Central production of gluonic and quark-antiquark dijets and background to central production of Higgs boson

Abstract

We discuss exclusive central production of Higgs boson, quark-antiquark and digluon dijets. Several differential distributions are shown and disussed. Irreducible leading-order $b\bar{b}$ background to Higgs production is calculated in several kinematical variables. The signal-to-background ratio is shown and several improvements are suggested by imposing cuts on $b$ ($\bar{b}$) transverse momenta and rapidities. \
