2021
Interpolated production cross sections and cross-section ratio for $\Upsilon(1\mathrm{S}) \rightarrow \mu^{+}\mu^{-}$ and $\Upsilon(2\mathrm{S}) \rightarrow \mu^{+}\mu^{-}$ in proton–proton collisions, integrated over the rapidity interval 2.5–4.0 and $p_{\mathrm{T}} <$ 15 GeV/$c$. Results used for the determination of the integrated nuclear modification factors and of the nuclear modification factors as a function of centrality (Figures 4 and 5 (right)).

L'Unione Europea in materia di immigrazione asilo e refugio. Una strategia di accoglienza per rispondere alla esigenze dettate dai conflitti del XXI …
2018
La razón por la cual decidí comenzar este proyecto de investigación titulado "La Unión Europea sobre inmigración e integración; la reacción de la Unión ante la crisis de los refugiados y sus implicaciones para la gestión de la inmigración; una estrategia de acogida para responder a las exigencias planteadas por los conflictos del siglo XXI” es que creo que las políticas adoptadas por los gobiernos europeos en materia de asilo y refugio, sean la causa de la mala gestión de los flujos migratorios y de la falta de protección de los refugiados y de los solicitantes de asilo que en los últimos años han llamado insistentemente a las puertas de la Unión Europea en busca de refugio. En los últimos …
Search for a Stable Six-Quark State at BABAR
2019
Recent investigations have suggested that the six-quark combination uuddss could be a deeply bound state (S) that has eluded detection so far, and a potential dark matter candidate. We report the first search for a stable, doubly strange six-quark state in Upsilon -> S anti-Lambda anti-Lambda decays based on a sample of 90 million Upsilon(2S) and 110 million Upsilon(3S) decays collected by the BABAR experiment. No signal is observed, and 90% confidence level limits on the combined Upsilon(2S,3S) -> S anti-Lambda anti-Lambda branching fraction in the range (1.2-1.4)x10^-7 are derived for m_S < 2.05 GeV. These bounds set stringent limits on the existence of such exotic particles.
