Double production in pion-nucleon scattering at COMPASS

G. D. Alexeev, M. G. Alexeev, A. Amoroso +191

We present the study of the production of double mesons using COMPASS data collected with a 190 GeV/ beam scattering off NH, Al and W targets. Kinematic dist…

Measurement of -weighted Sivers asymmetries in leptoproduction of hadrons

M. G. Alexeev, G. D. Alexeev, A. Amoroso +209

The transverse spin asymmetries measured in semi-inclusive leptoproduction of hadrons, when weighted with the hadron transverse momentum , allow for the extraction of importan…

Search for exclusive photoproduction of Z(3900) at COMPASS

C. Adolph, R. Akhunzyanov, M. G. Alexeev +205

A search for the exclusive production of the hadron by virtual photons has been performed in the channel . The data cover…

Spin Density Matrix Elements in Exclusive Meson Muoproduction

G. D. Alexeev, M. G. Alexeev, C. Alice +186

We report on a measurement of Spin Density Matrix Elements (SDMEs) in hard exclusive meson muoproduction at COMPASS using 160~GeV/ polarised and beams…

The exotic meson with and its decay into

M. G. Alexeev, G. D. Alexeev, A. Amoroso +192

We study the spin-exotic amplitude in single-diffractive dissociation of 190 GeV pions into using a hydrogen target and confirm the $π_1(1600)…

Sivers asymmetry extracted in SIDIS at the hard scale of the Drell-Yan process at COMPASS

C. Adolph, M. Aghasyan, R. Akhunzyanov +223

Proton transverse-spin azimuthal asymmetries are extracted from the COMPASS 2010 semi-inclusive hadron measurements in deep inelastic muon-nucleon scattering in those four regions…
