Problem 34 Hard Difficulty

The quark compositions of the $\mathrm{K}^{0}$ and $\Lambda^{0}$ particles are $\mathrm{d} \overline{s}$ and uds, respectively. Show that the charge, baryon number, and strangeness of these particles equal the sums of these numbers for their quark constituents.

Answer

$=-1$
Hence charge, baryon number and strangeness of $\mathrm{K}^{0}$ and $\Lambda^{0}$
Equal the sum of these numbers for the quark constituents.

So here this question you are looking at you tree different properties off the following particles first e k on same and the London not particle, which is a very right at the treatment properties they're looking at is accurate strangeness bear no number and finally church. In our case, Thebe properties of the particles is known to be following that ISS the strangeness value off key on this one for, uh, zero es minus one. So he supposed if one barrel number is cereal for the killing and plus one for the longer or not? Finally, the church for both particles is they're both neutral. Now we're given that close to it. Quote content, right for killing is don't we found anti strange When you're in for the lumber, Baron is made up off up don't and strange quote and we want to see whether their properties can be, uh can we re establish by simply looking at the Clark properties. So the cock puppet issue first got a look at would be the me zones for the K aunts. But clocks, which is down at anti strange. So for Tom Parker is cereal strangeness. It has a very one number off. It's a church off a minus. What did you for the for? Any strange and say strangers off plus one barrel number off minus winter. Since it is an antique watch charge off. Thus what? And then we see the charge itself will cancel out to give us the rule that is school. The barrel number. All right, we'll cancel out to give out zero, which is also good. Finally, you strange. Just value plus one plus zero. Give us last one. And so actually shows that quite content actually shows improves the properties for chaos. Measles? You don't moving on to d loved? Uh, not very on. We gonna look at the clock first, then we already have two. Don't talk over here on the first column. Go to ready of Cook and Andy shrieks cook. Right, So that court has little strangeness. Bear number off, plus one in a church off plus two tests for the street clock. It has striations off minus one. Burial number off. Plus wanted in church off minus. What? So we're gonna go where we need this tree columns. All right. ST. Columns 12 tree GST contents for Lambda Berro, The church are heading up together. My plus two tits minus wanted. My just want It gives us zero, which is good. The barrel number plus one took for all of them. Gives us plus one deed. Strangeness is zero plus You plus minus one gives us minus one. So it also proves the properties right they receive for our Lambda, not burial.
