Search for charged Higgs bosons and measurement of D < # 4 D in quark and lepton # avour identi " ed events at LEP
نویسنده
چکیده
A search for pair produced charged Higgs bosons was performed on the high energy data collected by DELPHI at LEP2. All three major "nal states, smsm, cssm and cscs were searched for. The analyses used a combination of event shape variables, di-jet masses and jet #avour tagging. The jet #avours were identi"ed by using life time tagging and particle identi"cation based on the RICH detector complemented by ionisation energy loss measurements. A similar type of jet #avour tagging was also used in extracting the D< #4 D element of the Cabibbo}Kobayashi}Maskawa (CKM) matrix in hadronic decays of the WB boson. ( 1999 Elsevier Science B.V.

N ov 1 99 6 STANDARD HIGGS BOSON SEARCHES AT LEP 2
The process ee → bbff with f = ν, or f = charged lepton or f = u, d quark is analyzed in the range of LEP 2 energies. In the near future LEP 2 will represent a unique opportunity for a direct search of a Higgs boson of mass > 65GeV. The whole emphasis has been put on a self consistent study of the standard Higgs boson properties. Indeed there is the actual possibility of testing a calculation w...
متن کاملStrangephilic Higgs Bosons in the MSSM
We suggest a new CPX-derived scenario for the search of strangephilic MSSM Higgs bosons at the Tevatron and the LHC, in which all neutral and charged Higgs bosons decay predominantly into pairs of strange quarks and into a strange and a charm quark, respectively. The proposed scenario is realized within a particular region of the MSSM parameter space and requires large values of tanβ, where thr...
متن کاملHiggs Physics: from LEP to a Future Linear Collider
New preliminary combined results from the LEP experiments on searches for the Higgs boson beyond the Standard Model are presented. The new determination of the top quark mass at the Tevatron in 2004 influences the interpretations of the LEP results in both, the Standard Model, and the Minimal Supersymmetric extension of the Standard Model. Higgs boson physics will also be a major research area ...
متن کاملHiggsBounds 2.0.0: Confronting neutral and charged Higgs sector predictions with exclusion bounds from LEP and the Tevatron
HiggsBounds 2.0.0 is a computer code which tests both neutral and charged Higgs sectors of arbitrary models against the current exclusion bounds from the Higgs searches at LEP and the Tevatron. As input, it requires a selection of model predictions, such as Higgs masses, branching ratios, effective couplings and total decay widths. HiggsBounds 2.0.0 then uses the expected and observed topologic...
متن کاملBeyond the Standard Model searches with top quarks at D 0
Due to its high mass and short lifetime, the top quark plays an important role in checking the Standard Model of particle physics. In this report, we present a variety of searches for physics beyond the Standard Model, involving top quarks, at the D0 detector at the Fermilab Tevatron collider. Specifically, we present searches in top quark pair production, single top quark production and top qu...
