We consider chargino-neutralino production, $\tilde{\chi}_2^0 \tilde{\chi}_1^\pm \to (h \tilde{\chi}_1^0)(W^\pm \tilde{\chi}_1^0)$, which results in Higgs boson final states that subsequently decay (inclusively) to leptons (either…

We study the prospects for observing exotic decays of the Standard Model Higgs boson $h$ into light beyond the Standard Model scalars $a$ with mass $m_{a} \lesssim m_{h}/2$ in the single Higgs and Higgs pair production channels at the high…

A prospective analysis for the search of the Standard Model (SM) Higgs boson with the CMS detector is presented in the context of the early LHC data. The aim is to establish an analysis strategy for inclusive production of the Higgs boson…

The electroweak sector of the Minimal Supersymmetric Standard Model (MSSM) - neutralinos, charginos and sleptons - remains relatively weakly constrained at the LHC due in part to the small production cross sections of these particles. In…

We analyze the decays $\{h^0,H^0,A^0\}\to \bar{s}b$ within two Higgs Doublet Models with Natural Flavor Conservation (2HDM) type I and II. It is found that the Higgs bosons decay into bottom-strange can lead to a branching ratio in the…

A search for a charged Higgs boson (H+) in ttbar decays is presented, where one of the top quarks decays via t->H+b, followed by H+->two jets (csbar). The other top quark decays to Wb, where the W boson then decays into a lepton (e/mu) and…

We assess the potential of detecting a charged Higgs boson of the MSSM at the LHC via its decays into a chargino and a neutralino. We focus our attention on the region of parameter space with $m_{H^{\pm}} > m_t$ and $3 \lsim tan(beta) \lsim…

For a heavy Higgs boson above the $t\bar t$ threshold we consider three decay modes that could compete with decay to $t\bar t$, even in the alignment limit of a 2-Higgs doublet model. The decays $H\to AZ$, $ Z'Z'$ and $\tau'\tau'$ show that…
