Hello all,
I have been racking my brain trying to figure out how to analyze a three body decay (lambda_c ---> kaon, pion proton). What I have done is taken the kaon on an arbitary axis and set the decay in a plane. Now I found out that the angles assumed by the pion and proton can be anything from collinear to wide open on a nearly uniform distribution. My problem is that I have three equations, 2 for p-conservation and one for e-conservation, but the only way I have been able to eliminate my variables has inevitably led to the problem of radicals I cannot simplify because of the energy relationship E = sqrt(m^2 + |p|^2). I don't know if anything I just said makes any sense, but I am lost.
My ultimate goal is to attain the 4-vector for each of the three particles and create a Dalitz plot based on the invariant masses of the pion-kaon and the proton-kaon. Please help if you can!
