Solving Weak Interactions: W- vs W+

Click For Summary
SUMMARY

The discussion focuses on the distinctions between weak interactions involving W- and W+ bosons, particularly in the context of beta decay. It is established that beta minus decay involves the W- boson, while beta plus decay involves the W+ boson. The confusion arises in identifying which weak interaction corresponds to which boson in unknown reactions. Charge conservation plays a crucial role in determining the correct boson involved in these interactions.

PREREQUISITES
  • Understanding of weak interactions in particle physics
  • Familiarity with W and Z bosons

Well its not really a homework question but I have looked through the tutorials and am still at a loss.

Homework Statement


During weak interactions the particle exchanged is either W- W+ or Z0. The thing is, I get confused which weak interactions involve W- and which involve W+. I know beta minus decay is W- and beta plus W+ but how do I work it out for an unknown reaction?


Homework Equations


Is charge conservation involved, if so how?

Any guidance would be much appreciated.

W bosons are primarily seen in quarks flavour changes. I take it you are doing A-levels, or equivalent. If you are don't worry about the rules and just learn the few reactions you're given. I say this because W bosons can either be emited or absorbed which makes it a bit more difficult.
