Query: Double parton scattering with high cross sections   The calculations of the double parton scattering cross sections are
discussed. It is shown that the commonly used factorised formula is valid only
in the limit of low cross sections. The applicability of this approximation is
studied with a more general approach based on the Poisson distribution averaged
over the impact parameter space.
