Title: Running with triplets: How slepton masses change with doubly-charged Higgs bosons

Abstract

We examine the slepton masses of SUSYLR models and how they change due to the presence of light doubly-charged Higgs bosons. We discover that the measurement of the slepton masses could bound and even predict the value of the third generation Yukawa coupling of leptons to the SU(2){sub R} triplets. We also consider the unification prospects for this model with the addition of left-handed, B-L=0 triplets--a model we call the triplet extended supersymmetric standard model (TESSM)

  • Doubly charged Higgs bosons, H{sup {+-}}{sup {+-}}, are being searched for in the Tevatron experiments. The most recent search by the D0 Collaboration seeks three muons ({mu}{sup {+-}}{mu}{sup {+-}}{mu}{sup {+-}}), which are assumed to originate from the pair-production process, qq{yields}H{sup ++}H{sup --}, followed by the decay H{sup {+-}}{sup {+-}}{yields}{mu}{sup {+-}}{mu}{sup {+-}}. In this three-lepton (3l) channel there are six distinct signatures for l=e or {mu}. In the context of the Higgs Triplet Model, we quantify the dependence of the event numbers for the 3l channels on the parameters of the neutrino mass matrix. It is also shown that the inclusionmore » of the production mechanism qq{sup '}{yields}H{sup {+-}}{sup {+-}}H{sup {+-}}, followed by the decay H{sup {+-}}{yields}l{sup {+-}}{nu}, would significantly increase the discovery potential in these channels. We then provide perspectives on the production of these channels at the Tevatron and LHC.« less
  • The rate for the lepton-number-violating decay K{sup {plus_minus}}{r_arrow}{pi}{sup {minus_plus}}{mu}{sup {plus_minus}}{mu}{sup {plus_minus}} is calculated in a model which incorporates doubly charged Higgs bosons. We find that for reasonable values of the parameters the decay branching ratio may be as large as 2{times}10{sup {minus}16}. Although this is a discouragingly small number, it is of the same order of magnitude as the rate mediated by massive Majorana neutrinos. {copyright} {ital 1997} {ital The American Physical Society}
  • The authors search for pair production of doubly charged Higgs particles (H{sup {+-}{+-}}) followed by decays into electron-tau (e{tau}) and muon-tau ({mu}{tau}) pairs using a data set corresponding to an integrated luminosity of 350 pb{sup -1} collected from {bar p}p collisions at {radical}s = 1.96 TeV by the CDF II experiment. They search separately for cases where three or four final-state leptons are detected, and then combine the results into limits for each exclusive flavor decay mode of the H{sup {+-}{+-}}. Assuming 100% branching ratios of the H{sup {+-}{+-}} to left-handed e{tau} ({mu}{tau}) pairs, they set an H{sup {+-}{+-}} lowermore » mass limit of 114 (112) GeV/c{sup 2} at the 95% confidence level (C.L.).« less
  • We present a search for long-lived doubly-charged Higgs bosons (H{sup {+-}{+-}}), with signatures of high ionization energy loss and muon-like penetration. We use 292 pb{sup -1} of data collected in p-{bar p} collisions at {radical}s = 1.96 TeV by the CDF II detector at the Fermilab Tevatron. Observing no evidence of long-lived doubly-charged particle production, we exclude H{sub L}{sup {+-}{+-}} and H{sub R}{sup {+-}{+-}} bosons with masses below 133 GeV/c{sup 2} and 109 GeV/c{sup 2}, respectively. In the degenerate case we exclude H{sup {+-}{+-}} mass below 146 GeV/c{sup 2}. All limits are quoted at the 95% confidence level.
