چکیده
A four generation supersymmetric model is proposed, in which the Tevatron “top-quark” events are reinterpreted as the production of t′ which decays dominantly to bW. In this model, mt ≃ mW , and t → t̃χ̃01, with t̃ → cχ̃01. This decay chain, which rarely produces a hard isolated lepton, would have been missed in all previous top quark searches. A narrow region of the model parameter space exists which cannot yet be ruled out by present data. This model predicts a rich spectrum of new physics which can be probed at LEP-II and the Tevatron.

Characterizations of Slant Ruled Surfaces in the Euclidean 3-space
In this study, we give the relationships between the conical curvatures of ruled surfaces generated by the unit vectors of the ruling, central normal and central tangent of a ruled surface in the Euclidean 3-space E^3. We obtain differential equations characterizing slant ruled surfaces and if the reference ruled surface is a slant ruled surface, we give the conditions for the surfaces generate...
متن کاملAssessment of medical expenditures for sepsis:differentiating between cases with and without ruled-out diagnoses.
Setting public health priorities requires precise estimation of the burden of disease, including disease-specific medical expenditure. Information on multiple and ruled-out diagnoses on health insurance claims (HICs) has been ignored in traditional analyses of disease-specific medical expenditures in Japan. This study reviewed 448 inpatients with at least one diagnosis of sepsis on their HICs, ...
متن کاملThe Coleman - Weinberg Phase Transition in Extended Higgs Models Marc
In Coleman-Weinberg symmetry breaking, all dimensionful parameters vanish and the symmetry is broken by loop corrections. Before Coleman-Weinberg symmetry breaking in the Standard Model was experimentally ruled out, it had already been excluded on cosmological grounds. In this Brief Report, the cosmological analysis is carried out for Coleman-Weinberg models with extended Higgs sectors, which a...

متن کاملGiant Thymolipoma Mimicking Cardiomegaly
A 28-year-old man presented with a chest radiograph strongly suggestive for cardiomegaly. Although he did not consent any hemodynamic studies, cardiomegaly was ruled out on the basis of the clinical course. Computed tomography showed the existence of a large mass in both sides of the heart and in both lower hemithoraces. The tumor was resected by anterior mediastinotomy; it was weighted 2100 g ...
متن کاملPrimordial perturbations from inflation
I review the standard analysis of adiabatic scalar and tensor perturbations produced by slow-roll inflation driven by a single scalar field, before going on to discuss recent work on the role of non-adiabatic modes during and after inflation. Isocurvature perturbations correlated with adiabatic modes may be produced during multi-field inflation and would give valuable information about the phys...
