Which Lepton Processes are Most Probable?

Click For Summary
SUMMARY

The discussion focuses on comparing the probabilities of three lepton processes involving electron-positron annihilation. The processes are: 1) e+ + e- → νμ + νμ&bar;, 2) e+ + e- → νμ + νe&bar;, and 3) e+ + e- → νe + νe&bar;. The discussion emphasizes the necessity of determining the feasibility of these reactions and constructing Feynman diagrams to visualize the interactions, as some processes may be impossible while others can have multiple representations.

Homework Statement



Compare the probabilities for the following processes to happen:

1. e^+ + e^- \to \nu_\mu + \bar{\nu}_\mu
2. e^+ + e^- \to \nu_\mu + \bar{\nu}_e
3. e^+ + e^- \to \nu_e + \bar{\nu}_e

The Attempt at a Solution



I really have no idea how to solve this. Any help will be appreciated.

There are really two parts to this. First, try to see if any of those reactions is impossible (at least one is).

Secondly, for any or all reactions that are possible, you can try to draw the Feynman diagrams for those reactions. Some reactions may have more than one diagram; you need to find all of them (at least, all the diagrams with no loops).
