Measurements are presented of the lifetimes of the {B^0}, B^0_{s}, Λ_{b} ^0, and B_{c}^+ hadrons using the decay channels {B^0} → J/ψ K^{*}(892)0, B^0 → J/ψ K^0_S, B^0_{s} → J/ψ {π ^+}{π ^-}, B^0_{s} → J/ψ {φ (1020)}, Λ_{b}^0 → J/ψ Λ0, and B_{c}^+ → J/ψ {π ^+}. The data sample, corresponding to an integrated luminosity of 19.7 {fb}^ {-1}, was

Angular distributions of the decay B0 →K*0μ+μ- are studied using a sample of proton-proton collisions at √{ s } = 8TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 20.5fb-1. An angular analysis is performed to determine the P1 and P5‧ parameters, where the P5‧ parameter is of particular interest because

We introduce VLT-MUSE observations of the central 2'× 2' (30 × 30 pc) of the Tarantula Nebula in the Large Magellanic Cloud. The observations provide an unprecedented spectroscopic census of the massive stars and ionised gas in the vicinity of R136, the young, dense star cluster located in NGC 2070, at the heart of the richest star-forming region

A critical issue in the asymptotic giant branch (AGB) self-enrichment scenario for the formation of multiple populations in globular clusters (GCs) is the inability to reproduce the magnesium isotopic ratios, despite the model in principle can account for the depletion of magnesium. In this work, we analyse how the uncertainties on the various p

Using a representative sample of 14 star-forming dwarf galaxies in the local Universe, we show the existence of a spaxel-to-spaxel anticorrelation between the index N2 ≡ log ([N II]λ 6583/H α ) and the H α flux. These two quantities are commonly employed as proxies for gas-phase metallicity and star formation rate (SFR), respectively. Thus, the

Thousands of RR Lyrae stars have been observed by the Kepler space telescope so far. We developed a photometric pipeline tailored to the light variations of these stars, called the Extended Aperture Photometry (EAP). We present the comparison of our photometric solutions for Campaigns 0 through 6 with the other pipelines available, e.g., SAP/PDCSAP
