Collins and Sivers asymmetries in muonproduction of pions and kaons off transversely polarised proton

C. Adolph, R. Akhunzyanov, M. G. Alexeev +205

Measurements of the Collins and Sivers asymmetries for charged pions and charged and neutral kaons produced in semi-inclusive deep-inelastic scattering of high energy muons off tra…

Odd and Even Partial Waves of $η π^{-}$ and $η^{'} π^{-}$ in $π^{-} p \to η^{(')} π^{-} p$ at $191 GeV / c$

C. Adolph, R. Akhunzyanov, M. G. Alexeev +205

Exclusive production of $η π^{-}$ and $η^{'} π^{-}$ has been studied with a $191 GeV / c$ $π^{-}$ beam impinging on a hydrogen target at COMPASS (CERN). Partial-wave analyses reveal d…

Spin alignment and violation of the OZI rule in exclusive $ω$ and $ϕ$ production in pp collisions

C. Adolph, R. Akhunzyanov, M. G. Alexeev +206

Exclusive production of the isoscalar vector mesons $ω$ and $ϕ$ is measured with a 190 GeV $/ c$ proton beam impinging on a liquid hydrogen target. Cross section ratios are determine…

Measurement of the charged-pion polarisability

C. Adolph, R. Akhunzyanov, M. G. Alexeev +210

The COMPASS collaboration at CERN has investigated pion Compton scattering, $π^{-} γ \to π^{-} γ$ , at centre-of-mass energy below 3.5 pion masses. The process is embedded in the r…
