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…

Production Effects and Final-state Interactions in $π_{1} \to 3 π$

D. Winney, S. Gonzàlez-Solís, M. Mikhasenko +8

We investigate the $π_{1} (1600)$ signal channel of $3 π$ in the $J^{P C} = 1^{-+} [π π]_{1^{--}} π P$ -wave. This channel has recently been analyzed by the COMPASS collaboration using 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…

Finite-volume analysis of the $H$ -dibaryon including left-hand-cut effects

Arkaitz Rodas, Lin Qiu, César Fernández-Ramírez +4

We implement the finite-volume $N / D$ representation to study two-baryon interactions from lattice QCD data. We include the left-hand cut induced by one-pion exchange in this formal…

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…
