Multiparticle Correlations at LEP1

Bidding farewell to the LEP accelerator, we acknowledge that an essential part of its legacy is the immense amount of data collected during 5 years of the LEP1 stage, at the Z peak. This set of data allows for detailed studies of many phenomena, and particularly, of the final state interactions between hadrons. Presented here is a review of the most recent analyses in this area.Comment: 6 pp, 4 figs, talk presented at the XXX International Symposium on Multiparticle Dynamics, October 9-15, 2000, Tihany, Hungar

Studies of the fragmentation process in hadronic decays of Z⁰ boson

This thesis is based on the work that was done during 1992--1996 at the DELPHI detector at LEP. Its main parts are outlined below. The brief Introduction gives an overview of the science of Particle Physics, its development and contemporary status. The first chapter represents an introduction to the DELPHI detector at LEP, describing the main features of the LEP machine and the DELPHI detector as means to obtain an important information for the analysis. The second chapter is devoted to description of the development of one of the components of the DELPHI detector: the hadron calorimeter and its cathode readout system in particular. The third chapter describes the wide possibilities of QCD analysis using the information about hadronic decays of the Z boson produced in e+e- annihilation. The main goal of this work was to extract different components of the charged hadron cross section and to derive the gluon fragmentation function. In the fourth chapter results of the studies of two-particles correlations in hadronic Z decays are presented. The analysis of directional and transverse mass dependences of the Bose-Einstein correlations is performed

High Transverse Momentum Physics at the Large Hadron Collider

This note summarizes many detailed physics studies done by the ATLAS and CMS Collaborations for the LHC, concentrating on processes involving the production of high mass states. These studies show that the LHC should be able to elucidate the mechanism of electroweak symmetry breaking and to study a variety of other topics related to physics at the TeV scale. In particular, a Higgs boson with couplings given by the Standard Model is observable in several channels over the full range of allowed masses. Its mass and some of its couplings will be determined. If supersymmetry is relevant to electroweak interactions, it will be discovered and the properties of many supersymmetric particles elucidated. Other new physics, such as the existence of massive gauge bosons and extra dimensions can be searched for extending existing limits by an order of magnitude or more.Comment: Authors listed are the editor

Automated calculation of the absorber temperature field of an inflatable collector

This article deals with calculating temperature field of the inflatable collector made of polymer materials. The efficiency of the considered power system depends on the intensity of the absorber heating. In its turn, the process of heating coolant is affected by a great number of external environmental factors. The developed mathematical model and program product let the researchers consider various influence degree of each factor separately and in a complex
