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…

Antiproton over proton and K over K multiplicity ratios at high in DIS

M. G. Alexeev, G. D. Alexeev, A. Amoroso +195

The over p multiplicity ratio is measured in deep-inelastic scattering for the first time using (anti-) protons carrying a large fraction of the virtual-photon energ…

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…

Light isovector resonances in at 190 GeV/

M. Aghasyan, M. G. Alexeev, G. D. Alexeev +221

We have performed the most comprehensive resonance-model fit of states using the results of our previously published partial-wave analysis (PWA) of a large data set…

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…

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…
