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…
The determination of by the ALPHA collaboration
Mattia Bruno, Mattia Dalla Brida, Patrick Fritzsch +6
We review the ALPHA collaboration strategy for obtaining the QCD coupling at high scale. In the three-flavor effective theory it avoids the use of perturbation theory at a…
Slow running of the Gradient Flow coupling from 200 MeV to 4 GeV in QCD
Mattia Dalla Brida, Patrick Fritzsch, Tomasz Korzec +3
Using a finite volume Gradient Flow (GF) renormalization scheme with Schrödinger Functional (SF) boundary conditions, we compute the non-perturbative running coupling in the range…
Determination of the QCD -parameter and the accuracy of perturbation theory at high energies
Mattia Dalla Brida, Patrick Fritzsch, Tomasz Korzec +3
We discuss the determination of the strong coupling or equivalently the QCD -parameter. Its determination requires the use of perturb…
The chirally rotated Schrödinger functional: theoretical expectations and perturbative tests
Mattia Dalla Brida, Stefan Sint, Pol Vilaseca
The chirally rotated Schrödinger functional (SF) with massless Wilson-type fermions provides an alternative lattice regularization of the Schrödinger functional (SF), with diffe…
