Context. Tracing the molecular gas-phase in low-mass star-forming galaxies becomes extremely challenging due to significant UV photo-dissociation of CO molecules in their low-dust, low-metallicity ISM environments. Aims: We aim to study the molecular content and the star-formation efficiency of a representative sample of 21 blue compact dwarf

We present the first single-burst stellar population models, which covers the optical and the infrared wavelength range between 3500 and 50 000 Å and which are exclusively based on empirical stellar spectra. To obtain these joint models, we combined the extended MILES models in the optical with our new infrared models that are based on the IRTF

A first measurement of the top quark spin asymmetry, sensitive to the top quark polarisation, in t-channel single top quark production is presented. It is based on a sample of pp collisions at a centre-of-mass energy of 8 TeV corresponding to an integrated luminosity of 19.7 fb-1. A high-purity sample of t-channel single top quark events with an

A new set of measurements of the top quark mass are presented, based on the proton-proton data recorded by the CMS experiment at the LHC at √{s }=8 TeV corresponding to a luminosity of 19.7 fb-1 . The top quark mass is measured using the lepton+jets , all-jets and dilepton decay channels, giving values of 172.35 ±0.16 (stat )±0.48 (syst ) GeV , 172

Results on two-particle angular correlations for charged particles produced in p p collisions at a center-of-mass energy of 13 TeV are presented. The data were taken with the CMS detector at the LHC and correspond to an integrated luminosity of about 270 nb-1 . The correlations are studied over a broad range of pseudorapidity (|η | 2.0 ), near-side

Integrated fiducial cross sections for the production of four leptons via the H → 4 ℓ decays ( ℓ = e, μ) are measured in pp collisions at √{s}=7 and 8TeV. Measurements are performed with data corresponding to integrated luminosities of 5.1 fb-1 at 7TeV, and 19.7 fb-1 at 8 TeV, collected with the CMS experiment at the LHC. Differential cross
