Measurement of thett¯production cross section inpp¯collisions ats=1.96 TeVusing soft electronb-tagging
The authors present a measurement of the t{bar t} production cross section using events with one charged lepton and jets from p{bar p} collisions at a center-of-mass energy of 1.96 TeV. A b-tagging algorithm based on the probability of displaced tracks coming from the event interaction vertex is applied to identify b quarks from top decay. Using 318 pb{sup -1} of data collected with the CDF II detector, they measure the t{bar t} production cross section in events with at least one restrictive (tight) b-tagged jet and obtain 8.9{sub -1.0}{sup +1.0}(stat.){sub -1.0}{sup +1.1}(syst.) pb. The cross section value assumes a top quark mass of m{sub t} is presented in the paper. This result is cons…
Jobs Act e tutela contrattuale della persona: un'involuzione?
The need to adapt to the economic system promoted by the European Union generated a wave of reform in the field of labor law that invested Italy and France. This essay explores the impact of the Italian Jobs Act on the contractual protection of the worker. In particular: i) the weakening of the concept of the employment relationship as a tool for the realization of the worker understood as both a human being and a professional; and ii) the emphasis given to the protection against discriminations. The focus on the latter represents the link with the French reform and creates the premises for the author’s considerations and questions on the idea of the human being promoted by the European Uni…
