Results are presented from a search for supersymmetric particles in scenarios with small mass splittings. The data sample corresponds to 19.7 fb-1 of proton-proton collisions recorded by the CMS experiment at √{ s} = 8 TeV. The search targets top squark (t ˜) pair production in scenarios with mass differences Δm = m (t ˜) - m (χ˜10) below the W

A search for supersymmetry is presented based on multijet events with large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of √{s }=13 TeV . The data, corresponding to an integrated luminosity of 35.9 fb-1 , were collected with the CMS detector at the CERN LHC in 2016. The analysis utilizes four

Results are reported from a search for supersymmetric particles in proton-proton collisions in the final state with a single, high transverse momentum lepton; multiple jets, including at least one b-tagged jet; and large missing transverse momentum. The data sample corresponds to an integrated luminosity of 2.3 fb-1 at √{s}=13 TeV, recorded by the

So far, surface magnetic fields have never been reported on Mira stars, while observational facilities allowing detection and measurement of weak surface fields through the Zeeman effect have become available. Then, in order to complete the knowledge of the magnetic field and of its influence during the transition from Asymptotic Giant Branch (AGB)

A search for the production of heavy partners of the top quark with charge 5/3 (X5/3) decaying into a top quark and a W boson is performed with a data sample corresponding to an integrated luminosity of 2.3 fb-1, collected in proton-proton collisions at a center-of-mass energy of 13 TeV with the CMS detector at the CERN LHC. Final states with

Searches are presented for heavy gauge bosons decaying into a top and a bottom quark in data collected by the CMS experiment at √{s}=13 TeV that correspond to an integrated luminosity of 2.2 and 2.6 fb-1 in the leptonic and hadronic analyses, respectively. Two final states are analyzed, one containing a single electron, or muon, and missing
