First Observation of an Exotic Reggeon

G. D. Alexeev, M. G. Alexeev, C. Alice +180

We present new \compass high-statistics measurements of the peripheral production of $η π^{-}$ and $η^{'} π^{-}$ pairs in the reactions $π^{-} p \to η^{(')} π^{-} p$ . For the first t…

Measurement of the cross section for hard exclusive $π^{0}$ leptoproduction

M. G. Alexeev, G. D. Alexeev, A. Amoroso +199

We report on a measurement of hard exclusive $π^{0}$ muoproduction on the proton by COMPASS using 160 GeV/ $c$ polarised $μ^{+}$ and $μ^{-}$ beams of the CERN SPS impinging on a liquid hy…

Light isovector resonances in $π^{-} p \to π^{-} π^{-} π^{+} p$ at 190 GeV/ $c$

M. Aghasyan, M. G. Alexeev, G. D. Alexeev +221

We have performed the most comprehensive resonance-model fit of $π^{-} π^{-} π^{+}$ states using the results of our previously published partial-wave analysis (PWA) of a large data set of…
