THE LHC EXCESS OF FOUR-LEPTON EVENTS INTERPRETED AS HIGGS-BOSON SIGNAL: BACKGROUND FROM DOUBLE DRELL-YAN PROCESS?

We construct a simple model of the Double Drell-Yan Process (DDYP) for proton-proton collisions and investigate its possible contribution to the background for the Higgs-boson searches at the LHC. We demonstrate that under the assumption of the predominance of short range, O(0.1) fm, transverse-plane correlations of quark-antiquark pairs within the proton, this contribution becomes important and may even explain the observed excess of the four-lepton events at the LHC - the events interpreted as originating from the Higgs-boson decays: H -> ZZ* -> 4l and H -> WW* -> 2l2 nu.
