# Looking for info on the average decay energy of the Tauon

I am interested in finding the average decay energy of the Tauon. I am interested in the average net decay energy as a function of the known branching ratios of the tauon decay as well as the average actual decay energy in electron volts.

• What do you mean by decay energy? If you just mean the total energy of the decay products, the answer is $m_\tau$, the mass of the particle, just as it is for every particle. – Chris Jan 25 '18 at 10:29
