This thesis is devoted to the study of the B0 → ρ(770)0K∗(892)0 decay mode for which 3 fb−1 of proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV were analysed. The ...

The dosimetry of the small and intensity modulated elds employed in radiotherapy, with high dose gradients involved, is a quite demanding task. The need for reliable measurements in these beams responds not only to ...

Research in heavy-ion collisions at very high colliding energies has dramatically changed the big picture of the theory of strong interactions under extreme conditions of temperature and density, the so-called hot and ...

This thesis is focused on the search of Ultra High Energy (UHE) neutrinos with energies above 10^17 eV with the Pierre Auger Observatory. The thesis has several parts. On the one hand in Chapter 2, the procedure used to ...

Firstly, NP implications in kaon physics are presented, both experimentally, at LHCb, and phenomenologically, under a supersymmetric framework. Secondly, a review on the measurement of the CP violating phase for B-mesons ...

Over the last decades, heavy ions collisions experiments at CERN and BNL have offered an unique window to study QCD under hot and dense conditions. In such high energy events a new state of matter, the quark gluon plasma, ...

The Standard Model (SM) of Particle Physics is a very successful theory, but it leaves some important questions unanswered. One long-standing mystery is the so called flavour structure, consisting on the specific arrangement ...

Quantum ChromoDynamics, the theory that describes the strong interaction in terms of quarks and gluons, allows several kinds of matter besides the usual hadrons. One such kind is the deconfined state known as quark-gluon ...
