Pomeron intercepts at colliders
Abstract
A method allowing for a direct comparison of data with theoretical predictions is proposed for forward jet and forward pion production at HERA and Mueller-Navelet jets at Tevatron. An application to the determination of the effective Pomeron intercept in the BFKL-LO parametrization from dσ/dx data at HERA leads to a good fit with an intercept, αp = 1.43 ± 0.025(stat.) ± 0.025(syst.), for forward jets and αp = 1.34 ± 0.02(stat.) ± 0.02(syst.), for forward pions. It is less than the value of the pomeron intercept using dijets with large rapidity intervals obtained at Tevatron. We suggest to measure the dependence of the dijet cross-sections as a function of the jet transverse energies as a signal for BFKL pomeron at Tevatron.
