Semi-NLO production of Higgs bosons in the framework of kt-factorization using KMR unintegrated parton distributions

Abstract

The cross-section for the production of the Standard Model Higgs boson has been calculated using a mixture of LO and NLO partonic diagrams and the unintegrated parton distribution functions (UPDF) of the Kimber–Martin–Ryskin (KMR) from the kt-factorization framework. The UPDF are prepared using the phenomenological libraries of Martin–Motylinski–Harland Lang–Thorne (MMHT2014). The results are compared against the existing experimental data from the CMS and the ATLAS collaborations and available pQCD calculation. It is shown that, while the present calculation is in agreement with the experimental data, it is comparable with the pQCD results. It is also concluded that the K-factor approximation is comparable with the semi-NLO kt-factorization predictions.
