Hard scale dependent gluon density, saturation and forward-forward dijet production at the LHC
arXiv:1409.3822 · doi:10.1103/PhysRevD.91.034021
Abstract
We propose a method to introduce Sudakov effects to the unintegrated gluon density promoting it to be hard scale dependent. The advantage of the approach is that it guarantees that the gluon density is positive definite and that the Sudakov effects cancel on integrated level. As a case study we apply the method to calculate angular correlations and ratio for p+p vs. p+Pb collision in the production of forward-forward dijets.
