Production of charged Higgs bosons of the minimal supersymmetric standard model inb-quark-initiated processes at the CERN Large Hadron Collider

Abstract

We study integrated and differential rates for the production of charged Higgs bosons $H^\pm$ of the Minimal Supersymmetric Standard Model via b-quark initiated subprocesses in pp collisions at the Large Hadron Collider. In detail, we compute cross sections and distributions of the reactions: $bU \to bDH^+ \to bD\tau^+\nu_\tau\oplus C.C.$ and $bU \to bDH^+ \to bD t\bar b \to bDb\bar b {jj}\oplus C.C.$, for a $H^\pm$ scalar in the intermediate (i.e., $M^\pm<m_t+m_b$) and heavy (i.e., $M^\pm>m_t+m_b$) mass range, respectively (U and D represent generic u- and d-type light quarks). In the first case, a detailed treatment of various possible backgrounds is also given.
