Available in PDF, EPUB and Kindle. Book excerpt: We search for the pair production of doubly charged Higgs particles followed by the lepton-flavor violating decay of each Higgs into electron-and-tau and muon-and-tau pairs using 350 pb{sup -1} of data collected by the CDF II experiment at the Fermilab Tevatron. Separate searches investigate cases where three or four final state leptons are detected, and the limits for each exclusive decay mode reflect the combined results of both searches. Assuming the H{sup {+-}{+-}}{sub L} decays exclusively into like sign electron-and-tau pairs, we set a lower limit on its mass of 114 GeV/c2 at the 95 % confidence level. In the case of exclusive muon-and-tau decays, we set a lower mass limit of 112 GeV/c2 also at the 95% confidence level.

Book excerpt: The authors present the results of a search for doubly-charged Higgs bosons (H{sup {+-}}{sup {+-}}) decaying to dileptons (ll') using {approx} 240 pb{sup -1} of p{bar p} collision data collected by the CDF II experiment at the Fermilab Tevatron. In the search region, given by same-sign ll' mass m{sub ll'}> 80 GeV/c{sup 2} (100 GeV/c{sup 2} for ee channel), they observe no evidence for H{sup {+-}}{sup {+-}} production. They set limits on {sigma}(p{bar p} {yields} H{sup ++}H{sup --} {yields} l{sup +}l'{sup +}l{sup -}l'{sup -}) as a function of the mass of the H{sup {+-}}{sup {+-}} and the chirality of its couplings. Assuming exclusive same-sign dilepton decays, they derive lower mass limits on H{sub L}{sup {+-}}{sup {+-}} of 133 GeV/c{sup 2}, 136 GeV/c{sup 2}, and 115 GeV/c{sup 2} in the ee, {mu}{mu}, and e{mu} channels, respectively, and a lower mass limit of 113 GeV/c{sup 2} on H{sub R}{sup {+-}}{sup {+-}} in the {mu}{mu} channel, all at the 95% confidence level.

This book was released on 2007 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a search for the pair production of doubly-charged Higgs bosons in the process p{bar p} → H++H-- → ?+?+?-?- using the data corresponding to an integrated luminosity of about 1.1 fb-1. This is the complete dataset of RunIIa taken from April 19, 2002 to February 22, 2006 by the D0 experiment at the Fermilab Tevatron Collider. In the absence of significant excess above standard model background, 95% confidence level mass limits of M(H$±±top{L}$) > 150 GeV and M(H$±±top{R}$) > 126.5 GeV are set for left-handed and right-handed doubly-charged Higgs bosons respectively assuming a 100% branching ratio into muons.

No signi cant excess of data over the expected SM background is observed and the results are used to set 95% C.L. limits on the pair production cross section of doubly charged Higgs bosons in the range 90

Available in PDF, EPUB and Kindle. Book excerpt: Doubly-charged Higgs bosons ([Delta][sup --]/[Delta][sup++]) appear in several extensions to the Standard Model and can be relatively light. We review the theoretical motivation for these states and present a study of the discovery reach in future runs of the Fermilab Tevatron for pair-produced doubly-charged Higgs bosons decaying to like-sign lepton pairs. We also comment on the discovery potential at other future colliders. 16 refs., 3 figs., 1 tab.

Book excerpt: Although the standard model of particle physics (SM) is remarkably successful at describing the fundamental particles and their interactions, the mechanism for the breaking of elecroweak symmetry (EWSB) has yet to be confirmed. In the SM, the EWSB sector consists of four scalar fields represented by a single SU(2) complex doublet. Following EWSB, three of the fields are responsible for the generation of the W{sup {+-}} and Z masses, while the fourth is the neutral Higgs boson. At the present time, the Tevatron experiments have set 95% CL exclusion limits on the mass of the SM Higgs boson for the ranges 100 to 109 GeV and 158 to 175 GeV. In addition to these constraints on the SM Higgs boson, the Tevatron experiments have also set limits on neutral and charged Higgs bosons (H{sup {+-}}) in the context of several models beyond the SM. In this review, we discuss searches for charged Higgs bosons performed by the CDF and D0 collaborations at the Fermilab Tevatron in the mass range of 80 to 300 GeV.

Book excerpt: One of the highest priority physics goals for the upgraded Tevatron experiments, CDF and D0, is the search for the Higgs boson. We present the initial results from both experiments, based on 40-90 pb−1 integrated luminosity, of Higgs searches in several final states, including WH and ZH, H --> WW, and doubly-charged Higgs.

Available in PDF, EPUB and Kindle. Book excerpt: We summarize the status of Higgs boson searches at the upgraded Fermilab Tevatron performed by the D0 and CDF collaborations. We report on three categories of searches, namely the search for the Standard Model Higgs boson (p{bar p} {yields} H, WH or ZH, with H {yields} WW* and/or H {yields} b{bar b}), the search for the minimal supersymmetric Higgs boson using p{bar p} {yields} hb{bar b} {yields} b{bar b}b{bar b} and p{bar p} {yields} hX {yields} {tau}{tau}X, and the search for doubly charged Higgs boson.
