Figure 1. γγ collision in ee scattering These two photons then can interact to form a state X with mass Wγγ . The fourmomentum transfer qi to the photons depends on the angle and energy of the scattered electrons. When neither of the scattered electrons is detected (untagged events), the virtual photons are referred to as nearly real i.e. q 1 ≈ q 2 ≈ 0. This class of events allows several tests...
The exclusive production of charged pions, are reported in the proton-proton collisions, where the π+π- pair is emitted at the central rapidity, y, and the scattered protons stay intact (p) without detection. This measurement is performed with the CMS detector at the LHC, using a data sample corresponding to an integrated luminosity of 450 μb-1 collected at a center-of-mass energy of 7 TeV. Th...
An optical method has been proposed and its system has been developed for measuring the change in diameter during the production of polyester filament in a manufacturing plant. The principle of the method is based on the application of scattered light on the filament. The sensor head of the system consisted of a semiconductor laser, two silicon-photodiodes as a light receiver, and a cylindrical...
Animal production has moved quite rapidly to a consolidated structure of fewer, larger farms, ranches, and animal feeding units in both developed and developing countries. Driven by economies of scale arising from steady advances in technology, the trend shows no sign of slowing. This new structural concept and features increased concentration of large-scale livestock and specialty crop product...
Although clustering of genes from the same metabolic pathway is a widespread phenomenon, the evolution of the polysaccharide biosynthetic gene cluster remains poorly understood. To determine the evolution of this pathway, we identified a scattered production pathway of the polysaccharide sanxan by Sphingomonas sanxanigenens NX02, and compared the distribution of genes between sphingan-producing...
the purpose of the present study was to investigate the effect of task-based instruction of vocabulary on the receptive and oral productive acquisition of english vocabulary and compare the results with those obtained from the traditional method. the method and procedure applied in this study was as follows: after the implementation of opt, a group of sixty female students were chosen. the stu...
in this paper, a numerical procedure for an inverse problem of simultaneously determining an unknown coefficient in a semilinear parabolic equation subject to the specification of the solution at an internal point along with the usual initial boundary conditions is considered. the method consists of expanding the required approximate solution as the elements of the inverse quadrati...
