Question

Kaon

1) What quarks is the baryon made of?

2) What is the mass of the baryon? (Mass might be called "rest mass," and will probably be given in units of MeV/c^2 or GeV/c^2.)

3) What is the sum of the masses of the quarks that make up the baryon? Does this equal the baryon's mass? If not, why are the masses different? (Note that you'd need the units of the quark masses to be the same as the units of the baryon mass, either MeV/c^2 or GeV/c^2. You can convert between the two easily because 1 GeV/c^2 = 1000 MeV/c^2, or you can also just google "what is x GeV/c^2 in MeV/c^2?" and google will convert it for you.)

4) How long will the baryon live before decaying? (i.e. what is the baryon's lifetime?)

5) What will the baryon decay into? (There are often times many different ways a baryon can decay; just give one example.)

Answer 1

1)Baryons are composite particles made of three quarks, rather than mesons, which are composite particles made of one quark and one antiquark. ... For instance, a proton is made of two up quarks and one down quark, while its relating antiparticle, the antiproton, is made of two up antiquarks and one down antiquark
