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 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 chi = exp|y_1-y_2| away from this region.
