Production of the MSSM Higgs Bosons at Next Generation Linear $e^{+}{e}^{-}$ Colliders

Abstract

% insert abstract here We study the production of the Higgs bosons predicted in the Minimal Supersymmetric extension of the Standard Model $(h^0,H^0,A^0,H^{\pm })$, with the reactions $e^{+}{e}^{-}\to b\bar{b}{h}^0(H^0,A^0)$, and $e^{+}{e}^{-}\to {\tau }^{-}{\bar{\nu }}_{\tau }{H}^{+},{\tau }^{+}{\nu }_{\tau }{H}^{-}$, using the helicity formalism. We evaluate cross section of $h^0,H^0,A^0$ and $H^{\pm }$ in the limit when $\tan \beta$ is large. The numerical computation is done considering two stages of a possible Next Linear $e^{+}{e}^{-}$ Collider: the first with $\sqrt{s}=500$ $GeV$ and design luminosity 50 $f{b}^{-1}$, and the second with $\sqrt{s}=1$ $TeV$ and luminosity 100-200 $f{b}^{-1}$.
