Description
The talk is based on the results of our publications [1]. First of all we show that
the contribution from double parton scattering to the inclusive production of heavy
meson pairs is comparable with the conventional single parton scattering mechanism
at the LHC energy. Then we focus on the problem of disentangling the single (SPS)
and double (DPS) parton scattering modes in the production of J/ pairs at the LHC
conditions. Our analysis is based on comparing the shapes of the differential cross
sections and on studing their behavior under imposing kinematical cuts. 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 accsptence of the experimental detectors has enough rapidity coverage.
