TL;DR
This paper investigates the production of three high transverse momentum jets from a proton in proton-proton collisions, using perturbative QCD, highlighting its sensitivity to gluon distributions and feasibility at LHC.
Contribution
It introduces a theoretical framework for exclusive diffractive three-jet production in pp collisions within the double-logarithmic approximation of QCD.
Findings
Feasibility of observing three-jet diffractive events at LHC for jets around 5 GeV
Sensitivity of the process to proton unintegrated gluon distribution at small x
Connection to proton light-cone distribution amplitudes
Abstract
We consider the exclusive diffractive dissociation of a proton into three jets with large transverse momenta in the double-logarithmic approximation of perturbative QCD. This process is sensitive to the proton unintegrated gluon distribution at small x and to the proton light-cone distribution amplitudes. According to our estimates, an observation of such processes in the early runs at LHC is feasible for jet transverse momenta of the order of 5 GeV.
