Archived Strong interaction and strangeness

  1. May 8, 2013 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    This one has confused me,
    I know that Baryon number has to be conserved so X has to be a baryon.
    I can see how charge is conserved
    3. The attempt at a solution

    answer1_zps2fdc5696.jpg

    I know this is the strong interaction. Is it a collision?
    Is that where the energy for the extra two quarks come from?
    Is there some strange conservation rule at play.
    I know I made them all blue quarks but I only had one pen

    Thanks and sorry for two question in one evening

    First, it has to be a baryon, to conserve baryon number.
    Second, it has to be negatively charged to conserve charge.
    Third, it has to have a strangeness of -3 to conserve strangeness (strong interaction, so strangeness is conserved)

    So, to be a negatively charged baryon with a negative strangeness of 3, it must have quark structure sss

    So particle X is an Ω-

    I think the mistake made is saying that K0 is anti-down strange. That is the anti-K0
    The K0 is down anti-strange
