The collimation C of a hadronic event in the e + e −-annihilation is defined as the average of cos θ, C =< cos θ >, where θ is the angle of each hadron measured from the thrust axis, and the average is over all the hadrons produced in an event. It is an infrared-stable event-shape parameter. 1−C, the difference between the unity and the average collimation at a given energy, is proportional to ...

There are several parametric models to describe the charged particle multiplicity distributions in literature. Among them, log-normal distribution and negative binomial most well-known models. In this study, compared tested neutrino interactions produced DONUT experiment. This analysis was carried out using real experimental results of Collaboration. The show that data, reported by collaboratio...

Cf sources are especially interesting for calibrating passive multiplicity counters without the need for Pu because: they are genuinely point-like and being lightly encapsulated offer a nearly isotropic unperturbed fission spectrum of neutrons for all practical purposes they can be considered as a pure source of spontaneous fission neutrons which considerably simplifies interpolation. That is t...

We review the main result of cond-mat/0503564. The Hamiltonian of the XXZ spin chain and the transfer matrix of the six-vertex model has the sl2 loop algebra symmetry if the q parameter is given by a root of unity, q 0 = 1, for an integer N . We discuss the dimensions of the degenerate eigenspace generated by a regular Bethe state in some sectors, rigorously as follows: We show that every regul...

in the modern era, under the  influence of the western literary criticism has been highly spoken  about organic  unity in arabic ode but many  researchers and critics is established incomplete concept of organic unity in their minds and think it means the ode become confined  to an personal experience or a feeling and while they study it in the poetry they are amaze between logical unity and th...

The mainstream rationale for equating "brain death" (BD) with death is that the brain confers integrative unity upon the body, transforming it from a mere collection of organs and tissues to an "organism as a whole." In support of this conclusion, the impressive list of the brain's myriad integrative functions is often cited. Upon closer examination, and after operational definition of terms, h...
