Book Description
Our search for a charged Higgs boson is performed with a data sample corresponding to an integrated luminosity of 19.7 ± 0.5 fb-1 collected with the CMS detector in proton-proton collisions at √s=8,TeV. The charged Higgs boson is searched for in top quark decays for m H± m t - m b, and in the direct production pp → t(b)Hsup± /supfor m H± m t - m born The H± → ? ± ? ? and H± → tb decay modes in the final states ? h+jets, ?? h, l+jets, and ll’ (l =e, ?) are considered in the search. No signal is observed and 95% confidence level upper limits are set on the charged Higgs boson production. Furthermore, a model-independent upper limit on the product branching fraction B(t→H±b)B(H±→?±??)=1.2-0.15% is obtained in the mass range m H± = 80–160 GeV, while the upper limit on the cross section times branching fraction ?(pp→t(b)H±)B(H±→ ?±??)=0.38-0.025 pb is set in the mass range m H+ = 180–600 GeV. Here, ?(pp → t(b)H±) stands for the cross section sum ?(pp→t¯(b)H+)+?(pp→t(b¯)H-). Assuming B(H±→tb)=1, an upper limit on ?(pp → t(b)H±) of 2.0–0.13 pb is set for m H± = 180–600 GeV. The combination of all considered decay modes and final states is used to set exclusion limits in the m H±-tan ? parameter space in different MSSM benchmark scenarios.

Book Description
We present a search for a quasi-stable doubly-charged Higgs particle at CDF using the Fermilab Tevatron for √s = 1.96 TeV. The data presented are from approximately 290 pb−1 of integrated luminosity collected using the upgraded Run 2 Collider Detector at Fermilab. These data were taken between February, 2002 and February, 2004. The long-lived decay products of Z's are selected in the central detector region (
