This talk provides a review of the latest results on the theory of Double Parton Scattering
Double Parton Scattering with the ATLAS Experiment
A wide programme of studies of Double Parton Scattering (DPS) processes is performed with the ATLAS detector at LHC. DPS processes are studied not only with charm and beauty hadrons , but also with jets and W bosons in the final state topology. The talk will review the measurements of several properties of DPS processes in these...
We present recent results on Double Parton Scattering (DPS) studies using data collected during Run 1 and Run 2 of the LHC with the CMS experiment. Double parton scattering is investigated in several final states including vector bosons and multi-jets. Measurements of observables designed to highlight the DPS contribution are shown and compared to MC predictions from models based on multiple...
The production cross-section of J/ψ pairs in the forward region is measured using a data sample of pp col-
lisions collected by the LHCb experiment at a centre-of-mass energy of 13 TeV .
Differential cross-sections are presented as functions of several kinematic variables of the J/ψ
pair are measured and compared to theoretical predictions.
LHCb observed the associated production of bottomonia and open charm hadrons in pp collisions at centre of mass energies of 7 and 8 TeV is observed. Production
cross-sections are measured for Υ(1S)D0 and Υ(1S)D+ pairs in the forward region.
Measurements of the production of J/ψ mesons accompanied by open charm, and of pairs of open charm hadrons are shown.
I will review the status of theory studies of Double Parton Scatterings (DPS) using associated production of quarkonia at colliders. This includes $J/\psi+J/\psi$, $\Upsilon+\Upsilon$, $J/\psi+\Upsilon$, $J/\psi+W$, $J/\psi+Z$, $\Upsilon+D$ and $J/\psi+D$. Where relevant, I will discuss the impact of QCD corrections to Single Parton Scatterings which can affect the extraction of the DPS yield....
Phenomena of multiple-parton interaction (MPI) have become very
essential for precise description of high-energy proton-proton
collisions in the ongoing LHC era.
Some time ago we have proposed and discussed double open charm meson
production $pp \to D D \!\; X$ as a potentially one of the best reaction
to study hard double-parton scattering effects at the LHC.
This conclusion was further...
