Quasi-PDFs from Twisted mass fermions at the physical point
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +4
We present results for the flavor non-singlet u-d parton distribution functions within the nucleon using the quasi-PDF approach. The lattice calculation is performed by employing t…
Light-cone PDFs from Lattice QCD
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +4
Using the approach proposed a few years ago by X. Ji, it has become feasible to extract parton distribution functions (PDFs) from lattice QCD, a task thought to be extremely diffic…
and of the pion PDF from Lattice QCD with dynamical quark flavours
M. Oehm, C. Alexandrou, M. Constantinou +6
Using Nf=2+1+1 lattice QCD, we determine the fermionic connected contributions to the second and third moment of the pion PDF. Based on gauge configurations from the European Twist…
Flavor symmetry breaking in the sea
J. J. Ethier, W. Melnitchouk, Fernanda Steffens +1
The discovery of a sizeable asymmetry in the and distributions in the proton was one of the more consequential experimental findings in hadron physics last centur…
Transversity parton distribution functions from lattice QCD
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +3
We present the first direct calculation of the transversity parton distribution function within the nucleon from lattice QCD. The calculation is performed using simulations with th…
Reconstruction of light-cone parton distribution functions from lattice QCD simulations at the physical point
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +3
We present the unpolarized and helicity parton distribution functions calculated within lattice QCD simulations using physical values of the light quark mass. Non-perturbative reno…
