Consider the cross-section of the process e + e f + f as a
Question:
Consider the cross-section of the process e+e– → f +f – as a function of the centre of mass energy √s near a resonance of mass MR and total width Γ. Assuming that the Breit–Wigner formula correctly describes its line shape, calculate its integral over energy (the ‘peak area’). Assume Γ / 2 << MR.
