Minimal cascade decay of the top quark through a new scalar
Bogdan A. Dobrescu, Max H. Fieg, Alessandro Russo
We explore a possible decay of the top quark into a new scalar plus a charm quark. The decay is mediated by a dimension-5 operator that may be generated by the exchange of a…
Octet scalars shaping LHC distributions in 4-jet final states
Bogdan A. Dobrescu, Max H. Fieg
We study properties of a hypothetical scalar particle, , which is a color octet and an electroweak singlet. At hadron colliders, is pair produced through its QCD coupling to…
Multi-top signals of vectorlike quarks at the LHC
Elias Bernreuther, Bogdan A. Dobrescu
We point out that events with 6 or more top quarks may be observed at the LHC if certain particles exist at the TeV scale. In a model where a vectorlike quark of charge 2/3 decays…
Quark-universal breaking scalar at the LHC
Lorin Armbruster, Bogdan A. Dobrescu, Felix Yu
If the quarks or leptons are charged under a new gauge symmetry, then besides a boson there must exist at least one new boson whose decay products include Standard Mode…
Ultraheavy diquark decaying into vectorlike quarks at the LHC
Ioana Duminica, Calin Alexa, Ioan M. Dinu +2
We explore the discovery potential of an ultraheavy TeV) diquark scalar produced in the collisions of two up quarks at the LHC. Assuming that the diquark scalar decays int…
Composite quarks and leptons with embedded QCD
Benoît Assi, Bogdan Dobrescu
We construct a model of quark and lepton compositeness based on an gauge interaction that confines chiral preons, which are also charged under the weakly-coupled $SU(4)_{\…
