Accurate measurements of particles masses, couplings and widths are possible by measuring production cross sections near threshold. We discuss the prospects for performing such measurements at a high luminosity muon collider.

Results on the cross section measurement of Z boson pair–production at LEP 1,2 are presented. The more general case of neutral–current four–fermion production and the particular case of ZZ events enriched in b quarks are also discussed. All the results agree with the Standard Model predictions.

by determining normal ranges of spinal canal diameters we can make early diagnosis in persons who have lower diameters of spinal canal. these persons are predisposed to spinal canal stenosis that is a major cause of spinal radiculopathies. in different studies performed in several countries, minimum and maximum ranges of spinal canal diameters were different for each population. in this study, ...

The article describes the features of work beams with a thin transverse corrugated web plate. Exponential fractional regression is presented, which allows one to estimate relative height plate sections working together flanges, obtained by authors based on an analysis numerical experiments. Based work, method proposed for describing stress state arbitrary cross-section I-beam (the profile corru...

In this study an orthotropic slab finite element is developed to model orthotropic slabs in fire, using a layered 9-noded iso-parametric slab element and a 3-noded beam element. The element is assembled from a solid slab element which represents the continuous upper portion of the profile, and a special beam element which represents the ribbed lower portion. An equivalent width for the cross-se...

in this paper, economic convergence in selected oic (36 countries) is studied. the convergence hypothesis is tested through three approaches: beta convergence, sigma convergence, and time series model. ols is used for estimating the cross section model and cross variance is used to test the distributive model. for analyzing time series model, we used augmented dicky fuller test. beta convergenc...

in this study, farm level technical efficiency (te) and its determinants were investigated. a stochastic cobb-douglas (cd) production frontier was used to provide estimates of input-oriented te for a sample of 100 rain fed farms in two palestinian governorates. empirical findings showed that the estimated te of the farms in the pooled sample ranged from 35.7 to 95.6%, with a mean value of 72.2%...
