Production of charged Higgs bosons of the Minimal Supersymmetric Standard Model in b-quark initiated processes at the 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: $bU\to bD{H}^{+}\to bD{\tau }^{+}{\nu }_{\tau }\oplus C.C.$ and $bU\to bD{H}^{+}\to bDt\bar{b}\to bDb\bar{b}jj\oplus C.C.$, 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.
