Preliminary study of the dibaryon in lattice QCD
André Baião Raposo, John Bulava, Jeremy R. Green +9
We present preliminary results on the , dibaryon in QCD. The calculation is performed with heavier-than-physical quarks ( MeV) on a…
Three-body study of the from lattice QCD
Herzallah Alharazin, André Baião Raposo, John Bulava +7
We discuss an ongoing first lattice study of the doubly-charmed tetraquark (3875) via a three-body approach. We investigate the system in the , sector, w…
Extracting scattering amplitudes for arbitrary two-particle systems with one-particle left-hand cuts via lattice QCD
André Baião Raposo, Raúl A Briceño, Maxwell T Hansen +1
We derive a general formalism that relates the spectrum of two-particle systems in a finite volume to physical scattering amplitudes, taking into account the presence of any left-h…
Finite-volume scattering on the left-hand cut
André Baião Raposo, Maxwell T. Hansen
The two-particle finite-volume scattering formalism derived by Lüscher and generalized in many subsequent works does not hold for energies far enough below the two-particle thresho…
The Lüscher scattering formalism on the -channel cut
André Baião Raposo, Maxwell T. Hansen
The Lüscher scattering formalism, the standard approach for relating the discrete finite-volume energy spectrum to two-to-two scattering amplitudes, fails when analytically continu…
