## Target mass effects in parton quasi-distributions

We study the impact of non-zero (and apparently large) value of the nucleon mass

*M*on the shape of parton quasi-distributions Q(y,p_{3}), in particular on its change with the change of the nucleon momentum p_{3}. We observe that the usual target-mass corrections induced by the*M*-dependence of the twist-2 operators are rather small. Moreover, we show that within the framework based on parametrizations by transverse momentum dependent distribution functions (TMDs) these corrections are canceled by higher-twist contributions. Lastly, we identify a novel source of kinematic target-mass dependence of TMDs and build models corrected for such dependence. We findmore »
