Measurement of the azimuthal ordering of charged hadrons with the ATLAS detector
2012
This paper presents a study of the possible ordering of charged hadrons in the azimuthal angle relative to the beam axis in high-energy proton-proton collisions at the Large Hadron Collider (LHC). A spectral analysis of correlations between longitudinal and transverse components of the momentum of the charged hadrons, driven by the search for phenomena related to the structure of the QCD field, is performed. Data were recorded with the ATLAS detector at center-of-mass energies of √s=900 GeV and √s=7 TeV. The correlations measured in a kinematic region dominated by low-pT particles are not well described by conventional models of hadron production. The measured spectra show features consis…

Aplicacions de mètodes no pertorbatius a la dinàmica del sabor
2008
RESUMEN A día de hoy, el Modelo Estándar de las interacciones electrodébiles describe correctamente todos los fenómenos observados en la naturaleza. Sin embargo no proporciona ninguna explicación al hecho de que existan tres familias fermiónicas, incluyendo cada una quarks y leptones. Estas familias se distinguen por el grado de libertad sabor. Debido a la ruptura espontánea de la simetría local gauge, existe un patrón de sabor muy rico. En particular, las partículas tienen masas diferentes, y las diversas familias se mezclan (en el caso de los quarks) cuando interaccionan con los bosones mediadores. El conocimiento preciso de las masas y ángulos de mezcla de los quarks es fundamental para …
Collider aspects of flavour physics at high Q
2008
This chapter of the 'Flavor in the era of LHC' workshop report discusses flavor-related issues in the production and decays of heavy states at the LHC at high momentum transfer Q, both from the experimental and the theoretical perspective. We review top quark physics, and discuss the flavor aspects of several extensions of the standard model, such as supersymmetry, little Higgs models or models with extra dimensions. This includes discovery aspects, as well as the measurement of several properties of these heavy states. We also present publicly available computational tools related to this topic. © Springer-Verlag / Società Italiana di Fisica 2008.

Probing neutrino oscillations in supersymmetric models at the Large Hadron Collider
2010
The lightest supersymmetric particle may decay with branching ratios that correlate with neutrino oscillation parameters. In this case the CERN Large Hadron Collider (LHC) has the potential to probe the atmospheric neutrino mixing angle with sensitivity competitive to its low-energy determination by underground experiments. Under realistic detection assumptions, we identify the necessary conditions for the experiments at CERN's LHC to probe the simplest scenario for neutrino masses induced by minimal supergravity with bilinear R parity violation.
