  2. 20. Separating Dijet Resonances using the Coloron Discriminant Variable at LHC

    parallel talk
    An exciting possibility for the upcoming 14 TeV run of the LHC is that a new strongly-coupled resonance decaying to dijets could be discovered. Once the resonance is detected, the immediate questions will be about the nature of the particle: is it colored? is it a vector, fermion, or scalar? This talk reviews the LHC discovery reach for a variety of dijet resonances and discusses a strategy...

  3. 84. Distinguishing dijet resonances at the LHC using jet energy profiles
    Natascia Vignaroli (Michigan State University)

    parallel talk
    Anticipating that a dijet resonance could be discovered at the 14 TeV LHC, we present a method to discern whether it is a quark-antiquark ($q\bar{q}$), quark-gluon ($qg$), or gluon-gluon ($gg$) resonance, which is based on the study of the energy profiles of the two leading jets in the dijet channel. Including statistical uncertainties in the signal and the QCD backgrounds, we show that one...

  4. 140. Color Discriminant Variable to Seperate Coloron and Leptophobic Z' at the LHC
    Pawin Ittisamai (Michigan State University)
    04/05/2015, 17:30
    parallel talk
    A vector resonance decaying to dijets could be discovered at the 14 TeV run of the LHC. Measurements available after the discovery of the resonance; namely, the dijet cross section, mass and width of the resonance, can determine its color structure via a method using the color discriminant variable. This talk illustrates that the measurements of the resonance's heavy flavor decays to top and...

  5. 207. Searches for new physics in high-mass di-fermion final states with the ATLAS detector at the LHC
    Jason Robert Veatch (University of Arizona (US))

    BSM
    parallel talk
    Many new physics scenarios beyond the Standard Model predict resonant or non-resonant production of a pair of high-transverse momentum fermions (light and heavy quarks, charged leptons and neutrinos). The high-mass resonant production of top-quark pairs or a top-quark and a bottom-quark is also a good benchmark process for boosted top-quark and high-pT b-quark tagging. This talk...

  6. 191. Search for ttbar resonances at CMS
    Irving Daniel Sandoval Gonzalez (University of Illinois at Chicago (US))

    BSM
    parallel talk
    A search is presented for resonant top quark pair production. The full dataset recorded with the CMS detector in proton-proton collisions at a centre-of-mass energy of 8 TeV is used. The search is performed by measuring the invariant mass distribution of the top-quark pair and testing for deviations from the Standard Model prediction. Final states with no, one or two leptons are considered and...

  7. 86. Heavy Colour-Octet Particles at the LHC
    Keith Lee
    04/05/2015, 18:15
    parallel talk
    The top quark may hold the key to new physics associated with the electroweak symmetry-breaking sector. Many models beyond the Standard Model, especially those with a colour-triplet top-quark partner, contain a heavy colour-octet state. The "naturalness" argument for a light Higgs boson suggests that the colour octet can be pair-produced with large cross sections at the Large Hadron Collider...
