Question

In a fixed-target experiment positrons are fired at a target of electrons at rest. What positron energy is required to produce a Z (mZ = 91.188 GeV)?

Answer 1

Step-by-step explanation:

electron rest mass = 0.511MeV/C²

postion rest mass = 0.511MeV/C²

boson rest mass = 91.188GeV/C²

= 91188 MeV/C²
