The results of a search for a supersymmetric partner of the top quark (top squark), pair-produced in proton-proton collisions at √{ s} = 8 TeV, are presented. The search, which focuses on R-parity violating, chargino-mediated decays of the top squark, is performed in final states with low missing transverse momentum, two oppositely charged

A search is presented for single top quark production in the s channel in proton-proton collisions with the CMS detector at the CERN LHC in decay modes of the top quark containing a muon or an electron in the final state. The signal is extracted through a maximum-likelihood fit to the distribution of a multivariate discriminant defined using

A search is presented for a heavy vector-like quark, decaying into a b quark and a W boson, which is produced singly in association with a light flavor quark and a b quark. The analysis is performed using a data sample of proton-proton collisions at a center-of-mass energy of √{ s} = 13TeV collected at the LHC in 2015. The data set used in the

A search for events containing four top quarks (t t bar t t bar) is reported from proton-proton collisions recorded by the CMS experiment at √{ s} = 13 TeV and corresponding to an integrated luminosity of 2.6 fb-1. The analysis considers the single-lepton (e or μ)+jets and the opposite-sign dilepton (μ+μ-, μ±e∓, or e+e-)+jets channels. It uses

A search is presented for the production of two Higgs bosons in final states containing two photons and two bottom quarks. Both resonant and nonresonant hypotheses are investigated. The analyzed data correspond to an integrated luminosity of 19.7 fb-1 of proton-proton collisions at √{s }=8 TeV collected with the CMS detector. Good agreement is

Based on MAGIC observations from 2007 June to July, we have obtained an integral upper limit to the VHE energy emission of the globular cluster M13 of F(E>200 GeV) 5.1 × 10-12 cm-2 s-1, and differential upper limits for E > 140 GeV. Those limits allow us to constrain the population of millisecond pulsars within M13 and to test models for
