Colloquium: The shape of hadrons
(2012)This Colloquium addresses the issue of the shape of hadrons and, in particular, that of the proton. The concept of shape in the microcosm is critically examined. Special attention is devoted to properly define the meaning ...

A lattice calculation of parton distributions
(Proceedings of Science (PoS), 2016)We present results for the x dependence of the unpolarized, helicity, and transversity isovector quark distributions in the proton using lattice QCD, employing the method of quasi-distributions proposed by Ji in 2013. ...

Parton distributions from lattice QCD with momentum smearing
(Proceedings of Science (PoS), 2016)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 ...
