Problem 36 Medium Difficulty

What is the electrical charge of the baryons with the quark compositions (a) $\overline{\mathrm{uu} \mathrm{d}}$ and (b) $\overline{\mathrm{u}} \mathrm{dd}$ ? What are these baryons called?

Answer

$(a) \text{Charge}= -e, \text{particle is an antiproton} (b) \text{Charge}= 0, \text{particle is an antineutron} $

So I find charges for moving burials. We're given the content rights, which is anti up and up and down for by ante up and she don't you don't. So the properties off ante up is as follows its a charge off negative to touch. It's on the other end for the anti Don't. It's church is a positive one toe eat so you can actually find out waste He told her church over here By adding up to up plus one down, we should get negative e for the other case. This will be negative 2/3 plus want plus wanted to get zero You would see that this is actually quite familiar, right? Negative. Up, up, down Since our proton is actually up, up, down and all Neutron, is it closed toe g up downtown. But, you know, case all of these are turned into anti quarks. So, in fact, this would be court and t proton. Right? Because you are converting all the clocks in the proton to an anti quark. Same. We've the other case. This is an anti you trump
