Abstract

We have used detailed Monte Carlo simulations to study search strategies for Higgs bosons at high energy e/sup +/e/sup /minus// colliders. We extend an earlier study of the minimal single-Higgs-doublet model at a center-of-mass energy of 1 TeV to examine the effects of b-quark tagging and jet counting. It is found that these techniques can increase the signal-to-noise ratio substantially in the mass range around the W mass. In addition, we have studied this model at a center-of-mass energy of 400 GeV and found that an e/sup +/e/sup /minus// collider in this region would be sensitive to a Higgs boson with mass up to twice the Z/degree/ mass. We have also considered a nonminimal two-doublet model for the Higgs sector by extending a study of charged Higgs boson searches to include a mass very close to the mass of the W/sup +-/. We demonstrate that techniques which include b-quark tagging can be utilized to extract a significant signal. In addition, we have examined the prospects for detecting nonminimal neutral Higgs bosons at 1 TeV. We conclude that it would be possible to detect the CP-even and CP-odd neutral Higgs bosons when they are pair-produced in e/sup +/e/sup /minus// annihilation overmore »« less

What [ital e][sup +][ital e[minus]] collider could make a no-lose'' search for minimum supersymmetric standard model Higgs bosons

Journal Article Barger, V; Cheung, K; Phillips, R; ... - Physical Review, D (Particles Fields); (United States)

The lightest [ital CP]-even Higgs boson [ital h] in the minimal supersymmetric standard model (MSSM) has a mass upper bound depending on the top quark and squark masses. An [ital e][sup +][ital e[minus]] collider with enough energy and luminosity to produce [ital h]+[ital Z] at measurable rates up to the maximum [ital h] mass would cover the entire MSSM parameter space if [ital h]+[ital A] production was also searched for. We explore the energy and/or luminosity needed for various top quark and squark masses. For [ital m][sub [ital t]]=150 GeV and a 1 TeV supersymmetric mass scale, a 230 GeVmore »« less

Journal Article Bar-Shalom, S; Wudka, J; Eilam, G; ... - Physical Review, D

The standard model with one extra Higgs doublet may give rise to an enhanced {ital tree-level} flavor-changing-scalar coupling of a neutral Higgs boson to a pair of top-charm quarks. This coupling may drive a large {ital tree-level} effective W{sup +}W{sup {minus}}(ZZ)-Higgs boson-t{bar c} interaction. As a result we find that the reactions e{sup +}e{sup {minus}}{r_arrow}t{bar c}{nu}{sub e}{bar {nu}}{sub e}, t{bar c}e{sup +}e{sup {minus}}, t{bar c}Z and the two rare top decays t{r_arrow}cW{sup +}W{sup {minus}}, t{r_arrow}cZZ become very sensitive probes of such an effective interaction. The most promising ones, e{sup +}e{sup {minus}}{r_arrow}t{bar c}{nu}{sub e}{bar {nu}}{sub e}, t{bar c}e{sup +}e{sup {minus}}, maymore »« less

Charming top decays with a flavor changing neutral Higgs boson and $W W$ at hadron colliders

Journal Article Jain, Rishabh; Kao, Chung - Physical Review. D.

We investigate the prospects for discovering a top quark decaying into one light Higgs boson (h⁰) along with a charm quark (c) in top-quark pair production at the CERN LHC and future hadron colliders. A general two Higgs doublet model is adopted to study the signature of flavor changing neutral Higgs interactions with t → ch⁰, followed by h⁰ → WW* → ℓ⁺ℓ^– + E_T, where h0 is the CP-even Higgs boson and E_T stands for missing transverse energy from neutrinos. We study the discovery potential for this flavor changing neutral Higgs signal and physics background from dominant processes withmore »« less

Many light Higgs bosons in the next-to-minimal supersymmetric model

Journal Article Dermisek, Radovan; Gunion, John - Physical Review. D, Particles Fields

The next-to-minimal supersymmetric model with a light doubletlike CP-odd Higgs boson and small tan{beta} can satisfy all experimental limits on Higgs bosons even with light superpartners. In these scenarios, the two lightest CP-even Higgs bosons, h{sub 1} and h{sub 2}, and the charged Higgs boson, h{sup +}, can all be light enough to be produced at CERN LEP and yet have decays that have not been looked for or are poorly constrained by existing collider experiments. The channel h{sub 1}{yields}a{sub 1}a{sub 1} with a{sub 1}{yields}{tau}{sup +}{tau}{sup -} or 2j is still awaiting LEP constraints for m{sub h{sub 1}}>86 or 82more »« less

Searches for nonminimal Higgs bosons from a virtual /ital Z/ decaying into a muon pair at the SLAC /ital e//sup +/e/sup /minus// storage ring PEP

Journal Article Komamiya, S - Phys. Rev. D; (United States)

Nonminimal neutral Higgs bosons decaying into a muon pair were searched for using the Mark II detector at the SLAC /ital e//sup +/e/sup /minus// collider PEP at /radical//ital s/ =29 GeV. A neutral scalar Higgs boson /ital H//sub /ital s///sup 0/ can be produced accompanied by a pseudoscalar neutral Higgs boson /ital H//sub /ital p///sup 0/ via a virtual /ital Z//sup 0/. If the mass of one of the Higgs bosons is between the muon pair threshold and the kaon pair threshold, it may decay predominantly into a muon pair.
