A Precise Determination of the Number of Families With Light Neutrinos and of the Z Boson Partial Widths
Title : The socialization at work in the federal universe, the determining element of the social regulation of the sports organization. Contribution to the social politics of the sport service of Nice city Abstract : This study postulates the existence of certain specific cultural determinism in the social regulation of the sports organization. It leans on a work of inquiry which concerns 148 agents of the municipal service of the sports of the Nice city. The investigation puts in evidence a causal report between the type of trajectory of professional insertion of the municipal agents and their level of support in the manager politics of the organization. The agents, whose bibliographic rou…
Measurement of α from the structure of particle clusters produced in hadronic Z decays
Abstract Using 106 000 hadronic events obtained with the ALEPH detector at LEP at energies close to the Z resonance peak, the strong coupling constant αs is measured by an analysis of energy-energy correlations (EEC) and the global event shape variables thrust, C-parameter and oblateness. It is shown that the theoretical uncertainties can be significantly reduced if the final state particles are first combined in clusters using a minimum scaled invariant mass cut, Ycut, before these variables are computed. The combined result from all shape variables of pre-clustered events is αs(MZ2 = 0.117±0.005 for a renormalization scale μ= 1 2 M Z . For μ values between MZ and the b-quark mass, the res…
