Pion-pole contribution to HLbL from twisted mass lattice QCD at the physical point
Sebastian Burri, Constantia Alexandrou, Simone Bacchio +13
We report on our computation of the pion transition form factor from twisted mass lattice QCD in order to determine the numerically dominant light…
Lattice QCD results for the topological up-quark mass contribution: too small to rescue the solution to the strong CP problem
Constantia Alexandrou, Jacob Finkenrath, Lena Funcke +4
A vanishing Yukawa coupling of the up quark could in principle solve the strong CP problem. To render this solution consistent with current algebra results, the up quark must recei…
Gradient flow scale-setting with Wilson-clover twisted-mass fermions
Constantia Alexandrou, Simone Bacchio, Georg Bergner +12
We present a determination of the gradient flow scales , and in isosymmetric QCD, making use of the gauge ensembles produced by the Extended Twisted Mas…
Determination of the light, strange and charm quark masses using twisted mass fermions
C. Alexandrou, S. Bacchio, G. Bergner +23
We present results for the light, strange and charm quark masses using twisted mass fermion ensembles at three values of the lattice spacing, including two ensembles si…
Quark and gluon momentum fractions in the pion from lattice QCD
Constantia Alexandrou, Simone Bacchio, Georg Bergner +11
We perform the first full decomposition of the pion momentum into its gluon and quark contributions. We employ an ensemble generated by the Extended Twisted Mass Collaboration with…
Quark masses using twisted mass fermion gauge ensembles
C. Alexandrou, S. Bacchio, G. Bergner +24
We present a calculation of the up, down, strange and charm quark masses performed within the lattice QCD framework. We use the twisted mass fermion action and carry out simulation…
Ratio of kaon and pion leptonic decay constants with Wilson-clover twisted-mass fermions
C. Alexandrou, S. Bacchio, G. Bergner +12
We present a determination of the ratio of kaon and pion leptonic decay constants in isosymmetric QCD (isoQCD), , making use of the gauge ensembles produced by the Exten…
