For 10 points, identify these leptons which are 207 times more massive than electrons.
The experiment called TWIST studies the decays of polarized versions of these particles. Resistive plate chambers are often used in the detection system for these, and one of the two main LHC detectors is named for its ability to detect these particles. These unstable particles have an anomalous magnetic moment that is very sensitive to supersymmetric effects, while scientists have also investigated their ability to catalyze nuclear fusion. Seth Neddermeyer and Carl Anderson discovered them, and intially confused them for Yukawa's meson. For 10 points, identify these leptons which are 207 times more massive than electrons.
