Differential Cross-Sections for Higgs Production

Differential cross sections for Higgs boson production at tevatron collider energies.

The transverse momentum Q(T) distribution is computed for inclusive Higgs boson production at sqrt[S]=1.96 TeV. We include all-orders resummation of large logarithms associated with emission of soft gluons at small Q(T). We provide results for Higgs boson and Z* masses from M(Z) to 200 GeV. The relatively hard transverse momentum distribution for Higgs boson production suggests possibilities fo...

Higgs-Boson production at hadron colliders: differential cross sections through next-to-next-to-leading order.

We present a calculation of the fully differential cross section for Higgs-boson production in the gluon fusion channel through next-to-next-to-leading order (NNLO) in perturbative QCD. We apply the method introduced in Phys. Rev. D 69, 076010 (2004)] to compute double real emission corrections. Our calculation permits arbitrary cuts on the final state in the reaction hh-->H+X. It can easily be...

Differential Cross Sections for Top-pair and Single-top Production

Measurement of differential tt̄ production cross sections in pp̄ collisions

Measurement of differential t ¯ t production cross sections in p ¯ p collisions The production of top quark-antiquark pair events in p¯ p collisions at √ s = 1.96 TeV is studied as a function of the transverse momentum and absolute value of the rapidity of the top quarks as well as of the invariant mass of the t ¯ t pair. We select events containing an isolated lepton, a large imbalance in tran...

Charm production cross-sections

During the years 1994–97, the emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS of 27 GeV average neutrino energy. In total about 100, 000 charged-current neutrino interactions with at least one identified muon were located in the nuclear emulsion target and fully reconstructed, using newly developed automatic scanning systems. Charmed particles w...
