In Beta Decay, which force exchange particle is involved and why

a) gluon
b) photon
c) W+
d) W-
e) pie-meson

1 answer

c) W+

In Beta Decay, the weak nuclear force is responsible for the transformation of a neutron into a proton or vice versa. The force carrier for the weak nuclear force is the W boson, which comes in two varieties - W+ and W-. These particles are responsible for mediating the weak force interactions that govern Beta Decay processes.
