In this work we continue our effort to explore a recent proposal, which allows light-cone distributions to be extracted from purely spatial correlations, being thus accessible to lattice methods. In order to test the feasibility of this method, we present our latest results from a twisted mass lattice calculation of the flavor non-singlet momentum, helicity and transversity distributions of the nucleon. Furthermore, we apply a newly proposed momentum improved smearing, which has the potential to reach higher nucleon momenta as required for a safe matching procedure to the physical distribution functions. © Copyright owned by the author(s).

Gluon propagator without lattice Gribov copies on a finer lattice
Alexandrou, Constantia; De Forcrand, Ph; Follana, E. (2002)We extend our study of the gluon propagator in quenched lattice QCD using the Laplacian gauge to a finer lattice. We verify the existence of a pole mass as we take the continuum limit and deduce a value of ∼600-30 +150 MeV ...

Transient kinetic study of the reaction of CH4 and C2H6 with the lattice oxygen of Li+-doped TiO2 catalyst
Efstathiou, Angelos M.; Papageorgiou, D.; Verykios, Xenophon E. (1993)A transient kinetic study of the reaction of CH4/He and C2H6/He with the lattice oxygen of Li+-doped TiO2 catalyst was performed. The results obtained indicate that lattice oxygen species must be considered as oxidation ...
