A search for H$^{+}$ and H$^{++}$ Higgs boson with the CMS detector

TL;DR

This paper reports on searches for exotic doubly charged and singly charged Higgs bosons using CMS data from 2010-2011, aiming to discover new particles beyond the Standard Model.

Contribution

It provides the first experimental search results for H$^{++}$ and H$^{+}$ Higgs bosons in specific decay channels at the LHC.

Findings

No significant excess observed over background

Limits set on the masses of H$^{++}$ and H$^{+}$

Constraints improve upon previous bounds

Abstract

We present results from a search for an exotic Higgs boson in the channel H$^{++}$ $\rightarrow ~\ell^{+}\ell^{+}$ with the CMS detector using data accumulated in the 2010 & 2011 running of the LHC at $\sqrt{s}$ = 7 TeV. We also present results from a search for a charged Higgs boson in $t\bar{t}$ decays in the channel H$^{+}$ $\rightarrow$ $\tau\nu$
