Introduction to quarks

  1. Oct 1, 2009 #1
    1. The problem statement, all variables and given/known data
    The ∑+ particle is a baryon with strangeness -1.

    How many quarks does the ∑+ particle contain?


    2. Relevant equations

    How many of the quarks are strange?

    3. The attempt at a solution
    I know it contains 3 quarks, 2 ups and 1 strange quark but I'm not sure how to work this out, for future reference, I'm just a little confused.

    Edit: just realised this is probably in the wrong section - apologies.

    A strange quark has a strangeness of -1. You know there are 3 quarks in a baryon and its strangeness is given as -1 so the answer from there should be obvious.
