Possible indication to the QCD evolution of double parton distributions?
arXiv:1001.0104 · doi:10.1103/PhysRevD.81.065014
Abstract
For the first time the process-independent parameter of double parton scattering, , has been measured newly in the D0 experiment at the three different resolution scales.If we interpret the measurement as a decrease of the effective cross section with a growth of the resolution scale it can indicate the QCD evolution of double parton distributions.
