Computation of parton distributions from the quasi-PDF approach at the physical point
Constantia Alexandrou, Simone Bacchio, Krzysztof Cichy +6
We show the first results for parton distribution functions within the proton at the physical pion mass, employing the method of quasi-distributions. In particular, we present the…
Progress in computing parton distribution functions from the quasi-PDF approach
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +5
We discuss the current developments by the European Twisted Mass Collaboration in extracting parton distribution functions from the quasi-PDF approach. We concentrate on the non-pe…
Nonperturbative renormalization of nonlocal quark bilinears for quasi-PDFs on the lattice using an auxiliary field
Jeremy Green, Karl Jansen, Fernanda Steffens
Quasi-PDFs provide a path toward an ab initio calculation of parton distribution functions (PDFs) using lattice QCD. One of the problems faced in calculations of quasi-PDFs is the…
A complete non-perturbative renormalization prescription for quasi-PDFs
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +4
In this work we present, for the first time, the non-perturbative renormalization for the unpolarized, helicity and transversity quasi-PDFs, in an RI' scheme. The proposed prescrip…
Parton Distributions from Lattice QCD with Momentum Smearing
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +4
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 l…
