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

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 $\mathrm{pp}$ collisions at the CERN Large Hadron Collider. In detail, we compute cross sections and distributions of the reactions $\mathrm{bU}\to {\mathrm{bDH}}^{+}\to \mathrm{bD}{\tau }^{+}{\nu }_{\tau }\oplus \mathrm{c}.\mathrm{c}.\mathrm{}$ and $\mathrm{bU}\to {\mathrm{bDH}}^{+}\to \mathrm{bDt}\overline{b}\to \mathrm{bDb}\overline{b}\mathrm{jj}\oplus \mathrm{c}.\mathrm{c}.\mathrm{}$, 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 former case, charged Higgs boson masses up to about 145 GeV can be covered for both large and small $\tan \beta$’s. In the latter case, charged scalars can be detected for values of $M_{H^{\pm }}$ up to about 500 GeV, especially if $\tan \beta$ is large, and provided that either excellent $b$-tagging performances can be achieved or the high luminosity option becomes available.
