Model Which May Be Relevant to the New Lep Events

چکیده
A multi-Higgs model with an extra neutral gauge boson (Z ′) is introduced. One scalar Higgs boson (H 2) in this model decays dominantly into a photon pair. The Z ′ decay to µ + µ − gets a much larger branching ratio than the Z decay to this channel. The ZZ ′ H 2 vertex provides a final state from Z decay resembling the new l + l − γγ events at the LEP. Other promising phenomenology, such as Z → l ¯ lZ ′ is also discussed.

Right-handed Neutral Currents, Families and the LEP l+l−γγ Events
We explore the possibility of having new physics which could account for the llγγ events with Mγγ ≃ 60 GeV recently reported by LEP. We consider models which contain an extra neutral gauge boson (Z ) that couples only to right-handed fermions. The models naturally require at least three quark and lepton families from anomaly cancellation. We find simple realizations of such models that have llγ...
متن کاملHadronic Events at Lep
The hadronic events collected by LEP between 1989 and 2000 have changed dramatically our understanding of QCD, which has now been established as a part of the Standard Model. Still in many sectors (nonperturbative in particular) science analysis needs to be completed, and some new studies are just starting: LEP physics is still the best hadronic physics at accelerators, at least in Europe.
متن کاملThe Historical continuity of the Great Khorasan and Indian subcontinent from the first century to the first half of the seventh century AH; a new approach in historical studies
The contiguity of the Indian subcontinent and Great Khorasan in the Islamic period has connected the political history of these two regions. According to the historical reports, the development of Islam in the subcontinent and formation of Muslims government in India originated in Khorasan political changes. Also, Indians were present in political and military arenas of some Islamic governments...
متن کاملAutomatic Generation of a Multi Agent System for Crisis Management by a Model Driven Approach
Considering the increasing occurrences of unexpected events and the need for pre-crisis planning in order to reduce risks and losses, modeling instant response environments is needed more than ever. Modeling may lead to more careful planning for crisis-response operations, such as team formation, task assignment, and doing the task by teams. A common challenge in this way is that the model shou...
متن کاملThe Z → bb̄ Excess and Top Decay
The apparent excess of Z → bb̄ events at LEP may be an indication of new physics beyond the standard model. However, in either the two-Higgs-doublet model or the minimal supersymmetric standard model, any explanation would lead to an important new decay mode of the top quark and suppresses the t → Wb branching fraction, which goes against what has been observed at the Tevatron. In the two-Higgs-...
