Homework Statement
What is the minimum proton energy needed in an accelerator to produce antiprotons [itex]\bar{p}[/itex] by the reaction
[tex]p+p \to p+p + (p+\bar{p})[/tex]
The mass of a proton and antiproton is m_p.
Homework Equations
The Attempt at a Solution
I said 2 m_p c^2 because that is the sum of the rest energies of a proton and an antiproton. Apparently that is wrong.
