Background: Measurements of exclusive meson production are a useful tool in the study of hadronic structure. In particular, one can discern the relevant degrees of freedom at different distance scales through these studies. Purpose: To study the transition between nonperturbative and perturbative quantum chromodynamics as the square of four-momentum transfer to the struck proton, -t, is increased. Method: Cross sections for the H1(e,e′π+)n reaction were measured over the -t range of 0.272 to 2…

Deep exclusive π+ electroproduction off the proton at CLAS

The exclusive electroproduction of π+ above the resonance region was studied using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Laboratory by scattering a 6GeV continuous electron beam

Charged pion electroproduction above the resonance region

Background: Above the nucleon resonance region, the N(e,e'π±)N' data cannot be explained by conventional hadronic models. For example, the observed magnitude of the transverse cross section is

An attempt to understand exclusive π+ electroproduction

Hard exclusive π+ electroproduction is investigated within the handbag approach. The prominent role of the pion-pole contribution is demonstrated. It is also shown that the experimental data require

Pion and proton form factors in the regge description of electroproduction p(e, e′π+)n

Electroproduction of π+ above the resonance region is analyzed in the Regge model for π + ρ exchanges. The importance of the roles of the pion and the proton form factors in the process is discussed

Electroproduction of single pions at low E and a measurement of the pion form factor up to Q = 10 G~V~

We report measurements of the electroproduction of single charged pions from hydrogen and deuterium targets for values of epsilon in the range 0.35 < epsilon < 0.45. Data were taken with a hydrogen

Interplay of Hard and Soft Physics in Small $x$ Deep Inelastic Processes

Coherence phenomena, the increase with energy of coherence length and the non-universality of parton structure of the effective Pomeron are explained. New hard phenomena directly calculable in QCD

Transversity in hard exclusive electroproduction of pseudoscalar mesons

Abstract.Estimates for electroproduction of pseudoscalar mesons at small values of skewness are presented. Cross-sections and asymmetries for these processes are calculated within the handbag
