Homework Statement
At HERA 30 GeV electrons collided head on with 820 GeV protons. Calculate the invariant mass of ep collisions.
(masses: e=0.0005GeV, p=0.938GeV)
Homework Equations
M^2 = (E1 + E2)^2 - (p1 + p2)^2 ?
The Attempt at a Solution
I know the numerical answer to this question is 314GeV, but so far I haven't been able to get it. I've tried plugging in the known values to the above equation, using E^2 = p^2 + m^2 to find momentum, but obviously didn't get the right answer.
What should I be doing?
Thanks!
