Particle question

  1. Apr 13, 2007 #1
    this isn't really a problem, just a question.
    with baryons, what exactly is the difference between the different quark combonations?
    for example, a proton had two up quarks and a down but so does the delta, or one of them, i guess. shouldn't that mean that they are the same particle?
    how are they different?

    2. Relevant equations


    3. The attempt at a solution

    the only thing i could thing of was the different order that the quarks are it, or a difference in spin. it wouldn't be a difference in charge, though, because the fractional charges in the quarks are what determines the charge of the whole particle, right?:grumpy:

    The three quark spins in the nucleon add up to spin 1/2,
    and to spin 3/2 in the Delta.
