1. A lambda particle decays into a proton and pion and it is observed that the proton is left at rest.
a. what is the energy of the pion?
b. what is the energy of the original lambda? m of lambda = 1116MeV/c^2, m of proton = 938 MeV/c^2, and m of pion = 140 MeV/c^2
Conservation of energy and momentum. E[tex]\lambda[/tex] = E [tex]\rho[/tex] + E[tex]\pi[/tex], P [tex]\lambda[/tex] = P[tex]\rho[/tex] + P[tex]\pi[/tex]
Lorentz Transformation
I tried breaking down conservation of energy and momentum so solve for what i need but i can't seem to get it right. I've tried using lorentz transformation with the energy and momentum but no lucky either.
Any help is appreciated!
Thanks
