A Search for Neutral Heavy Vector Gauge
Figure 1: Distribution of dilepton events as a function of invariant mass in 110 pb of data taken at CDF. In this paper we describe a direct search for the Z ′ in its dielectron and dimuon decay modes at CDF. 4 The calorimeters, the Central Tracking Chamber (CTC) and the Muon chambers are the principal detector components used for this search. 5 Data are collected with a multi-level trigger. Th...
متن کاملCP violation in the cubic coupling of neutral gauge bosons.
We investigate the CP violating form factor of the ZZZ and ZZ vertices in the pair production of Z bosons. Useful observables in azimuthal distributions are constructed to probe CP nonconservation which may originate from these vertices. A simple Two Higgs Model of CP violation is used as an illustration. PACS numbers: 11.30.Er, 14.80.Er Typeset using REVTEX
متن کاملSearch for Neutral MSSM Higgs Bosons Decaying to Tau Pairs
We present the results of a search for inclusive production of neutral MSSM Higgs bosons in pp̄ collisions at 1.96 TeV center of mass energy. The data were collected with the CDF II detector at the Tevatron collider at Fermilab, and correspond to an integrated luminosity of 992 pb−1. The search is performed in the di-τ Higgs decay mode. No significant excess of events above the standard model ba...
متن کاملSearch for Supersymmetric Neutral Higgs Bosons at the Tevatron
Recent preliminary results obtained by the CDF and DØ Collaborations on searches for Higgs bosons beyond the Standard Model at Run II of the Tevatron are discussed. The data, corresponding to integrated luminosities of up to 1 fb, are compared to theoretical expectations. No significant excess of signal above the expected background is observed in any of the various final states examined, and s...
متن کاملSearch for new neutral bosons at future colliders ∗
This is a short review of present and future limits on new neutral gauge bosons, in particular on hadrophilic or leptophobic Z ′ s recently proposed to interpret the observed fluctuations of Γ c,b at LEP. Light gauge bosons coupled to lepton number differences or to baryon number are also examples of the model dependence of these bounds. The mixing between the U (1) factors plays an important r...
