“…16 we show the region in the plane f BB × f W W for m H = 200 GeV that could be excluded at 95% CL from the study of reactions (31) and (32). Notice that for these two reactions the exclusion region closes the gap at f BB = −f W W since the anomalous decay widths H → W + W − (Z 0 Z 0 ) do not vanish along this axis as we have seen in Sec.…”

“…This type of events containing two photons plus missing energy, additional photons or charged fermions represent a signature for several theories involving physics beyond the SM, such as some classes of supersymmetric models 29 and they have been extensively searched for 30,31,32,33 . In the framework of anomalous Higgs couplings presented before, they can also arise from the production of a Higgs boson which subsequently decays in two photons.…”

We review the effects of new effective interactions on the Higgs boson phenomenology. New physics in the electroweak bosonic sector is expected to induce additional interactions between the Higgs doublet field and the electroweak gauge bosons leading to anomalous Higgs couplings as well as to anomalous gauge-boson self-interactions. Using a linearly realized SU (2) L × U (1) Y invariant effective Lagrangian to describe the bosonic sector of the Standard Model, we review the effects of the new effective interactions on the Higgs boson production rates and decay modes. We summarize the results from searches for the new Higgs signatures induced by the anomalous interactions in order to constrain the scale of new physics in particular at CERN LEP and Fermilab Te vatron colliders.

“…Based on the background results of [22] (see also [23]) and eye-ball extrapolations thereof, we estimate that our jet requirements and photon energy/isolation requirements are such that / E min T = 30, 50, 70 GeV is sufficient to eliminate all background for luminosities of L = 100 pb −1 , 2 fb −1 , 30 fb −1 , respectively. Thus, to ascertain the discovery reach of this channel for L = 100 pb −1 , one refers to the σ = 50 fb contour of Fig.…”

Probing gauge-mediated supersymmetry breaking models at the Fermilab Tevatron via delayed decays of the lightest neutralino

We quantitatively explore, in the context of the D0 detector at the Tevatron, three very different techniques for observing delayed decays of the lightest neutralino of a simple gauge-mediated supersymmetry breaking (GMSB) model to photon plus gravitino. It is demonstrated that the delayed-decay signals considered can greatly increase the region of general GMSB parameter space for which supersymmetry can be detected. In the simple class of models considered, the combination of standard supersymmetry signals and delayed-decay signals potentially yields at least one viable signal for nearly all of the theoretically favored parameter space. The importance, for delayed-decay signal detection, of particular detector features and of building a simple photon detector on the roof of the D0 detector building is studied.
