W bosons are the exchange particles for the weak interaction.Unlike photons W bosons have a non-zero rest mass. They have a short range of ≤ 0.001 fmThey may be negative W- bosons or positive W+ bosons.
A W- boson decays into a β- particle and an antineutrino.A W+ boson decays into a β+ particle and a neutrino.
At sufficiently high energies protons collide with anti-protons and produce W bosons along with the photons when they annihilate each other.
