Single Vectorlike Quark Production at the LHC
Roberto Barcelo, Adrian Carmona, Mikael Chala +2
A gluon resonance G of mass below 1 TeV could be the origin of the t\bar{t} forward-backward asymmetry observed at the Tevatron provided that new decay modes G->\bar{q}Q, with q a…
Stealth gluons at hadron colliders
Roberto Barcelo, Adrian Carmona, Manuel Masip +1
We find that a heavy gluon G of mass 800-900 GeV with small, mostly axial-vector couplings to the light quarks and relatively large vector and axial-vector couplings to the top qua…
Gluon excitations in t tbar production at hadron colliders
Roberto Barcelo, Adrian Carmona, Manuel Masip +1
We argue that a relatively light massive gluon with mass <= 1 TeV, small purely axial couplings to light quarks and sizable vector and axial couplings to the top quark can reproduc…
