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…

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…

Regge theory in hadron physics

Daniel Winney, Adam P. Szczepaniak

We provide a pedagogical introduction to Regge theory as it pertains to the study of hadrons and their interactions. We clarify the fundamental concepts of analyticity in the compl…

Application of $K \to 3 π$ amplitudes to semileptonic kaon decays

Anshika Bansal, Jack Jenkins, Daniel Winney

We study dispersive representations of nonlocal form factors in $K^{+} \to π^{+} ℓ^{+} ℓ^{-}$ and $K^{+} \to π^{+} ν ν ˉ$ decays, with an aim of improving the theoretical description of…

High-energy $η^{(')} π$ photoproduction and the nature of exotic waves

Gloria Montaña, Vincent Mathieu, Vanamali Shastry +9

The observation of hybrid mesons in photoproduction experiments can provide essential insight into the inner workings of quantum chromodynamics in the strong coupling regime. In pa…
