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…
Looking at the gluon moment of the nucleon with dynamical twisted mass fermions
Constantia Alexandrou, Vincent Drach, Kyriakos Hadjiyiannakou +3
To understand the structure of hadrons it is important to know the PDF of their constituents, the quarks and gluons. In our work we aim to compute the first moment of the gluon PDF…
Disconnected quark loop contributions to nucleon observables in lattice QCD
A. Abdel-Rehim, C. Alexandrou, M. Constantinou +5
We perform a high statistics calculation of disconnected fermion loops on Graphics Processing Units for a range of nucleon matrix elements extracted using lattice QCD. The isoscala…
Strangeness of the nucleon from Lattice Quantum Chromodynamics
Constantia Alexandrou, Martha Constantinou, Simon Dinter +5
We present a non-perturbative calculation of the strangeness of the nucleon within the framework of lattice QCD. This observable is known to be an important cornerstone to in…
Evaluation of disconnected quark loops for hadron structure using GPUs
C. Alexandrou, M. Constantinou, V. Drach +5
A number of stochastic methods developed for the calculation of fermion loops are investigated and compared, in particular with respect to their efficiency when implemented on Grap…
