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.
This report presents the capabilities of the CMS experiment to explore the rich heavy-ion physics programme offered by the CERN Large Hadron Collider (LHC). The collisions of lead nuclei at energies √ s N N = 5.5 TeV, will probe quark and gluon matter at unprecedented values of energy density. The prime goal of this research is to study the fundamental theory of the strong interaction -Quantum Chromodynamics (QCD) -in extreme conditions of temperature, density and parton momentum fraction (low-x).This report covers in detail the potential of CMS to carry out a series of representative Pb-Pb measurements. These include "bulk" observables, (charged hadron multiplicity, low p T inclusive hadron identified spectra and elliptic flow) which provide information on the collective properties of the system, as well as perturbative probes such as quarkonia, heavy-quarks, jets and high p T hadrons which yield "tomographic" information of the hottest and densest phases of the reaction.
MMP16 stands for 16-bit Didactic Micro-Programmed Micro-Processor and consists in a comprehensive learning tool for those students of electric engineering and related disciplines that, having studied the basics of digital electronics, need to understand the principles of computer organization prior to study advanced computer architecture. Therefore, MMP16 has been designed as a bridge between the study and use of digital electronic components and a full implementation of a digital microprocessor. MMP16 is a powerful tool not only to depict the basic concepts of a microprocessor layout and operation, but also to instruct advanced concepts such as pipelining. Besides the theoretical approach, MMP16 may be used as a software developing tool, allowing the students to develop and test their own microprograms using the simulation software provided. MMP16 is currently being used in the Universidad Politécnica de Madrid (UPM) and its deployment is under study in several European and Chinese universities.
Purpose – The purpose of the paper is to analyse the current status of the Chinese research and development (R&D) system in a global environment, compared to those of other nations. Design/methodology/approach – Extracting meaningful information from organisation for economic co-operation and development (OECD) (research intensity), Thomson Reuters (research output), UNESCO and cross-border education research team (C-BERT) (mobility) databases and analysing de facto international standards such as university rankings, the Chinese system is compared to those of other scientific powers (the world top expenders in R&D such as the USA, Japan, Korea, Taiwan and some European nations), both using absolute production values and those relative to the productivity of the R&D workforce, so a general view of such a system is offered to complement previous analyses. Findings – A rather utilitarian approach to R&D policy, linked to economic growth, with a strong role of a Government-backed industry and based on applied R&D rather than on basic science, is found. The emergence of China as a scientific power relies heavily on a small number of institutions and efficiency becomes the priority, as confirmed by the growing presence of Chinese universities in university rankings – which is linked to some internationalisation efforts – and by the quantitative analysis of science and technology macro-indicators. Nevertheless, those results still remain modest when the overall size of the Chinese R&D system is considered. Originality/value – A general view of the Chinese system is offered in this study by combining both the analysis of the inputs of the Chinese R&D (in a internationally comparable way) system and outputs (up to international standards).
