Production of Scalar Higgs and Pseudoscalar Higgs in Multi-Higgs Doublet Models at γγ Colliders
We present the effects of heavy CP-even (H) and CP-odd (A) Higgs bosons on the production cross section of the process γγ → tt at the energy around the mass poles of the Higgs bosons. It is found that the interference between H and A with the small mass gap, as well as the ones between Higgs bosons and the continuum, contributes to the cross section, if the photon beams are polarized and if we ...
متن کاملDifferential 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...
متن کاملGluon mini-jet production in nuclear collisions at high energies
We show explicitly that the leading soft gluon pT distribution, predicted by Kovner, McLerran, and Weigert after solving classical Yang-Mills equations, can be understood in terms of conventional QCD perturbation theory. We also demonstrate that the key logarithm in their result represents the logarithm in DGLAP evolution equations. PACS numbers: 12.38.Bx, 12.38.Mh, 24.85.+p Typeset using REVTEX
متن کاملMultiphoton production at high energies in the standard model. I.
We examine multiphoton production in the electroweak sector of the Standard Model in the high energy limit using the equivalence theorem in combination with spinor helicity techniques. We obtain recursion relations for currents consisting of a charged scalar, spinor, or vector line that radiates n photons. Closed form solutions to these recursion relations for arbitrary n are presented for the ...
متن کاملNLO correction to one - particle inclusive production at high energies
Next-to-leading order correction to the one-particle inclusive cross section in the framework of high energy factorization is calculated. Numerical results for midrapidity region are compared with predictions of conventional calculations based on collinear factorization. e-mail: [email protected]
