Hi,
Does anyone out there know the rules for mesons when it comes to the particle/antiparticle combinations? Is it simply like an up and anti-up quark that makes up a meson or is it like up and anti-down or down and anti-up? Or can it even be other combinations of the six quarks?
Also I have a question about baryons. I know that these are made up of three quarks, like up up down for a proton and a down down up for a neutron. Well, can it be the combination of any three types of quarks, like up up up or something like up down charm sttrange or some other combination? If someone can answer this and possibly show all of the possible combinations of quarks and anti-quarks in mesons and the possible combinations of quarks when it comes to baryons, I would really like to hear from you so I can be a little more informed than I already am. Another question is is that with protons and neutrons for example, if you have an anti-proton (a P with a bar over the top...called p-bar right? and an anti-neutron, a N with a bar over the top of it, do all of the signs change like the charge of an up quark like +2/3 turning into a -2/3 (which would be like an anti-up quark) or a -1/3 (which would be like an anti-down quark) turning into a +1/3 charge?
I would appreciate it if anyone out there would try and give a stab at the questions I have just presented.
Thank you,
