Importance of closed quark loops for lattice QCD studies of tetraquarks
Joshua Berlin, Abdou Abdel-Rehim, Constantia Alexandrou +5
To investigate the light scalar tetraquark candidate (quantum numbers ), a correlation matrix including a variety of two- and four-quark interpolating operator…
Computation of correlation matrices for tetraquark candidates with and flavor structure
Joshua Berlin, Abdou Abdel-Rehim, Constantia Alexandrou +3
The conjecture that several recently observed mesons have a structure, which is not dominated by an ordinary quark-antiquark pair, but by a four-quark structure, is being actively…
Investigation of the tetraquark candidate : technical aspects and preliminary results
Abdou Abdel-Rehim, Constantia Alexandrou, Joshua Berlin +3
We discuss technical aspects and first results of a lattice QCD study of the state. We employ various interpolating operators of quark-antiquark, mesonic molecule, diqua…
Critical behavior and continuum scaling of lattice gauge theories
Oleg Borisenko, Volodymyr Chelnokov, Mario Gravina +1
Three-dimensional lattice gauge theories are studied numerically at finite temperature for = 5, 6, 8, 12, 13, 20 and for =2,4,8. For each model the location of phas…
Phase structure of 3D Z(N) lattice gauge theories at finite temperature: large-N and continuum limits
Oleg Borisenko, Volodymyr Chelnokov, Mario Gravina +1
We study numerically three-dimensional Z(N) lattice gauge theories at finite temperature, for N = 5, 6, 8, 12, 13 and 20 on lattices with temporal extension = 2, 4, 8. For ea…
Phase transitions in the three-dimensional Z(N) models
Oleg Borisenko, Volodymyr Chelnokov, Gennaro Cortese +3
Phase transitions in zero-temperature 3D Z(N) lattice gauge theories are studied. We use a cluster algorithm defined for the dual formulation of the models. We also attempt to expl…
