We present new \compass high-statistics measurements of the peripheral production of and pairs in the reactions . For the…
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…
Partial-wave decomposition of the diffractively produced final state at COMPASS
David Spülbeck
One of the prime goals of the COMPASS experiment at CERN is the study of the light meson spectrum, with a particular emphasis on the search for exotic states. We present the first…
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…
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…
