Homework Statement
a) [Solved] What is the threshold energy in the center of mass for production of an antiproton in a proton-proton collision? Make sure quantum numbers are conserved. (This one was easy and I manage to solve it)
b) In a fixed target experiment calculate the proton beam energy corresponding to this threshold and the energy of the produced anti-proton in this laboratory frame.
Homework Equations
The Attempt at a Solution
On b) is where I'm a little stuck. On a) I simply squared the sum of the four-momenta and putted equal to (E_cm)^2 / c^2. Where E_cm = 3mc^2
But when I get an energy, how do I convert that to the lab-frame?
