1. The problem statement, all variables and given/known data hello everybody I am new too these forums and am looking for a little help on a problem. I don't want anyone to give me the answer so i will just post the basic question and any help would be appreciated. If an uncharged meson decays into two charged pions in the presence of a magnetic field. If the mass of a pion, magnitude of the magnetic field and the radius of the pions path are all known, I need to find the pions momenta and speed, as well as the mass of the meson. thanks for any help! 2. Relevant equations conservation of reletivistic momentum and energy E=gamma mc^2 p=gamma mv a=v^2/R 3. The attempt at a solution I am a little lost on how to get started on the question. I wrote out the equations for conservation of momentum and energy, but am a little confused on how to integrate the magnetic field and circular motion parts of the question.
