For more than half a century, colliders have been in the forefront of studying the Standard Model (SM) predictions. The pinnacle of both SM and colliders occurred when on July the 4th 2012, at CERN Large ...

In this thesis we present several studies on the origin of masses at the LHC. First we study the indirect effects of new physics on the couplings of the recently discovered Higgs boson and on the ...

Radiative decays of B mesons, a good example of Flavor Changing Neutral Currents, are interesting for the study of physics beyond the Standard Model, as new high-energy phenomena can enter in the loop. ...

The LHCb detector features an outstanding capability to identify displaced secondary vertices with respect to the interaction point. The extraordinary performance of the whole LHCb tracking system makes ...
Picatoste Olloqui, Eduardo (Date of defense: 2016-12-22)
LHCb is one of the four large experiments of the Large Hadron Collider (LHC) based at CERN. The LHCb experiment is taking data at its nominal design luminosity. However, in order to distinguish among ...

Flavour Tagging at the LHCb experiment is a fundamental tool for the measurement of B oscillations and the study of CP violation. This document explains the development of different tagging techniques ...

-Fischler-Srednicki-Zhitnisky axion model in light of the recent Higgs LHC results and electroweak precision data. This model is an extension of the two-Higgs-doublet model incorporating a PQ symmetry ...
Planells Noguera, Xumeu (Date of defense: 2014-11-06)
In this thesis we study the possibility that QCD breaks parity at high temperatures and densities, a scenario that may be tested in heavy ion collisions. We present two different approaches to this ...
Jiménez Tejero, Clara Estela (Date of defense: 2012-03-05)
In this thesis we have studied baryon resonances generated from the dynamical interaction of two hadrons. We are interested on this study as an alternative approach to explain the increasing number of ...
