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 $I^\cdot I ¨ ^{-}$ and $I^\cdot^{'} I ¨ ^{-}$ pairs in the reactions $I ¨ ^{-} p \to I^\cdot^{(')} I ¨ ^{-} p$ . For the…

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 +160

We measured the strange-meson spectrum in the scattering reaction $K^{-} + p \to K^{-} I ¨ ^{-} I ¨ ^{-} + p$ with the COMPASS spectrometer at CERN. Using the world's largest sample…

Measurement of the hard exclusive $I ¨ ^{0}$ 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…
