A unique signal of excited bosons in dijet data from pp collisions

With this note we would like to draw attention to a possible novel signal of new physics in dijet data at the hadron colliders. Usually it is accepted that almost all exotic models predict that these two jets populate the central (pseudo)rapidity region where y 1,2 ≅ 0. Contrary, the excited bosons...

Description
Summary:With this note we would like to draw attention to a possible novel signal of new physics in dijet data at the hadron colliders. Usually it is accepted that almost all exotic models predict that these two jets populate the central (pseudo)rapidity region where y 1,2 ≅ 0. Contrary, the excited bosons do not contribute into this region, but produce an excess of dijet events over the almost flat QCD background in χ = exp| y 1 − y 2 | away from this region. For the special choice of parameters this could lead to a dip in the centrality ratio distribution over the dijet invariant mass instead of a bump, expected for the most exotic models.
