Effects of Multi-Parton Interactions in Jet Quenching in Heavy-Ion Collisions

We perform the first systematic study of the effects of multi-parton interactions (MPI's) in the context of jet quenching in heavy-ion collisions with the jet quenching model JEWEL. We use the simple MPI model of PYTHIA 6, on which JEWEL is based. We find negligible effects on all observables except jet-hadron and Z-hadron correlations, which show a moderate enhancement at large distances. More detailed analysis at parton level reveals that, in heavy-ion collisions, the MPI contribution to jets is suppressed by quenching effects.

Unequal rapidity correlators in the dilute limit of JIMWLK

We study unequal rapidity correlators in the stochastic Langevin picture of Jalilian-Marian - Iancu - McLerran - Weigert - Leonidov - Kovner (JIMWLK) evolution in the Color Glass Condensate effective field theory. By separately evolving the Wilson lines in the direct and complex conjugate amplitudes, we use the formalism to study two-particle production at large rapidity separations. We show that the evolution between the rapidities of the two produced particles can be expressed as a linear equation, even in the full nonlinear limit. We also show how the Langevin formalism for two-particle correlations reduces to a BFKL picture in the dilute limit and in momentum space, providing an interpretation of BFKL evolution as a stochastic process for color charges.

We study unequal rapidity correlators in the stochastic Langevin picture of Jalilian-Marian-Iancu-McLerran-Weigert-Leonidov-Kovner (JIMWLK) evolution in the Color Glass Condensate effective field theory. We discuss a diagrammatic interpretation of the long-range correlators.
