Abstract
We show that double parton distributions, which are important in describing double parton scattering processes in hadron collisions, can be directly computed from correlations of equal-time nonlocal Euclidean operators on the lattice in the large hadron momentum limit. We demonstrate this by taking the unpolarized color singlet quark double parton distribution as an example, and present a factorization formula connecting the corresponding lightcone and Euclidean correlations. This opens a new possibility of studying multiparton interactions on the Euclidean lattice.
