Searching for flavored gauge bosons

Abstract Standard Model may allow an extended gauge sector with anomaly-free flavored gauge symmetries, such as Li −Lj , Bi −Lj , and B −3Li, where i, j = 1, 2, 3 are flavor indices. We investigate phenomenological implications of the new flavored gauge boson Z′ in the above three classes of gauge symmetries. Focusing on the gauge boson mass above 5 GeV, we use the lepton...

Scalar dark matter search from the extended νTHDM

Abstract We consider a neutrino Two Higgs Doublet Model (νTHDM) in which neutrinos obtain naturally small Dirac masses from the soft symmetry breaking of a global U(1) X symmetry. We extended the model so the soft term is generated by the spontaneous breaking of U(1) X by a new scalar field. The symmetry breaking pattern can also stabilize a scalar dark matter candidate. After...

Production of heavy neutrino in next-to-leading order QCD at the LHC and beyond

Majorana and pseudo-Dirac heavy neutrinos are introduced into the type-I and inverse seesaw models, respectively, in explaining the naturally small neutrino mass. TeV scale heavy neutrinos can also be accommodated to have a sizable mixing with the Standard Model light neutrinos, through which they can be produced and detected at the high energy colliders. In this paper we...

Testing the 2-TeV resonance with trileptons

The CMS collaboration has reported a 2.8σ excess in the search of the SU(2) R gauge bosons decaying through right-handed neutrinos into the two electron plus two jets (eejj) final states. This can be explained if the SU(2) R charged gauge bosons W R ± have a mass of around 2 TeV and a right-handed neutrino with a mass of \( \mathcal{O} \)(1) TeV mainly decays to electron. Indeed...
