Exotic mesons in the continuum from a nonperturbatively-tuned heavy quark action
R. J. Hudspith, Daniel Mohler, M. Stolz
In this work we predict the masses and binding energies of two exotic-meson candidates using Lattice QCD, namely the and . We use a relativistic heavy-quar…
as a precision test of a new four flavor Domain Wall Fermion action
Renwick J. Hudspith, Nicolas Garron, Zack Hall +12
We present a new set of lattice QCD ensembles with four flavors of smeared Möbius Domain Wall Fermions with good chiral symmetry and small fifth-dimensional extent. A modest amount…
Probing how bright the quark-gluon plasma glows in lattice QCD
Ardit Krasniqi, Marco Cè, Tim Harris +2
Determining the spectrum of photons emitted by the quark-gluon plasma non-perturbatively remains an open computational challenge. In this letter we calculate two moments of that sp…
Quark mass dependence of doubly heavy tetraquark binding
W. G. Parrott, B. Colquhoun, A. Francis +3
The existence of bound doubly heavy tetraquark states was confirmed by the recent LHCb discovery of the doubly charmed , less than 1 MeV below the meson pair threshold. Oth…
Improved analysis of strong-interaction-stable doubly-bottom tetraquarks on the lattice
B. Colquhoun, A. Francis, R. J. Hudspith +3
We update earlier lattice results for the binding energies of the flavor antitriplet of strong-interaction-stable doubly bottom, tetraquarks, employing an extended sink c…
Hot QCD matter around the chiral crossover: a lattice study with -improved Wilson fermions
Ardit Krasniqi, Marco Cè, Renwick J. Hudspith +1
Using lattice QCD simulations with -improved Wilson quarks and physical up, down and strange quark masses, we investigate the properties of thermal QCD matter at the temperat…
