Standard Higgs Boson Distribution over Q/sub Perpendicular/ Born in Hadron-Hadron Collisions

摘要

The spectrum of standard Higgs H sub 0 boson over transverse moment q/sub perpendicular/ in different, qq-bar; gq(q-bar); gg, channels of production at hadron-hadron collisions is studied. The existence of a qualitative difference between the spectra dsigma/dq/sub perpendicular/ sup 2 of H sub 0 boson and of chi/sub QQ-bar//sup (0)/ (Q=b, t...)-meson, for instance, in a quark channel, is shown. It permits to unambiguously identify H sub 0 by dsigma/dq/sub perpendicular/ sup 2 spectrum in the full range of masses M/sub H/ >or approx. 10 GeV. The influence of the highest orders of perturbation theory on dsigma/dq/sub tr/ sup 2 spectra of H sub 0 bosons is also discussed. (ERA citation 12:042454)
