Preliminary study of the $H$ dibaryon in $N_{f} = 2 + 1$ lattice QCD

AndrÃ© BaiÃ£o Raposo, John Bulava, Jeremy R. Green +9

We present preliminary results on the $I = 0$ , $S = - 2$ $H$ dibaryon in $N_{f} = 2 + 1$ QCD. The calculation is performed with heavier-than-physical quarks ( $m_{I ¨} \approx 280$ MeV) on a…

Three-body study of the $T_{cc} (3875)^{+}$ from lattice QCD

Herzallah Alharazin, AndrÃ© BaiÃ£o Raposo, John Bulava +7

We discuss an ongoing first lattice study of the doubly-charmed tetraquark $T_{cc}^{+}$ (3875) via a three-body approach. We investigate the $D D I ¨ $ system in the $I = 0$ , $C = 2$ sector,…

Extracting scattering amplitudes for arbitrary two-particle systems with one-particle left-hand cuts via lattice QCD

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…
