A method for identifying H -> tau tau -> e mu pTmiss at the CERN LHC

TL;DR

This paper proposes a method to detect Higgs bosons decaying into tau pairs, specifically through the e mu pTmiss channel, at the LHC, demonstrating its effectiveness in a low-background environment with achievable luminosity.

Contribution

It introduces a new analysis technique for identifying H -> tau tau decays via the e mu pTmiss channel, improving detection prospects at the LHC.

Findings

Higgs detection is feasible with about 60 fb^-1 of data.

The channel provides a low-background environment for Higgs observation.

A No-Lose Theorem for MSSM Higgs detection is restated.

Abstract

Weak boson fusion promises to be a copious source of intermediate mass Higgs bosons at the LHC. The additional very energetic forward jets in these events provide for powerful background suppression tools. We analyze the subsequent H -> tau tau -> e mu pTmiss decay for Higgs boson masses in the 100-150 GeV range. A parton level analysis of the dominant backgrounds demonstrates that this channel allows the observation of H -> tau tau in a low-background environment, yielding a significant Higgs boson signal with an integrated luminosity of order 60 fb^-1 or less, over most of the mass range. We also restate a No-Lose Theorem for observation of at least one of the CP-even neutral Higgs bosons in the MSSM, which requires an integrated luminosity of only 40 fb^-1.
