ATLAS DISCOVERY POTENTIAL FOR A HEAVY CHARGED HIGGS BOSON. [electronic resource]
The sensitivity of the ATLAS detector to the discovery of a heavy charged Higgs boson is presented. Assuming a heavy SUSY spectrum, the most promising channels above the top quark mass are H{sup {+-}} → tb and h{sup {+-}} → τ{sup {+-}}ν{sub τ} which provide coverage in the low and high tan β regions...

| Summary: | The sensitivity of the ATLAS detector to the discovery of a heavy charged Higgs boson is presented. Assuming a heavy SUSY spectrum, the most promising channels above the top quark mass are H{sup {+-}} → tb and h{sup {+-}} → τ{sup {+-}}ν{sub τ} which provide coverage in the low and high tan β regions up to ≈ 600 GeV. The achievable precisions on the charged Higgs mass and tan β determination are also discussed. The H{sup {+-}} → W{sup {+-}}h° channel, though restricted to a small MSSM parameter space, shows a viable signal in NMSSM where the parameter space is less constrained. The observation of the channel H⁻ → {tau}{sub L}⁻ ν{sub {tau}} + c.c. may constitute a distinctive evidence for models with singlet neutrinos in large extra dimensions. |
