Observation of $Z$ production in proton-lead collisions at LHCb

2014

The first observation of $Z$ boson production in proton-lead collisions at a centre-of-mass energy per proton-nucleon pair of $\sqrt{s_{NN}}=5~\text{TeV}$ is presented. The data sample corresponds to an integrated luminosity of $1.6~\text{nb}^{-1}$ collected with the LHCb detector. The $Z$ candidates are reconstructed from pairs of oppositely charged muons with pseudorapidities between 2.0 and 4.5 and transverse momenta above $20~\text{GeV}/c$. The invariant dimuon mass is restricted to the range $60-120~\text{GeV}/c^2$. The $Z$ production cross-section is measured to be \begin{eqnarray*} ��_{Z\to��^+��^-}(\text{fwd})&=&13.5^{+5.4}_{-4.0}\text{(stat.)}\pm1.2\text{(syst.)}~\text{nb} …

Search for the neutral Higgs bosons of the Minimal Supersymmetric Standard Model in $pp$ collisions at $\sqrt{s}=7$ TeV with the ATLAS detector

2013

A search for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is based on a sample of proton-proton collisions at a centre-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron Collider. The data were recorded in 2011 and correspond to an integrated luminosity of 4.7 fb[superscript −1] to 4.8 fb[superscript −1]. Higgs boson decays into oppositely-charged muon or τ lepton pairs are considered for final states requiring either the presence or absence of b-jets. No statistically significant excess over the expected background is observed and exclusion limits at the 95% confidence level are derived. The exclusion limits ar…

2018

La búsqueda del bosón de Higgs fue la pieza central de los programas de física para los experimentos en el Gran Colisionador de Hadrones durante el Run 1 de la toma de datos. El descubrimiento de esta partícula, anunciado el 4 de julio de 2012 por las colaboraciones de ATLAS y CMS, representó un hito a la hora de comprender el mecanismo de ruptura de simetría electrodébil, por el cual las partículas fundamentales adquieren masa. Ahora es esencial que el bosón de Higgs sea ampliamente estudiado. Las mediciones precisas de sus propiedades confirmarán su naturaleza y cualquier desviación de la predicción del Modelo Estándar representará un signo claro de nueva física. Esta tesis presenta dos a…

Precise Phenomenology in the LHC era

2021

Desde la detección del bosón de Higgs en 2012, la comunidad experimental ha centrado sus esfuerzos en la medida de precisión del Modelo Estándar (SM, por sus siglas en inglés). Para satisfacer las demandas de la precisión experimental al LHC en el futuro cercano, cálculos a segundo orden en teoría de perturbaciones son necesarios. El LHC es un colisionador hadrónico, lo que significa que una alta multiplicidad en el estado final es de esperarse debido a la radiación QCD. Para comparar nuestras predicciones teóricas con el experimento, esta radiación QCD debe ser modelada y calculada, lo que se hace utilizando cascádas partónicas mediante generadores de evento de Monte Carlo (MC). Los MCs, n…
