Phenomenology of non-standard neutrino interactions
2016
Today neutrino physics is in a privileged position within the fascinating field of particle physics. From the discovery of neutrino oscillations by Super-Kamiokande in 1998, the door to physics beyond the Standard Model (SM in what follows) has been opened. This fact implies that neutrinos have to be massive in opposition to the Standard Model assumption. However, this is not a surprise completely, but it was already hinted from theoretical and experimental observations in the two decades prior to the discovery of the oscillatory phenomenon, as neutrino masses included in unification models or the observed deficit of the atmospheric and solar neutrino fluxes. As a consequence of this new pa…
Analisi degli infortuni nel settore della sanità in Sicilia attraverso i flussi informtivi INAIL REGIONI: limiti e scenari di miglioramento dei dati
2011
An analysis on the injury events occurred to the employees in Sicilian hospitals from 2006 to 2008 was carried out, thanks to data filed in the INAL database “Flussi Informativi INAIL ISPESL REGIONI”. A frequency distribution of accidents and an investigation of injury events modality of occurrence have been performed according to ESAW codification. Data limitation and critical aspects have been highlighted in order to propose development in data management process.
Phenomenology of low-scale Seesaw Models
2016
All the observed particles are well accommodated in the Standard Model, together with the basic forces. However, there are both experimental and theoretical hints that the Standard Model can not be a complete theory and that New Physics is needed. Some of the theoretical problems are: i) The flavor-puzzle, i.e., why are there three copies of particles differing only by their mass. Most of the free parameters in the Standard Model are linked to this puzzle. They have been measured, but their values do not follow any clear pattern and their origin remains elusive. ii) The strong CP problem, that is, why the CP symmetry is conserved in the strong interactions in the Standard Model, which is no…
