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…
Nucleon electromagnetic form factors using lattice simulations at the physical point
Constantia Alexandrou, Martha Constantinou, Kyriakos Hadjiyiannakou +4
We present results for the nucleon electromagnetic form factors using an ensemble of maximally twisted mass clover-improved fermions with pion mass of about 130 MeV. We use multipl…
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…
Nucleon axial form factors using lattice QCD simulations with a physical value of the pion mass
Constantia Alexandrou, Martha Constantinou, Kyriakos Hadjiyiannakou +4
We present results on the nucleon axial and induced pseudo-scalar form factors using an ensemble of two degenerate twisted mass clover-improved fermions generated at the physical v…
Nucleon scalar and tensor charges using lattice QCD simulations at the physical value of the pion mass
C. Alexandrou, M. Constantinou, P. Dimopoulos +9
We present results on the light, strange and charm nucleon scalar and tensor charges from lattice QCD, using simulations with flavors of twisted mass Clover-improved fermio…
Nucleon electromagnetic and axial form factors with N=2 twisted mass fermions at the physical point
Constantia Alexandrou, Martha Constantinou, Kyriakos Hadjiyiannakou +5
We present results for the nucleon electromagnetic and axial form factors using an N=2 twisted mass fermion ensemble with pion mass of about 131 MeV. We use multiple sink-sourc…
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…
