Progress in Simulations with Twisted Mass Fermions at the Physical Point

Abdel-Rehim, A., Alexandrou, C., Dimopoulos, P. et al.

Understand

In this contribution, results from $N_f=2$ lattice QCD simulations at one lattice spacing using twisted mass fermions with a clover term at the physical pion mass are presented.

  • The mass splitting between charged and neutral pions (including the disconnected contribution) is shown to be around $20(20)~\mathrm{MeV}$.
  • Further, a first measurement using the clover twisted mass action of the average momentum fraction of the pion is given.
  • Finally, an analysis of pseudoscalar meson masses and decay constants is presented involving linear interpolations in strange and charm quark masses.
