Hadron-Hadron Interactions from Lattice QCD: The -resonance
Markus Werner, Martin Ueding, Christopher Helmes +8
We present an investigation of the Rho-meson from Nf=2+1+1 flavour lattice QCD. The calculation is performed based on gauge configuration ensembles produced by the ETM collaboratio…
Meson-meson scattering lengths at maximum isospin from lattice QCD
Christopher Helmes, Christian Jost, Bastian Knippschild +5
We summarize our lattice QCD determinations of the pion-pion, pion-kaon and kaon-kaon s-wave scattering lengths at maximal isospin with a particular focus on the extrapolation to t…
Topological susceptibility and meson mass from lattice QCD at the physical point
Petros Dimopoulos, Christopher Helmes, Christian Jost +8
In this paper we explore the computation of topological susceptibility and meson mass in flavor QCD using lattice techniques with physical value of the pion mass as we…
Hadron-Hadron Interactions from Lattice QCD: Scattering Length
Christopher Helmes, Christian Jost, Bastian Knippschild +5
In this paper we report on results for the s-wave scattering length of the - system in the channel from Lattice QCD. The calculation is based on gauge con…
The meson at the physical point with Wilson twisted mass fermions
Christopher Helmes, Bastian Knippschild, Bartosz Kostrzewa +6
We present results for the eta prime meson and the topological susceptibility in two flavour lattice QCD. The results are obtained using Wilson twisted mass fermions at maximal twi…
Isospin-0 scattering from twisted mass lattice QCD
L. Liu, S. Bacchio, P. Dimopoulos +11

Christopher Helmes, Christian Jost, Bastian Knippschild +4
We present results for the interaction of two kaons at maximal isospin. The calculation is based on 2+1+1 flavour gauge configurations generated by the ETM Collaboration (ETMC) fea…
First Physics Results at the Physical Pion Mass from Wilson Twisted Mass Fermions at Maximal Twist
ETM Collaboration, A. Abdel-Rehim, C. Alexandrou +20
We present physics results from simulations of QCD using dynamical Wilson twisted mass fermions at the physical value of the pion mass. These simulations were enabled by…
Hadron-Hadron Interactions from Lattice QCD: isospin-2 scattering length
C. Helmes, C. Jost, B. Knippschild +7
We present results for the scattering length using twisted mass lattice QCD for three values of the lattice spacing and a range of pion mass values. Due to t…
Pi-Pi Scattering with Nf=2+1+1 Twisted Mass Fermions
Christopher Helmes, Christian Jost, Bastian Knippschild +3
Pi-Pi scattering is investigated for the first time for Nf=2+1+1 dynamical quark flavours using Wilson twisted mass fermions. Lüscher's finite size method is used to relate energy…
