Measurement of dijet cross sections in photoproduction at HERA
The H1 Collaboration(Received: 4 January 2002 / Published online: 12 July 2002 )
Abstract
Dijet cross sections as functions of
several jet observables are measured in
photoproduction using the H1 detector at HERA.
The data sample
comprises
e+p data with an integrated luminosity of 34.9 pb
-1.
Jets
are selected using the inclusive
algorithm
with a minimum transverse energy of
for the leading jet.
The phase space covers longitudinal proton momentum fraction
xp and photon longitudinal momentum fraction
in the ranges
0.05<xp<0.6 and
.
The predictions of next-to-leading order perturbative QCD, including
recent photon and proton parton densities, are found to be compatible
with the data in a wide kinematical range.
