Spectroscopy of Strange Mesons and First Observation of a Strange Crypto-Exotic State with $J^P=0^-$

G. D. Alexeev, M.G Alexeev, C. Alice, A. Amoroso et autres

We measured the strange-meson spectrum in the scattering reaction $K^{-}+p \rightarrow K^{-}π^{-}π^{-}+p$ with the COMPASS spectrometer at CERN. Using the world's largest sample of this reaction, we performed a comprehensive partial-wave analysis of the mesonic final state. It substantially extends the strange-meson …

Measurement of the hard exclusive $π^{0}$ muoproduction cross section at COMPASS

G. D. Alexeev, M.G Alexeev, C. Alice, A. Amoroso et autres

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 $Q^2$ ranging from 1 to 8 (GeV/$c$)$^{\rm\, 2}$ and the Bjorken variable $x_{\rm Bj}$ …

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, A. Amoroso et autres

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 $x$, the relative virtual-photon energy $y$ and the fraction of the virtual-photon energy transferred to the final-state hadron …
