Using the massive helicity formalism, we calculate the five-body average square amplitude of the decays [Formula: see text] [Formula: see text] within the Standard Model (SM), we then introduce a dimension-five effective vertex [Formula: see text] in order to determine the feasibility of imposing limits on the tau anomalous magnetic dipole moment [Formula: see text] via the current or future experimental measurements of the branching ratio for the decay [Formula: see text].

Twenty paired 14C and U/Th dates covering most of the past 50,000 yr have been obtained on a stalagmite from the Cango Caves in South Africa as well as some additional age-pairs on two stalagmites from Tasmania that partially fill a gap between 7 ka and 17 ka ago. After allowance is made for the initial apparent 14C ages, the age-pairs between 7 ka and 20 ka show satisfactory agreement with the coral data of Bard et al. (1990, 1993). The results for the Cango stalagmite between 25 ka and 50 ka show the 14C dates to be substantially younger than the U/Th dates except at 49 ka and 29 ka, where near correspondence occurs. The discrepancies may be explained by variations in 14C production caused by changes in the magnetic dipole field of the Earth. A tentative calibration curve for this period is offered.
