Evaluation of the PDF uncertainty for the light pseudoscalar Higgs production in the process gg → bbA, A → μ + μ − and analysis of di-muon events accompanied by jets in 8 TeV CMS data

The PDF uncertainty for the light pseudoscalar Higgs production in gluon-gluon fusion, gg → bbA as a function of mA was evaluated in the mass region 12-70 GeV. MSTW2008NLO90CL, CT10NLO and NNPDF23 parton distribution function sets were used. Di-muon and jets data was analysed in order to provide information about different particles from which decays two muons emerge. Tools which were mainly used are ROOT and APFEL Web.
