CMS is a general purpose experiment, designed to study the physics of pp collisions at 14 TeV at the Large Hadron Collider (LHC). It currently involves more than 2000 physicists from more than 150 institutes and 37 countries. The LHC will provide extraordinary opportunities for particle physics based on its unprecedented collision energy and luminosity when it begins operation in 2007.The principal aim of this report is to present the strategy of CMS to explore the rich physics programme offered by the LHC. This volume demonstrates the physics capability of the CMS experiment. The prime goals of CMS are to explore physics at the TeV scale and to study the mechanism of electroweak symmetry breaking-through the discovery of the Higgs particle or otherwise. To carry out this task, CMS must be prepared to search for new particles, such as the Higgs boson or supersymmetric partners of the Standard Model particles, from the start-up of the LHC since new physics at the TeV scale may manifest itself with modest data samples of the order of a few fb −1 or less. The analysis tools that have been developed are applied to study in great detail and with all the methodology of performing an analysis on CMS data specific benchmark processes upon which to gauge the performance of CMS. These processes cover several Higgs boson decay channels, the production and decay of new particles such as Z and supersymmetric particles, B s production and processes in heavy ion collisions. The simulation of these benchmark processes includes subtle effects such as possible detector miscalibration and misalignment. Besides these benchmark processes, the physics reach of CMS is studied for a large number of signatures arising in the Standard Model and also in theories beyond the Standard Model for integrated luminosities ranging from 1 fb −1 to 30 fb −1 . The Standard Model processes include QCD, B-physics, diffraction, detailed studies of the top quark properties, and electroweak physics topics such as the W and Z 0 boson properties. The production and decay of the Higgs particle is studied for many observable decays, and the precision with which the Higgs boson properties can be derived is determined. About ten different supersymmetry benchmark points are analysed using full simulation. The CMS discovery reach is evaluated in the SUSY parameter space covering a large variety of decay signatures.

“…As has been previously observed by LEP experiments [11], the hadronization of a b quark yields jets which have structures similar to gluon-initiated jets, from an experimental point of view. The LEP measurement studied jets produced in the decay of an on-shell Z boson, therefore was practically limited to the energy range E 50 GeV.…”

“…The Monte Carlo generators are tuned to match events taken with the OPAL experiment at a centre-of-mass energy of 91 GeV [27,28]. Using these same parameters, except of setting the appropriate centre-of-mass energy, a good description of the JADE data, down to smallest energies, is achieved [29].…”

We present a measurement of the strong coupling α S using the three-jet rate measured with the Durham algorithm in e + e − -annihilation using data of the JADE experiment at centre-of-mass energies between 14 and 44 GeV. Recent theoretical improvements provide predictions of the three-jet rate in e + e − -annihilation at nextto-next-to-leading order. In this paper a measurement of the three-jet rate is used to determine the strong coupling α S from a comparison to next-to-next-to-leading order predictions matched with next-to-leading logarithmic approximations and yields a value for the strong coupling α S (M Z 0 ) = 0.1199 ± 0.0010(stat.) ± 0.0021(exp.) ± 0.0054(had.) ± 0.0007(theo.), consistent with the world average. This paper is dedicated to the memory of Joachim Heintze, a founding member of the JADE collaboration whose essential contributions to JADE and the field are imperishable.
