Search for physics beyond the standard model in events with two leptons, jets, and missing transverse momentum in pp collisions at √S= 8 TeV
Abstract: A search is presented for physics beyond the standard model in final states with two opposite-sign same-flavor leptons, jets, and missing transverse momentum. The data sample corresponds to an integrated luminosity ...
Identification techniques for highly boosted W bosons that decay into hadrons
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 the ratio B(t→Wb)/B(t→Wq) in pp collisions at √s=8 TeV
The ratio of the top-quark branching fractions R = B(t → Wb)/B(t → Wq), where the denominator includes the sum over all down-type quarks (q = b, s, d), is measured in the tt dilepton ¯ final state with proton–proton ...
Search for narrow high-mass resonances in proton-proton collisions at √s = 8 TeV decaying to a Z and a Higgs boson
A search for a narrow, high-mass resonance decaying into Z and Higgs (H) bosons is presented. The final state studied consists of a merged jet pair and a τ pair resulting from the decays of Z and H bosons, respectively. ...
Search for vector-like T quarks decaying to top quarks and Higgs bosons in the all-hadronic channel using jet substructure
A search is performed for a vector-like heavy T quark that is produced in pairs and that decays to a top quark and a Higgs boson. The data analysed correspond to an integrated luminosity of 19.7 fb−1 collected with the CMS ...
