Matrix elements of bound states in a finite volume
Andrew W. Jackura
Recently, a framework was developed for studying form factors of two-body states probed with an external current. Finite volume matrix elements that may be computed via lattice QCD…
Consistency checks for two-body finite-volume matrix elements: I. Conserved currents and bound states
Raúl A. Briceño, Maxwell T. Hansen, Andrew W. Jackura
Recently, a framework has been developed to study form factors of two-hadron states probed by an external current. The method is based on relating finite-volume matrix elements, co…
Moments of angular distribution and beam asymmetries in photoproduction at GlueX
V. Mathieu, M. Albaladejo, C. Fernández-Ramírez +4
In the search for exotic mesons, the GlueX collaboration will soon extract moments of the angular distribution. In the perspective of these results, we generalize the formal…
On the Equivalence of Three-Particle Scattering Formalisms
A. W. Jackura, S. M. Dawid, C. Fernández-Ramírez +5
In recent years, different on-shell scattering formalisms have been proposed to be applied to both lattice QCD and infinite volume scattering processes. W…
Three-body scattering: Ladders and Resonances
M. Mikhasenko, Y. Wunderlich, A. Jackura +4
We discuss unitarity constraints on the dynamics of a system of three interacting particles. We show how the short-range interaction that describes three-body resonances can be sep…
Interpretation of the LHCb Pc(4312) Signal
JPAC Collaboration, C. Fernandez-Ramirez, A. Pilloni +6
We study the nature of the new signal reported by LHCb in the J/psi p spectrum. Based on the S-matrix principles, we perform a minimum-bias analysis of the underlying reaction ampl…
