a. what particles are involved when an up quark changes to a down quark?

b. what particles are involved when an down quark changes to an up quark?

Answer 1

Answer #1

a. what particles are involved when an up quark changes to a down quark?

β- decay, which involves a down quark changing into an up quark where a neutron becomes a proton and an electron.

b. what particles are involved when an down quark changes to an up quark?

β+ decay, which involves an up quark changing into an down quark where a proton becomes a neutron and a positron.

In the quark model of fundamental particles, a proton is composed of three quarks: two "up" quarks, each having charge +2e/3, and one "down" quark, having charge -e/3. Suppose that the three quarks are equidistant from one another. Take the distance to be 1.20×10-15 m and calculate the potential energy of the subsystem of two "up" quarks. (MeV)
