High energy scattering and emission in QED&QCD media
(2018)
A formalism for the evaluation of the intensity of photon and gluon
bremsstrahlung in QED and QCD condensed media is presented which
considers general interactions beyond the Fokker-Planck approximation,
the angular ...
Holographic duality and applications
(2016)
In this thesis we review some results on the generalization of the gauge/gravity duality to new
cases by using T-duality and by including fundamental matter, finding applications to condensed
matter physics. First, we ...
Characterisation and Optimisation of Radiation-Tolerant Silicon Sensors with Intrinsic Gain
(2018)
The aim of this thesis is to characterise LGADs and DD-APDs before and after irradiation, and study the performance degradation (loss of signal, loss of gain, inhomogeneous spatial response, etc.) as a function of radiation ...
Study of the B0→ρ(770)0K*(892)0 decay with an amplitude analysis of B0→(π+π−)(K+π−) decays
(2019)
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 ...
Phenomenological studies of initial state effects and jet quenching in High-Energy Nuclear Collisions at LHC
(2017)
Heavy ion collisions (HICs) are the appropriate tools to study the so-called quark-gluon plasma
(QGP). This thesis is focused on the analysis of two types of effects arising in HICs: initial state
effects and final state ...
Holographic thermalization in finite-size systems
(2017)
The AdS/CFT correspondence has provided a fascinating window into the real-time dynamics of strongly-coupled QFTs. On the other hand, studies of gravitational collapse in asymptotically global AdS spacetimes have unraveled ...
Bayesian analysis of the mass composition of Ultra-High Energy Cosmic Rays using Xmax data recorded at the Pierre Auger Observatory
(2017)
Understanding the composition of Ultra High Energy Cosmic Rays (UHECRs) at Earth is crucial to unveil their origin and propagation mechanisms, and it is thus one of the main current challenges in the field of Astroparticle ...
Jet quenching and heavy ion collisions
(2020)
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 ...
Ultra-high-energy neutrino search with the Pierre Auger Observatory in the era of Gravitational Wave astronomy
(2021)
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 ...
New physics implications and searches at LHCb
(2019)
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 ...
