SuWt 2 is a planetary nebula consisting of a bright ring-like waist from which protrude faint extended lobes - a morphology believed to be typical of progenitors which have experienced a close-binary evolution. Previous observations of NSV 19992, the star at the projected centre of SuWt 2, have found it to comprise two A-type stars in a 4.9 d

We report the discovery of eight new giant planets, and updated orbits for four known planets, orbiting dwarf and subgiant stars using the CORALIE, HARPS, and MIKE instruments as part of the Calan-Hertfordshire Extrasolar Planet Search. The planets have masses in the range 1.1-5.4 MJ's, orbital periods from 40 to 2900 d, and eccentricities from 0.0

The CMS tracker consists of 206 m2 of silicon strip sensors assembled on carbon fibre composite structures and is designed for operation in the temperature range from -25 to +25°C. The mechanical stability of tracker components during physics operation was monitored with a few μm resolution using a dedicated laser alignment system as well as

Cross sections for the production of a Z boson in association with jets in proton-proton collisions at a centre-of-mass energy of √{s}=8 TeV are measured using a data sample collected by the CMS experiment at the LHC corresponding to 19.6 fb-1. Differential cross sections are presented as functions of up to three observables that describe the jet

The WZ production cross section is measured by the CMS experiment at the CERN LHC in proton-proton collision data samples corresponding to integrated luminosities of 4.9 {fb}^{-1} collected at √{s} = 7 {TeV} , and 19.6 {fb}^{-1} at √{s} = 8 {TeV} . The measurements are performed using the fully-leptonic WZ decay modes with electrons and muons in

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
