The standard model top must have charge 2\/3, but a simple extension (adding a fourth quark generation) would give an exotic quark with mass 175 GeV, pushing the SM top quark up to over 200 GeV. It would have 4\/3 charge. Clearly, if we want to call a top a top, we need to measure its charge.<\/p>\n<p>Per and Zeynep showed that the quark we call &#8220;top&#8221; is, indeed, very standard model-like in its charge.
