Recently there has been much interest in the pair production of
quarkonia. The production of quarkonium pairs is expected to receive
an important contribution from double parton scattering (DPS) processes.
There remain a number of open problems, especially with the CMS and ATLAS data.
The effective cross sections $\sigma_{\rm eff}$ found
from empirical analyses are about a factor $2.5$ smaller...
The origin of long-range rapidity correlations observed in p-p and p-Pb collisions at LHC is one of the outstanding questions of strong interactions. The leading theoretical explanations of the so-called "ridge" effect are hydrodynamics and the initial state dynamics, with the latter often described in the Color Glass Condensate (CGC) framework. CGC-based calculations have successfully...
The talk will report on the most recent results obtained by the CMS experiment on multiple partonic interactions in heavy-ion collisions
In this talk I will summarize results of our studies of hard MPI effects in heavy flavour sector in pp-collisions at the LHC. During last two years we extend our previous studies of double-parton scattering (DPS) in double charm production to simultaneous production of charm and bottom as well as to double bottom production. We have also analyzed in this context associated production of charm...
The talk will present an overview of the most recent results obtained by the TOTEM and CMS experiments on the so-called forward physics
