  • QCD, soft physics, and heavy flavor measurements at the LHC
    Publication . Leonardo, N.
    Recent measurements in QCD, soft physics, and heavy flavor made with the CMS detector at the LHC are presented. A selection of first results at the new frontier collision energy of 13 TeV at LHC Run2 is shown. The collision environment is characterized by studying charged particle distributions and correlations. Inclusive jet, exclusive dimuon and b-hadron production cross-section measurements are reported.

  • Search for vectorlike light-flavor quark partners in proton-proton collisions at $\sqrt s$ =8  TeV
    Publication . CMS collaboration (2223 authors); Nayak, A.; Bargassa, P.; Beirão Da Cruz E Silva, C.; Calpas, B.; Di Francesco, A.; Faccioli, P.; Gallinaro, M.; Hollar, J.; Leonardo, N.; Lloret Iglesias, L.; Seixas, J.; Toldaiev, O.; Vadruccio, D.; Varela, J.; Vischia, P.; David, A.; Veckalns, V.; Musella, P.; Pela, J.; Delgado, A.
    A search is presented for heavy vectorlike quarks (VLQs) that couple only to light quarks in proton-proton collisions at s=8  TeV at the LHC. The data were collected by the CMS experiment during 2012 and correspond to an integrated luminosity of 19.7  fb−1. Both single and pair production of VLQs are considered. The single-production search is performed for down-type VLQs (electric charge of magnitude 1/3), while the pair-production search is sensitive to up-type (charge of magnitude 2/3) and down-type VLQs. Final states with at least one muon or one electron are considered. No significant excess over standard model expectations is observed, and lower limits on the mass of VLQs are derived. The lower limits range from 400 to 1800 GeV, depending on the single-production cross section and the VLQ branching fractions B to W, Z, and Higgs bosons. When considering pair production alone, VLQs with masses below 845 GeV are excluded for B(W)=1.0, and below 685 GeV for B(W)=0.5, B(Z)=B(H)=0.25. The results are more stringent than those previously obtained for single and pair production of VLQs coupled to light quarks.
