We classify the meson and baryon long lived resonances considering quarks with electric charge 5/3 and $-4/3$ (in units of $vert evert$) predicted by some 3-3-1 models. Some of these exotic resonances have the usual electric charges $0,pm1$, others have $pm(3,4,5)$, and the lightest ones decaying only into leptons plus known resonances. We propose another heavy $SU(3)_H$ global symmetry under which hadrons involving only exotic quarks can be constructed.
Many new states in the charmonium and bottomonium mass region were recently discovered by the BaBar, Belle and CDF Collaborations. We use the QCD Sum Rule approach to study the possible structure of some of these states. In particular we identify the
We reconsider the question of electric charge quantization, which leads to the existence of a dark charge nontrivially unified with weak isospin in a novel gauge symmetry, $SU(3)_Cotimes SU(2)_Lotimes U(1)_Yotimes U(1)_N$, where $Y$ and $N$ determine
We report on a measurement of the top-quark electric charge in ttbar events in which one W boson originating from the top-quark pair decays into leptons and the other into hadrons. The event sample was collected by the CDF II detector in sqrt(s)=1.96
In this paper we investigate the Exotic Charmonium (EC) production in $gamma gamma$ interactions present in proton-proton, proton-nucleus and nucleus-nucleus collisions at the CERN Large Hadron Collider (LHC) energies as well as for the proposed ener
The tree-level partonic angular distribution of Standard Model $Wgamma$ production possesses a feature known as the Radiation Amplitude Zero (RAZ) where destructive interference causes the cross section to vanish. At the proton level the exact cancel
