Dihadron Transverse-Spin Asymmetries in Muon-Deuteron Deep-Inelastic Scattering
G. D. Alexeev, M. G. Alexeev, C. Alice +168
In 2022, the COMPASS collaboration performed semi-inclusive measurements of deep-inelastic muon-scattering on a transversely polarised deuteron (6LiD) target. From these data, tran…
LHCspin: a Polarized Gas Target for LHC
A. Accardi, A. Bacchetta, L. Barion +90
The goal of the LHCspin project is to develop innovative solutions for measuring the 3D structure of nucleons in high-energy polarized fixed-target collisions at LHC, exploring new…
Spectroscopy of Strange Mesons and First Observation of a Strange Crypto-Exotic State with
G. D. Alexeev, M. G. Alexeev, C. Alice +160
We measured the strange-meson spectrum in the scattering reaction with the COMPASS spectrometer at CERN. Using the world's largest sample…
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…
