The transverse energy distribution in hadron-lead collisions

The transverse energy cross-sectiondσ/dE T has been measured in the pseudorapidity region 0.6<η<2.4 for hadron-lead collisions at 200 GeV/c incident hadron momentum. TheE T distribution extends to 40 GeV, which is twice the kinematic limit forp-p collisions at the same incident beam momentum. The distribution ofE T is found to shift towards low pseudorapidities with increasing total transverse energy.
