Neutron polarisation transfer, , in photoproduction off the proton

M. Bashkanov, D. P. Watts, S. J. D. Kay +63

We report a first measurement of the double-polarisation observable, , in photoproduction off the proton. The double-polarisation observable represents the t…

Collins and Sivers transverse-spin asymmetries in inclusive muoproduction of mesons

G. D. Alexeev, M. G. Alexeev, C. Alice +188

The production of vector mesons in deep inelastic scattering is an interesting yet scarsely explored channel to study the transverse spin structure of the nucleon and the related p…

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 im…

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 distri…
