Gluon shadowing in the low x region probed by the LHC

Abstract Starting from an unintegrated gluon distribution which satisfies a ‘unified’ equation which embodies both BFKL and DGLAP behaviour, we compute the shadowing corrections to the integrated gluon in the small x domain that will be accessible at the LHC. The corrections are calculated via the Kovchegov equation, which incorporates the leading ln(1/ x ) triple-pomeron vertex, and are approximately resummed using a simple Pade technique. We find that the shadowing corrections to xg ( x , Q 2 ) are rather small in the HERA domain, but lead to a factor of 2 suppression in the region x ∼10 −6 , Q 2 ∼4 GeV 2 accessible to experiments at the LHC.
