Observability of an ultraheavy diquark decaying into vectorlike quarks at the LHC
Daniel C. Costache, Calin Alexa, Anca M. Dinu +4
We present a comprehensive analysis of the discovery reach and exclusion limits for an ultraheavy diquark scalar (7-9.5 TeV) decaying into a pair of vectorlike quarks (1.5-2 TeV) a…

HL-LHC sensitivity to an ultraheavy diquark in the channel
Matei S. Filip, Calin Alexa, Daniel C. Costache +3
We study the HL-LHC sensitivity to an ultraheavy diquark produced in up-quark fusion and decaying as , . For fully hadronic decays of th…

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…
