Singlet charge 2\/3 quark hiding the top: Tevatron and LEP implications
If c and t quarks are strongly mixed with a weak singlet charge 2/3 quark, BR(t\to \ell\nu + X) could be suppressed via the t\to cH^0 mode thereby the top quark could still hide below M_W, whereas the heavy quark signal observed at the Tevatron is due to the dominantly singlet quark Q. This may occu...
