Longitudinal double-spin asymmetry A1p and spin-dependent structure function g1p of the proton at small values of x and Q2

M. Aghasyan, M. Alexeev, G. D. Alexeev, A. Amoroso et autres

We present a precise measurement of the proton longitudinal double-spin asymmetry A 1 p and the proton spin-dependent structure function g 1 p at photon virtualities 0.006 ( GeV / c ) 2 < Q 2 < 1 ( GeV / c …

First measurement of the Sivers asymmetry for gluons using SIDIS data

C. Adolph, M. Aghasyan, R. Akhunzyanov, M. Alexeev et autres

The Sivers function describes the correlation between the transverse spin of a nucleon and the transverse motion of its partons. For quarks, it was studied in previous measurements of the azimuthal asymmetry of hadrons produced in semi-inclusive deep inelastic scattering of leptons …

Multiplicities of charged pions and charged hadrons from deep-inelastic scattering of muons off an isoscalar target

C. Adolph, M. Aghasyan, R. Akhunzyanov, G.D. Alexeev et autres

Multiplicities of charged pions and charged hadrons produced in deep-inelastic scattering were measured in three-dimensional bins of the Bjorken scaling variable x , the relative virtual-photon energy y and the relative hadron energy z . Data were obtained by the COMPASS Collaboration …

Longitudinal double spin asymmetries in single hadron quasi-real photoproduction at high $p_T$

COMPASS Collaboration, C. Adolph, R. Akhunzyanov, M. Alexeev et autres

We measured the longitudinal double spin asymmetries $A_{LL}$ for single hadron muo-production off protons and deuterons at photon virtuality $Q^2$ < 1(GeV/$\it c$)$^2$ for transverse hadron momenta $p_T$ in the range 0.7 GeV/$\it c$ to 4 GeV/$\it c$ . They were determined …
