Nucleon generalized form factors with twisted mass fermions
C. Alexandrou, M. Constantinou, V. Drach +3
We present results on the nucleon form factors, momentum fraction and helicity moment for and twisted mass fermions for a number of lattice volumes and lattice…
The quark contents of the nucleon and their implication for dark matter search
C. Alexandrou, M. Constantinou, V. Drach +5
We present results concerning the light and strange quark contents of the nucleon using flavours of maximally twisted mass fermions. The corresponding -terms are cas…
Recent developments in the tmLQCD software suite
Abdou Abdel-Rehim, Florian Burger, Alber Deuzeman +4
We present an overview of recent developments in the tmLQCD software suite. We summarise the features of the code, including actions and operators implemented. In particular, we di…
A first look at maximally twisted mass lattice QCD calculations at the physical point
A. Abdel-Rehim, Ph. Boucaud, N. Carrasco +15
In this contribution, a first look at simulations using maximally twisted mass Wilson fermions at the physical point is presented. A lattice action including clover and twisted mas…
Implementation of the twisted mass fermion operator in the QUDA library
Alexei Strelchenko, Constantia Alexandrou, Giannis Koutsou +1
We discuss an extension of the QUDA library for the Wilson twisted mass operator. A performance analysis is presented for both degenerate and non-degenerate flavor doublets. The de…
Investigation of light and heavy tetraquark candidates using lattice QCD
Marc Wagner, Abdou Abdel-Rehim, Constantia Alexandrou +5
We review the status of an ongoing long-term lattice investigation of the spectrum and structure of tetraquark candidates. We focus on the light scalar meson . First step…
