The weak force is the force that causes a quark to change into a different type of quark or change a quark’s charge. It is one of the three fundamental forces in the Standard Model of Particle Physics —the forces that cannot be reduced to an even smaller force.

Among all four nuclear forces, the weak nuclear force is highly interesting. The weak force or weak nuclear force is the only fundamental force that is aware of the spin of the particle and can categorise the particles into either particle or antiparticle. According to classical physics, the spin of the object is considerably easy, i.e., it says ei...
In the 1950s scientists tested the interactions between both strong force and electromagnetic forces and realised that both of them are not explaining anything regarding the spin of the object under observation. However, in 1956 two theoretical physicists, Tsung Dao Lee and Chen-Ning Yang studied these with details and experimented with whether the...
Back in the 1930s, as physicists were just deriving the quantum theory of the much stronger electromagnetic force, they came up with an explanation. The photon, the quantum particle that transmits electromagnetism, has no mass i.e., it is a massless element, so it is easy to make photons and transmit them over large distances, sometimes even infini...

The Weak Interaction. The weak interaction accounts for many decays in particle physics, e.g. μ. − → − e ̄νe νμ. − τ − → e ̄νe ντ π. + → − μ ̄νμ n → − pe ̄νe. Characterised by long lifetimes and small interaction cross-sections.
