Homework Statement
A particle with mass M decays into 2 particles of equal mass m.
1: Calculate the speed of the decay particles
2: Concider the case ρ->[tex]\Pi\Pi[/tex]: M = 770 MeV and m[tex]\Pi[/tex]= 140 MeV
Homework Equations
m = [tex]\gamma[/tex]m(restmass) ?
The Attempt at a Solution
I suppose M/2 is restmass and found an expression for the speed. However since the mass increase when the speed approaches the speed of light, this would imply that m is a larger number than M/2. But in task 2, it says M/2 is larger than m[tex]\Pi[/tex], which implies I've done something wrong.
Please help me solve this task or find out what i did wrong.
