The ATLAS collaboration has studied signatures of double-parton scattering
in inclusive production of four isolated leptons at proton-proton
collision energy of 8 TeV and in inclusive production of four jets at 7 TeV.
The fraction of events originating from double-parton scattering has been
extracted using dedicated techniques and used to measure the effective
cross section in both...
Double parton scattering (DPS) and double parton distributions (DPDs) are
sensitive to non-trivial colour correlations between partons inside a hadron. At
small inter-parton distances the leading contribution to DPDs is due to a
perturbative splitting mechanism, which makes it possible to calculate DPDs in
perturbation theory in this regime. We compute this contribution at...
We discuss the production mechanism of a new state,
a fully charm tetraquark, discovered recently by the LHCb at
M = 6.9 GeV in the $J/\psi J/\psi$ channel.
Both single parton scattering (SPS) and double parton scattering (DPS)
mechanisms are considered. We calculate the distribution in the invariant
mass of the four-quark system $M_{4c}$ for SPS and DPS production of
$c c \bar c...
A summary of recent results from double-parton scattering studies at CMS will be presented.
Abstract
We present results on two dijets, Wjj, and Zjj production via double parton scattering in pA collisions at the LHC. We perform the analysis at leading and for the case of Zjj next-leading order accuracy with different sets of cuts on jet transverse momenta and accounting for the single parton scattering background. By exploiting the experimental capability to measure the centrality...
