RESUMO
The Compact Linear Collider (CLIC) is an option for a future [Formula: see text] collider operating at centre-of-mass energies up to [Formula: see text], providing sensitivity to a wide range of new physics phenomena and precision physics measurements at the energy frontier. This paper is the first comprehensive presentation of the Higgs physics reach of CLIC operating at three energy stages: [Formula: see text], 1.4 and [Formula: see text]. The initial stage of operation allows the study of Higgs boson production in Higgsstrahlung ([Formula: see text]) and [Formula: see text]-fusion ([Formula: see text]), resulting in precise measurements of the production cross sections, the Higgs total decay width [Formula: see text], and model-independent determinations of the Higgs couplings. Operation at [Formula: see text] provides high-statistics samples of Higgs bosons produced through [Formula: see text]-fusion, enabling tight constraints on the Higgs boson couplings. Studies of the rarer processes [Formula: see text] and [Formula: see text] allow measurements of the top Yukawa coupling and the Higgs boson self-coupling. This paper presents detailed studies of the precision achievable with Higgs measurements at CLIC and describes the interpretation of these measurements in a global fit.
RESUMO
Research and evaluation of social representations as determinants of behaviour are fundamental components for health education and promotion programmes. The research presented in this article was funded as part of the "Europe against Cancer" programme, and follows the evolution over a five year period, of representations and behaviours of 1500 children from cities in France, Belgium, Spain, Greece, and Portugal. In each city, three different groups were followed and evaluated: Children in the first groups participated in a year-long tobacco prevention programme conducted by specially trained teachers; those in the second groups only participated in sporadic activities designed around World Tobacco Day; those in the third group did not participate in any particular tobacco prevention activities. The evaluation concentrated on analysing the changes in participants' social representations regarding tobacco and smoking related behaviour throughout the five year period. A variety of comparative analysis techniques were used to prepare, evaluate, and modify the content of the teacher training programmes in order to succeed in fulfilling one of the primary objectives of the programme--that of assisting teachers to develop educational attitudes for tobacco prevention in primary schools. The authors esteem that the type of training offered to the teachers had a marked influence on the length and type of programmes they offered to their students.
