Theory:

Multiparton pdfs and factorization in multiparton interaction (M. Diehl, A.Schaefer)

A QCD Analysis of Double Parton Scattering: Color Correlations, Interference Effects and Evolution (A. V. Manohar, W. J. Waalewijn).

Double parton interaction (B.Block, Y.Dokshitzer, M.Strickman)

MC development:

MPI model in Sherpa

DYPSY (Gustafson, Loennblad)

EPOS

MC Tuning:

Epos LHC tune There are many new observables measured by the LHC experiments which should be used for tuning MPI, among those underlying event at forward rapidity (CMS) and forward-backward correlations (ATLAS), forward energy flow by TOTEM.
