Transverse Target-spin Asymmetry Associated with Dvcs on the Proton and a Resulting Model-dependent Constraint on the Total Angular Momentum of Quarks in the Nucleon
نویسنده
چکیده
Results are reported on the transverse target-spin asymmetry associated with deeply virtual Compton scattering on the proton, extracted from the data accumulated by the HERMES experiment in the years 2002-2004. By comparing the HERMES results and theoretical predications based on a phenomenological model of generalized parton distributions, a model-dependent constraint on the total angular momentum carried by quarks in the nucleon is obtained.

Measurement of the transverse target-spin asymmetry associated with deeply virtual Compton scattering on the proton
Measurements of deeply virtual Compton scattering (DVCS) made at HERMES using 27.6 GeV e± beams and various internal polarized or unpolarized gaseous targets are discussed. Results are reported on the transverse target-spin asymmetry (TTSA) associated with DVCS, extracted from data accumulated in 2002-2004 with the e beam on a transversely polarized hydrogen target. TTSA amplitudes leading in t...
متن کاملLongitudinal Target-Spin Azimuthal Asymmetry in Deeply-Virtual Compton Scattering
As a generalization of the usual Parton Distribution Functions (PDFs) Generalized Parton Distributions (GPDs), introduced a decade ago, contain additional information about quark and gluon distributions in the plane transverse to the direction of motion of the nucleon. Strong interest in GPDs was triggered by the work of X. Ji who demonstrated that in the forward limit GPDs can give information...
متن کاملMeasurements of Spin Asymmetries for Deeply Virtual Compton Scattering off the Proton using the Extended Maximum Likelihood Method
Generalised Parton Distributions (GPDs) provide a theoretical framework that promises to deliver new information about proton structure. In the impact parameter interpretation, they describe the substructure of the proton in terms of its quark (and gluon) constituents in three dimensions: two transverse spacial dimensions and one longitudinal momentum dimension. Through Ji’s sum rule, they offe...
متن کاملSpin Structure of the Proton and Transverse Momentum Dependent distributions
Transverse Momentum Dependent Distributions (TMDs) describe the spin structure of the proton. At leading twist spin structure of spin-1/2 hadron can be described by 8 TMDs. TMDs reveal three-dimensional distribution of partons inside polarised nucleon. Experimentally these functions can be studied in polarised experiments using Spin Asymmetries in particular Single Spin Asymmetries (SSAs). We d...
متن کاملCan the angular momentum of u-quarks in the nucleon be accessed at Hermes?
We investigate the possibility to acquire information on the generalized parton distribution E and, through a model for E, also on the u-quark total angular momentum Ju by studying deeply virtual Compton scattering and hard exclusive ρ electroproduction on a transversely polarized hydrogen target at Hermes. It is found that a change in Ju from zero to 0.4 corresponds to a 4σ (2σ) difference in ...
