Tau decay modes

WebTau Particle Decay Modes Description. The tau data frame has 60 rows and 2 columns. The tau particle is a heavy electron-like particle discovered in the 1970's by Martin Perl … Webdetected via their decay products. The main decay modes of the tau are shown in the chart to the right. The hadronic decays are grouped according to number of charged decay products (prongs). The main hadronic decay modes involve a mixture of charged and neutral pions. The neutral pions have a mean lifetime of just 8.4 x 10-17 s, decaying
