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…

First determination of vector and tensor couplings from polarized $π Δ$ photoproduction

Vanamali Shastry, Łukasz Bibrzycki, Vincent Mathieu +7

The couplings between hadrons encode the dynamics of quantum chromodynamics. While many couplings can be calculated from decay widths, in some cases the decays are kinematically fo…

Mechanisms of high energy polarized photoproduction of $π^{-} Δ^{++}$

Vanamali Shastry, Łukasz Bibrzycki, Vincent Mathieu +7

We present an amplitude analysis of high-energy polarized photoproduction of $π^{-} Δ^{++}$ within a Regge exchange framework. A Regge amplitude model incorporating $π$ , $ρ$ , $b_{1}$ , a…
