Strong interaction and strangeness

[mrcotton]

Homework Statement

Homework 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

The Attempt at a Solution

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
