| Charged Higgs Contribution into $\boldmath t \bar b$-Pair Production in Hadronic Collisions | ||
| Protvino, 2000.-p.14, figs.8, tables 3, refs.:20. | ||
We investigate the charged Higgs boson contribution into $t\bar b$-pair production in $pp$-collisions at LHC. It is shown that due to the $\cz$-boson exchange the total yield of $t\bar b$ is modified significantly for small and large values of $\tan\beta$. However, for the small values of $\tan\beta$ one should expect also the production of right-handed top quark contrary to pure left-handed $t$-quark production through $\wb$-boson exchange only. This fact provides a possibility to separate $\cz$ and $\wb$ contributions by means of the investigations of angular distributions of top decay products. The detailed simulation of the signal and relevant background processes is performed.
