section, ep → eX, thereby reducing the systematic uncertain...

In principle, leading neutrons produced in photoproduction and deep-inelastic scattering at HERA have the potential to determine the pion structure function, the neutron absorptive cross section and the form of the pion flux. To explore this potential we compare theoretical predictions for the xL and pt spectra of leading neutrons, and the Q 2 dependence of the cross section, with the existing ...
متن کاملDeep-Inelastic Electroproduction of Neutrons in the Proton Fragmentation Region
Experiments at HERA looking for deep-inelastic electroproduction of neutrons in the proton fragmentation region are in progress. They are aimed to measure the pion structure function at small Bjorken x. The important condition for such a study is to establish under what kinematical conditions the dominance of the pion-pole graph in the process is guaranteed. We analyse other sources of the lead...

Production of leading neutrons in DIS is usually considered as a tool to measure the pion structure function at small x accessible at HERA. The main obstacle is the lack of reliable evaluations of the absorption corrections, which significantly suppress the cross section. We performed a parameter free calculation within the dipole approach and found the absorption corrections to be nearly as st...
متن کاملReggeon and pion contributions in exclusive diffractive processes at HERA
The contributions of subleading f 2 , ω, a 2 and ρ reggeons to the diffractive structure function F D(3) 2 (x IP , β, Q 2) are estimated. In addition we include the pion exchange which was recently found to be responsible for the violation of the Gottfried Sum Rule. The reggeon and pion contributions lead to a violation of the factor-ization of the diffractive structure function. The diffractiv...
