Consistency checks for two-body finite-volume matrix elements: II. Perturbative systems / Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Jackura, Andrew W. (Jefferson Lab ; Old Dominion U.)
Using the general formalism presented in Refs. [1,2], we study the finite-volume effects for the $\mathbf{2}+\mathcal{J}\to\mathbf{2}$ matrix element of an external current coupled to a two-particle state of identical scalars with perturbative interactions. [...]

Consistency checks for two-body finite-volume matrix elements: Conserved currents and bound states / Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Jackura, Andrew W. (Jefferson Lab ; Old Dominion U.)
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, computed using numerical lattice QCD, to the corresponding infinite-volume observables. [...]

Moments of angular distribution and beam asymmetries in $\eta\pi^0$ photoproduction at GlueX / Mathieu, V. (Jefferson Lab ; Madrid U.) ; Albaladejo, M. (Jefferson Lab) ; Fernández-Ramírez, C. (Mexico U., ICN) ; Jackura, A.W. (Indiana U., CEEM ; Indiana U.) ; Mikhasenko, M. (CERN) ; Pilloni, A. (ECT, Trento ; Fond. Bruno Kessler, Trento ; INFN, Genoa) ; Szczepaniak, A.P. (Jefferson Lab ; Indiana U., CEEM ; Indiana U.) /JPAC Collaboration
In the search for exotic mesons, the GlueX collaboration will soon extract moments of the $\eta\pi^0$ angular distribution. In the perspective of these results, we generalize the formalism of moment extraction to the case in which the two mesons are produced with a linearly polarized beam, and build a model for the reaction $\vec \gamma p \to \eta \pi^0 p$.

On the Equivalence of Three-Particle Scattering Formalisms / Jackura, A.W. (Indiana U. ; Indiana U., CEEM) ; Dawid, S.M. (Indiana U. ; Indiana U., CEEM) ; Fernández-Ramírez, C. (Mexico U., ICN) ; Mathieu, V. (Madrid U.) ; Mikhasenko, M. (CERN) ; Pilloni, A. (INFN, Genoa ; ECT, Trento) ; Sharpe, S.R. (Washington U., Seattle) ; Szczepaniak, A.P. (Indiana U. ; Indiana U., CEEM ; Jefferson Lab)
In recent years, different on-shell $\mathbf{3}\to\mathbf{3}$ scattering formalisms have been proposed to be applied to both lattice QCD and infinite volume scattering processes. We prove that the formulation in the infinite volume presented by Hansen and Sharpe in Phys.~Rev.~D92, 114509 (2015) and subsequently Brice\~no, Hansen, and Sharpe in Phys.~Rev.~D95, 074510 (2017) can be recovered from the $B$-matrix representation, derived on the basis of $S$-matrix unitarity, presented by Mai {\em et al.} in Eur.~Phys.~J.~A53, 177 (2017) and Jackura {\em et al.} in Eur.~Phys.~J.~C79, 56 (2019).
