Only left-handed fermions experience the weak nuclear force

Weak nuclear force is not really a “force.” Weak nuclear “force” facilitates transformations between the first column \left[ u(L), c(L), t(L) \right] and the second column \left[ d(L), s(L), b(L) \right] of quarks, and the first column \left[ \nu_e (L), \nu_\mu (L), \nu_\tau (L) \right] and the second column \left[ e (L), \mu (L), \tau (L) \right] of leptons as shown in the fermion table below.

What this means is that only left-handed fermions experience the weak nuclear force.

All particles in the table below have spin=1/2. The elementary particles with spin=1/2 are known as fermions. This is why the table below is also known as the fermion table.

In the fermion table below the “L” signifies left-handed and “R” right-handed chirality.

Fermion table


u : up-quark
c : charm-quark
t : top-quark
d : down-quark
s : strange-quark
b : bottom-quark
\nu_e : electron type neutrino
\nu_\mu : muon type neutrino
\nu_\tau : tau type neutrino
e : electron
\mu : muon
\tau : tau

Note that there are no right-handed neutrinos.
