Elements of a theory for multiparton interactions in QCD
We perform a detailed investigation of multiple hard interactions in
hadron-hadron collisions. We discuss the space-time, spin and color structure
of multiple interactions, classify different contributions according to their
power behavior and provide several elements required for establishing all-order
factorization. This also allows us to analyze the structure of Sudakov
logarithms in double hard scattering. We show how multiparton distributions can
be constrained by lattice calculations, by connecting them with generalized
parton distributions, and by calculating their behavior at large transverse
parton momenta.Comment: 144 pages, 42 figures. v3: small corrections as published in erratum.
