Given some state \left|\psi\right\rangle, and two operators \hat{A} and \hat{B}, how do you prove that if \langle\psi|\hat{A}|\psi\rangle = \langle\psi|\hat{B}| \psi\rangle then \hat{A} = \hat{B} ?

Is it correct that applying charge conjugation to matter gives us antimatter? This post claims that it is the CP operation that does... http://blogs.uslhc.us/symmetry-in-physics-pt-2-discrete-symmetries-and-antimatter Which is correct?

Is it possible to integrate \int \frac{1}{1+e^{-x^2}} dx

Thanks a lot for the help :) I sorted it in the end by finding the energies in the ZMF after the decay and then using the doppler shift to transform them back into the lab frame.

Homework Statement A (pi)0 meson whose rest mass is 135 MeV/c2 is moving with a kinetic energy of 1 GeV. It decays in flight into two photons whose paths are along the direction of motion of the meson. Find the energies of the two photons. Homework Equations Lab Frame: The...
