Study of KS KL Coupled Decays and KL -Be Interactions with the CMD-2 Detector at VEPP-2M Collider

The integrated luminosity about 4000 inverse nanobarn of around phi meson mass ( 5 millions of phi mesons) has been collected with the CMD-2 detector at the VEPP-2M collider. A latest analysis of the KS KL coupled decays based on 30 % of available data is presented in this paper. The KS KL pairs from phi meson decays were reconstructed in the drift chamber when both kaons decayed into two charged particles. From a sample of 1423 coupled decays a selection of candidates to the CP violating KL into pi+ pi- decay was performed. CP violating decays were not identified because of the domination of events with a KL regenerating at the Be beam pipe into KS and a background from KL semileptonic decays. The regeneration cross section of 110 MeV/c KL mesons was found to be 53 +- 17 mb in agreement with theoretical expectations. The angular distribution of KS mesons after regeneration and the total cross section of KL for Be have been measured.Comment: 14 pages, 8 figure

Spectral characteristics of anisotropic dielectric disk resonator with imperfect conducting end walls

The electrodynamic analysis of a dielectric disk resonator with imperfect conducting end walls is carried out at excitation of "whispering gallery" oscillations. The possibility of solving the inverse problem is considered: it consists in the determination of permittivity tensor components of anisotropic uniaxial crystal. The spectral characteristics of teflon disk resonator with copper end surfaces are studied in the 8 mm wave band

Выбор оперативного доступа при эхинококкозе печени у детей (RUS)

The use of laparoscopic devices in hydatidectomy is caused by the severity of the operative trauma and prolonged duration of rehabilitation in traditional operations. In the clinic of pediatric surgery of the Saratov state medical university 49 hydatidectomies in cases of hydatid cysts of the liver using the traditional laparotomic and laparoscopic approaches in patients aged 4-15 were performed
