“…This expression assumes that the number of parton-parton interactions per collision is distributed according to Poisson statistics [6], and that the two scatterings are distinguishable [7]. Previous measurements of e have come from c 1997 American Institute of Physics 1 2 the AFS [3], UA2 [4], and CDF [5] experiments. The most signi cant measurement, e =12.1 +10:7 5:4 mb, was obtained from the CDF analysis of four jet events.…”

“…The most sensitive v ariable, S [5], is the azimuthal angle between the transverse momentum (p T ) v ectors of the two best-balancing pairs (photon + 1 jet, and dijet). In SP events, momentum conservation biases S towards 180 o , while in DP events the S distribution is atter.…”

“…The most signi cant measurement, e =12.1 +10:7 5:4 mb, was obtained from the CDF analysis of four jet events. Based on a model which assumes that the proton is a uniformly dense ball of partons and the measured inelastic pp cross section at p s=1.8 TeV, the expected value is e =11 mb [5]. CDF has recently reported a measurement o f e using a photon + 3 jets nal state [8,9].…”

“…We restrict ourselves to this simple form (2.5) regarding it as the first estimate for the DPS contribution. The CDF [20] and D0 [21] measurements give σ eff ≃ 15 mb, that constitutes roughly 20% of the total (elastic + inelastic) pp cross section at the Tevatron energy.…”

Correlations in J/ψ pair production as SPS versus DPS discriminators

We focus on the problem of disentangling the single (SPS) and double (DPS) parton scattering modes in the production of J/ψ pairs at the LHC conditions. Our analysis is based on comparing the shapes of the differential cross sections and on studying their behavior under imposing kinematical cuts. On the SPS side, we consider the leading-order O(α 4 s ) contribution with radiative corrections (taken into account in the framework of the k t -factorization approach) and the subleading O(α 6 s ) contribution from pseudo-diffractive gluon-gluon scattering represented by one gluon exchange and two gluon exchange mechanisms. We come to the conclusion that disentangling the SPS and DPS modes is rather difficult on the basis of azimuthal correlations, while the rapidity difference looks more promising, provided the acceptance of the experimental detectors has enough rapidity coverage.

“…The splash of research activity around MPI in recent years [4,5] has been stimulated by the experimental evidence for double parton scattering (DPS) in the processes producing two independently identified hard particles. Such processes have been observed in pp and pp collisions for the final states containing four jets, γ + 3 jets, and W + 2 jets by AFS [6], UA2 [7], CDF [8,9], D0 [10][11][12], AT-LAS [13], and CMS [14] Collaborations. The data on double J/ψ production [15], and single J/ψ production as a function of the event multiplicity [16] can also be successfully interpreted using DPS [17][18][19][20] and MPI models, respectively.…”
