Recent Results on Light-Meson Spectroscopy from COMPASS
Stefan Wallner
The main goal of the spectroscopy program at COMPASS is to explore the light-meson spectrum below about in diffractive production. Our flagship channel is the d…
Longitudinal double-spin asymmetry and spin-dependent structure function of the proton at small values of and
M. Aghasyan, R. Akhunzyanov, M. G. Alexeev +225
We present a precise measurement of the proton longitudinal double-spin asymmetry and the proton spin-dependent structure function at photon virtualitie…
Transverse-momentum-dependent Multiplicities of Charged Hadrons in Muon-Deuteron Deep Inelastic Scattering
M. Aghasyan, R. Akhunzyanov, M. G. Alexeev +227
A semi-inclusive measurement of charged hadron multiplicities in deep inelastic muon scattering off an isoscalar target was performed using data collected by the COMPASS Collaborat…
Search for muoproduction of at COMPASS and indication of a new state
M. Aghasyan, R. Akhunzyanov, M. G. Alexeev +224
We have searched for exclusive production of exotic charmonia in the reaction using COMPASS data collected with incoming muons of…
First measurement of transverse-spin-dependent azimuthal asymmetries in the Drell-Yan process
Aghasyan, R. Akhunzyanov, M. G. Alexeev +216
The first measurement of transverse-spin-dependent azimuthal asymmetries in the pion-induced Drell-Yan (DY) process is reported. We use the CERN SPS 190 GeV/, beam and a…
First measurement of the Sivers asymmetry for gluons from SIDIS data
C. Adolph, M. Aghasyan, R. Akhunzyanov +223
The Sivers function describes the correlation between the transverse spin of a nucleon and the transverse motion of its partons. It was extracted from measurements of the azimuthal…
