Measurement of the hard exclusive muoproduction cross section at COMPASS

G. D. Alexeev, M. G. Alexeev, C. Alice +169

A new and detailed measurement of the cross section for hard exclusive neutral-pion muoproduction on the proton was performed in a wide kinematic region, with the photon virtuality…

Multiplicities of positive and negative pions, kaons and unidentified hadrons from deep-inelastic scattering of muons off a liquid hydrogen target

G. D. Alexeev, M. G. Alexeev, C. Alice +166

The multiplicities of positive and negative pions, kaons and unidentified hadrons produced in deep-inelastic scattering are measured in bins of the Bjorken scaling variable , th…
