Investigating the role of tetraquark operators in lattice QCD studies of the and resonances
Andrew D. Hanlon, Daniel Darvish, Sarah Skinner +7
The role of tetraquark operators in studying the isodoublet strange and isovector nonstrange scalar mesons in lattice QCD is examined using an ensemble with $m_Ï\a…
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…
Di-nucleons do not form bound states at heavy pion mass
John Bulava, M. A. Clark, Arjun S. Gambhir +16
We perform a high-statistics lattice QCD calculation of the low-energy two-nucleon scattering amplitudes. In order to address discrepancies in the literature, the calculation is pe…
Relating categorical dimensions in topology and symplectic geometry
Andrew Hanlon, Jeff Hicks, Oleg Lazarev
We study several notions of dimension for (pre-)triangulated categories naturally arising from topology and symplectic geometry. We prove new bounds on these dimensions and raise s…
Two- and three-meson scattering amplitudes with physical quark masses from lattice QCD
Sebastian M. Dawid, Zachary T. Draper, Andrew D. Hanlon +5
We study systems of two and three mesons composed of pions and kaons at maximal isospin using four CLS ensembles with fm, including one with approximately physica…
QCD predictions for physical multimeson scattering amplitudes
Sebastian M. Dawid, Zachary T. Draper, Andrew D. Hanlon +5
We use lattice QCD calculations of the finite-volume spectra of systems of two and three mesons to determine, for the first time, three-particle scattering amplitudes with physical…
