THEORY OF THE τ LEPTON ANOMALOUS MAGNETIC MOMENT

    https://doi.org/10.1142/S0217732307022694Cited by:103 (Source: Crossref)

    This paper reviews and updates the Standard Model prediction of the τ lepton g-2. Updated QED and electroweak contributions are presented, together with new values of the leading-order hadronic term, based on the recent low energy e+ e- data from BaBar, CMD-2, KLOE and SND, and hadronic light-by-light contribution. The total prediction is confronted to the available experimental bounds on the τ lepton anomaly, and prospects for its future measurements are briefly discussed.
