Higgs production at hadron colliders: tools



  • HqT: G. Bozzi, S. Catani, D. de Florian, M. Grazzini, Phys. Lett.B 564 (2003) 65 [ hep-ph/0302104], Nucl. Phys. B 737 (2006) 73 [ hep-ph/0508068]; D. de Florian, G. Ferrera, M. Grazzini, D. Tommasini, JHEP 1111 (2011) 064 [arXiv:1109.2109]

    Computes the transverse momentum distribution for Higgs production in pp collisions at NLL+LO and NNLL+NLO accuracy. At NLL+LO the normalization is fixed to the total NLO cross section. At NNLL+NLO the normalization is fixed to the total NNLO cross section.

    HqT2.0 (major update, includes LHAPDF interface, see documentation (PDF))



  • HNNLO: S. Catani, M. Grazzini, Phys. Rev. Lett. 98 (2007) 222002 [ hep-ph/0703012]; M. Grazzini, JHEP 02 (2008) 043, arXiv:0801.3232 [hep-ph]; M. Grazzini, H. Sargsyan, arXiv:1306.4581.

    Parton level Monte Carlo program that computes the cross sections for Higgs production in pp and ppbar collisions up to NNLO in QCD perturbation theory. The present version includes the H->2gamma, H->WW->lnu lnu and H->ZZ->4l decay modes. The program allows the user to apply arbitrary cuts on the momenta of the partons and/or the leptons (photons) produced in the final state, and to easily obtain the desired distributions in the form of bin histograms.

    hnnlo-v2.0 (new version including heavy-quark masses, see documentation (PDF))



  • HRes: D. de Florian, G. Ferrera, M. Grazzini, D. Tommasini, arXiv:1203.6321 [hep-ph]; M. Grazzini, H. Sargsyan, arXiv:1306.4581 [hep-ph].

    Computes fixed cross sections for SM Higgs boson production up to NNLO by consistently including all-order resummation of soft-gluon effects at small transverse momenta up to NNLL. The program retains the full kinematic information on the Higgs boson and its decay products. The present version includes the H->2gamma, H->WW->lnu lnu and H->ZZ->4l decay modes. The program allows the user to apply arbitrary cuts on the Higgs boson and its decay products, and to easily obtain the desired distributions in the form of bin histograms. An interface with ROOT is also provided.

    HRes-v2.3 (new version including heavy-quark masses and dynamic scale, see documentation (PDF))
