weak force

From Big Think, Feb. 6, 2023: For the first time, the proton’s size and structure was measured using Fermilab’s MINERVA detector by studying proton/neutrino interactions. This new method, which studies weak force interactions, is a first step in which scientists can use to better understand the laws of the Universe.

To understand the universe, you need to understand the different forces that govern it. In this 11-minute video, episode 6 of Subatomic Stories, Fermilab scientist Don Lincoln explains the nature of the forces that govern the microcosm.

The subatomic world is governed by three known forces, each with vastly different energy.  In this video, Don Lincoln takes on the weak nuclear force and shows why it is so much weaker than the other known forces.

Weak force decays change the identity of a particle as well as its electrical charge. Scientists are looking for identity-changing decays with no change in electrical charge, which would point to new physics.
