Exchange particles

  1. Jan 7, 2007 #1
    Well its not really a homework question but I have looked through the tutorials and am still at a loss.

    1. The problem statement, all variables and given/known data
    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?


    2. Relevant 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.
