Parton distributions from lattice data: the nonsinglet case
Krzysztof Cichy, Luigi Del Debbio, Tommaso Giani
We revise the relation between Parton Distribution Functions (PDFs) and matrix elements computable from lattice QCD, focusing on the quasi-Parton Distribution Functions (qPDFs) app…

Strong dynamics with matter in multiple representations: SU(4) gauge theory with fundamental and sextet fermions
Guido Cossu, Luigi Del Debbio, Marco Panero +1
We present a non-perturbative lattice study of SU(4) gauge theory with two flavors of fermions in the fundamental representation and two in the two-index antisymmetric representati…

Non perturbative physics from NSPT: renormalons, the gluon condensate and all that
Luigi Del Debbio, Francesco Di Renzo, Gianluca Filaci
Numerical Stochastic Perturbation Theory (NSPT) enables very high order computations in Lattice Gauge Theories. We report on the determination of the gluon condensate from lattice…
