The SM is, up to now, a robust model that describes with high accuracy the interactions between elementary particles. However, several processes, like the observation of neutrino oscillations or the presence of dark ...

The inorganic scintillator detectors are widely used in nuclear experiments. New advances on the development of such detectors make it necessary a continuous review of new materials and photosensors. In this work, four ...

This thesis work focuses on the measurement of the fission fragment angular distribution (FFAD) and fission cross section of the reactions 234U(n,f) y 235U(n,f) using PPAC (Parallel Plate Avalanche Counter) detectors at ...

In this thesis, measurements of the inelastic cross-sections of proton-proton collisions at centre-of-mass energies of \sqrt{s} = 5 TeV and \sqrt{s} = 13 TeV with the LHCb detector are presented. The cross-section ...

This thesis covers most of my research from 2007 to 2013 as a member of the High Energy Physics group in the Particle Physics department at the University of Santiago de Compostela. Most of this work was performed on ...

This research project will be carried out doing data analysis in the LHCb collaboration. LHCb is one of the four big experiments running in the Large Hadron Collider at CERN, and is mainly designed to make precise measurements ...

The LHCb experiment foresees a new era of high luminosity, aiming to clarify persistent tensions between experiments and the SM predictions, such as those related to the flavour sector. This thesis is devoted to the ...

Nesta tese estúdiase a sensibilidade do detector NEXT-100 á desintegración dobre beta sen neutrinos. Existe un gran interese na busca desta desintegración xa que podería respostar preguntas fundamentais en física de ...
