The CDF Measurement of the Top Quark Charge using the Top Decay Products in Lepton + Jet channel

We report on the measurement of the top quark charge using the decay products of the top quark. There are three main components to this measurement: determining the charge of the W (using the charge of the lepton), pairing the W with the b jet to ensure that they are from the same top decay branch and finally getting the flavor of the b jet using the Jet Charge algorithm. Using 5.6fb of data we found the result to be consistent with the standard model, while excluding an exotic quark hypothesis with 99% confidence.
