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…

First determination of vector and tensor couplings from polarized $I ¨ I^$ photoproduction

Vanamali Shastry, Åukasz 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 $I ¨ ^{-} I^^{++}$

Vanamali Shastry, Åukasz Bibrzycki, Vincent Mathieu +7

We present an amplitude analysis of high-energy polarized photoproduction of $I ¨ ^{-} I^^{++}$ within a Regge exchange framework. A Regge amplitude model incorporating $I ¨ $ , $I ¨ $ , $b_1…

High-energy $I^\cdot^{(')} I ¨ $ photoproduction and the nature of exotic waves

Gloria MontaÃ±a, 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…

Nonperturbative aspects of the electromagnetic pion form factor at high energies

Joint Physics Analysis Center, :, K. Quirion +10

The structure of hadronic form factors at high energies and their deviations from perturbative quantum chromodynamics provide insight on nonperturbative dynamics. Using an approach…
