A mechanism for the Double-Spin Asymmetry in Electromagnetic ρ Production at HERMES
نویسنده
چکیده
We calculate the contribution of meson and pomeron exchanges to the double-spin asymmetry in ρ-meson electromagnetic production at HERMES energies. We show that the observed double-spin asymmetries, which are large, can be explained by the interference between the natural parity f2-secondary Reggeon and the unnatural parity anomalous f1 exchanges.

Double - spin asymmetries in the cross section of ρ 0 and φ production at intermediate energies
Double-spin asymmetries in the cross section of electroproduction of ρ and φ mesons on the proton and deuteron are measured at the HERMES experiment. The photoabsorption asymmetry in exclusive ρ electroproduction on the proton exhibits a positive tendency. This is consistent with theoretical predictions that the exchange of an object with unnatural parity contributes to exclusive ρ electroprodu...
متن کاملDIS structure functions and the double-spin asymmetry in ρ electroproduction within a Regge approach
The proton, neutron and deuteron structure functions F2(x,Q 2) and g1(x,Q 2), measured at intermediate Q2, are analyzed within a Regge approach. This analysis serves to fix the parameters of this scheme which are then used to calculate, in a unified Regge approach, the properties of ρ0 meson electroproduction on the proton and the deuteron. In this way, the double-spin asymmetry observed at HER...
متن کاملQuark correlations and single-spin asymmetries
Many hadron production reactions give rise to significant ⊥ single-spin asymmetries (SSA) which persist at high energies. For example, hyperons produced in hadronic collisions typically show a large polarization perpendicular to the production plane. More recently, the HERMES collaboration found a significant SSA (left-right asymmetry in the transverse momentum distribution of the produced meso...
متن کاملKinematical contributions to the transverse asymmetry in semi-inclusive DIS
In the studies of semi-inclusive charged and neutral pion production off a longitudinally polarized protons, the HERMES collaboration has observed a single target-spin asymmetry (SSA) [1]. This asymmetry could either result from twist-3 chiral-odd effects [2,3] and/or could be a reflection of the Collins effect [4]. Which of the two is relevant is an open issue. For a further understanding of “...
متن کاملDouble-spin cosφ asymmetry in semi-inclusive electroproduction
We consider the double-spin cosφ asymmetry for pion electroproduction in semi-inclusive deep inelastic scattering of longitudinally polarized leptons off longitudinally polarized protons. We estimate the size of the asymmetry in the approximation where all twist-3 interaction-dependent distribution and fragmentation functions are set to zero. In that approximation at HERMES kinematics a sizable...
