We present results for the isospin-0 $\pi\pi$ s-wave scattering length calculated in twisted mass lattice QCD. We use three $N_f = 2$ ensembles with unitary pion mass at its physical value, 240~MeV and 330~MeV respectively. We also use a large set of

We present results for the isospin-0 $\pi\pi$ s-wave scattering length calculated with Osterwalder-Seiler valence quarks on Wilson twisted mass gauge configurations. We use three $N_f = 2$ ensembles with unitary (valence) pion mass at its physical va

We present first results on the $\rho$ resonance parameters obtained with $N_f=2+1+1$ Wilson twisted mass fermions at maximal twist. Using ensembles of the ETM collaboration, we provide results for two values of the lattice spacing and a range of pio

We present physics results from simulations of QCD using $N_f = 2$ dynamical Wilson twisted mass fermions at the physical value of the pion mass. These simulations were enabled by the addition of the clover term to the twisted mass quark action. We s

We present results for the $I=2$ $\pi\pi$ scattering length using $N_f=2+1+1$ twisted mass lattice QCD for three values of the lattice spacing and a range of pion mass values. Due to the use of Laplacian Heaviside smearing our statistical errors are

Topological susceptibility and η′ meson mass from Nf = 2 lattice QCD at the physical point. Physical review.

In this paper we explore the computation of topological susceptibility and η' meson mass in Nf = 2 flavor QCD using lattice techniques with a physical value of the pion mass as well as larger pion mass values. We observe that the physical point can

In this paper, we report on results for the s-wave scattering length of the π−K system in the I=3/2 channel from Nf=2+1+1 lattice QCD. The calculation is based on gauge configurations generated by the European Twisted Mass Collaboration with pion

We discuss the status of our project concerned with the determination of hadron-hadron interactions from lattice Quantum Chromodynamics. In addition, we discuss our optimisation efforts for current and future supercomputer architectures.
