Description
The HL-LHC program will be sensitive to significantly smaller effects
of BSM physics than probed so far. This implies that the quantitative understanding of non-perturbative Standard Model "backgrounds" has to be improved correspondingly. In this context Multiple Parton Interactions (MPIs) are a major concern. Theory efforts to improve their understanding focus on the simplest case, Double Parton Interactions, which are parameterized by Double Parton Distributions (DPDs) [1]. Jianhui Zhang
will present a talk on LaMET evaluations of DPDs [2], see also [3], while I plan to present some general introduction, analytic results [4] and lattice results for DPD moments [5].
