When the e+e" center of mass energy is varied, one observes a series of peaks in the total cross section for some specific channels e+e" —¥ hadrons. WebUse the Feynman diagram to describe the interaction between a proton and a neutron and apply the uncertainty principle to approximate the mass of the meson. In making the approximation, assume that the meson was initially at rest and that the distance between the proton and neutron is 1.5x10^-15 meters at the time of "collision". + SHOW MORE
