Improved sensitivity to charged Higgs searches in Top quark decays $t\to b{H}^{+}\to b({\tau }^{+}{\nu }_{\tau })$ at the LHC using $\tau$ polarisation and multivariate tecnniques

Ahmed Ali, Fernando Barreiro, Javier Llorente

We present an analysis with improved sensitivity to the light charged Higgs ($m_{H^{+}}<m_t-m_b$) searches in the top quark decays $t\to b{H}^{+}\to b({\tau }^{+}{\nu }_{\tau })+c.c.$ in the…
