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…
QCD in the chiral SU(3) limit from baryon masses on Lattice QCD ensembles
Matthias F. M. Lutz, Yonggoo Heo, Renwick J. Hudspith
The baryon masses on CLS ensembles are used to determine the LEC that characterize QCD in the flavor-SU(3) limit with vanishing up, down, and strange quark masses. Here we reevalua…
Precise Omega baryons from lattice QCD
Renwick J. Hudspith, Matthias F. M. Lutz, Daniel Mohler
In this paper we determine the masses of and -baryon ground states using lattice QCD. We utilise Wilson-clover ensembles with…
The thermal photon emissivity at the QCD chiral crossover from imaginary momentum correlators
Ardit Krasniqi, Marco Cè, Tim Harris +3
The thermal photon emissivity at the QCD chiral crossover is investigated using imaginary momentum correlators. These have been measured on a newly generated latti…
