This paper reports the measurement of J/{ψ } meson production in proton-proton (pp) and proton-lead (pPb) collisions at a center-of-mass energy per nucleon pair of 5.02 {TeV} by the CMS experiment at the LHC. The data samples used in the analysis correspond to integrated luminosities of 28 {pb}^{-1} and 35 {nb}^{-1} for pp and pPb collisions

Dwarf irregular galaxies (dIrrs) are the smallest stellar systems with extended H i discs. The study of the kinematics of such discs is a powerful tool to estimate the total matter distribution at these very small scales. In this work, we study the H i kinematics of 17 galaxies extracted from the 'Local Irregulars That Trace Luminosity Extremes

We report observations of dense molecular gas in the star-forming galaxy EGS 13004291 (z = 1.197) using the Plateau de Bure Interferometer. We tentatively detect HCN and HNC J=2\to 1 emission when stacked together at 4σ significance, yielding line luminosities of {L}{HCN(J=2\to 1)}\prime =(9+/- 3)× {10}9 K km s‑1 pc2 and {L}{HNC(J=2\to 1)}\prime =

The frequency of multiple systems and their properties are key constraints of stellar formation and evolution. Formation mechanisms of very low-mass (VLM) objects are still under considerable debate, and an accurate assessment of their multiplicity and orbital properties is essential for constraining current theoretical models. Taking advantage of

There is a thin transition region (TR) in the solar atmosphere where the temperature rises from 10,000 K in the chromosphere to millions of degrees in the corona. Little is known about the mechanisms that dominate this enigmatic region other than the magnetic field plays a key role. The magnetism of the TR can only be detected by polarimetric

The spectra of charged particles produced within the pseudorapidity window | η| 1 at √{s_{NN}}=5.02 TeV are measured using 404 μb-1 of PbPb and 27.4 pb-1 of pp data collected by the CMS detector at the LHC in 2015. The spectra are presented over the transverse momentum ranges spanning 0 .5 p T 400 GeV in pp and 0 .7 p T 400 GeV in PbPb
