This interaction can change the flavor of quarks - in other words, it is responsible for the conversion of quarks into other types of quarks, which is seen in beta decay.
In quarks, the strength of this interaction is governed by the Cabibbo angle. One mechanism governed by this interaction can couple to any non-gluon particle; that neutral current interaction provides the mechanism for scattering of neutrinos by ordinary matter. This interaction can change the flavor of quarks - in other words, it is responsible for the conversion of quarks into other types of quarks, which is seen in beta decay. This force is mediated by the W and Z bosons. For 10 points, name this fundamental force that at high energies merges with the electromagnetic force.
