    • Identification techniques for highly boosted W bosons that decay into hadrons 

      Baarmand, Marc M.; Hohlmann, Marcus; Kalakhety, H.; Yumiceva, Francisco X.; The CMS Collaboration; Khachatryan, Vardan; Sirunyan, A. M.; Tumasyan, A. R.; Adam, Wolfgang; Bergauer, Thomas (2014-12-02)
      In searches for new physics in the energy regime of the LHC, it is becoming increasingly important to distinguish single-jet objects that originate from the merging of the decay products of W bosons produced with high ...
    • Measurement of prompt J/ψ pair production in pp collisions at√s = 7 Tev 

      Baarmand, Marc M.; Hohlmann, Marcus; Kalakhety, H.; Yumiceva, Francisco X.; The CMS Collaboration; Khachatryan, Vardan; Sirunyan, A. M.; Tumasyan, A. R.; Adam, Wolfgang; Bergauer, Thomas (2014-09)
      Production of prompt J/ψ meson pairs in proton-proton collisions at s√ = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb−1. The two J/ψ mesons ...
    • Measurement of the t t ¯ production cross section using events with one lepton and at least one jet in pp collisions at √s=13 TeV 

      The CMS Collaboration; Sirunyan, A.M.; Tumasyan, A.R.; Baarmand, M.M.; Bhopatkar, Vallary; Colafranceschi, Stefano; Hohlmann, Marcus; Noonan, D; Roy, Tuhin S.; Yumiceva, Francisco X. (2017-09-13)
      A measurement of the t t ¯ production cross section at s=13 TeV is presented using proton-proton collisions, corresponding to an integrated luminosity of 2.2 fb−1, collected with the CMS detector at the LHC. Final states ...

      Khachatryan, Vardan; The CMS Collaboration; Sirunyan, A. M.; Tumasyan, A. R.; Adam, Wolfgang; Bergauer, Thomas; Baarmand, Marc M.; Hohlmann, Marcus; Kalakhety, H.; Yumiceva, Francisco X. (2014-09)
      A search for the standard model Higgs boson produced in association with a top-quark pair (ttH) is presented, using data samples corresponding to integrated luminosities of up to 5.1 fb−1 and 19.7 fb−1 collected in pp ...
    • Search for top quark partners with charge 5/3 in proton-proton collisions at √s=13 TeV( 

      The CMS Collaboration; Sirunyan, A.M.; Tumasyan, A.R.; Baarmand, M.M.; Bhopatkar, Vallary; Colafranceschi, Stefano; Hohlmann, Marcus; Noonan, D.; Roy, Tuhin S.; Yumiceva, Francisco X. (2017-08-18)
      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 ...
