of the weak force. Weak isospin plays the same role in the weak interaction with W ± as electric charge does in electromagnetism, and color charge in the strong interaction; a different number with a similar name, weak charge, discussed below, is used for interactions with the Z 0.
Measurements in 2017 give the weak charge of the proton as 0.0719 ± 0.0045 . [4]The weak charge may be summed in atomic nuclei, so that the predicted weak charge for 133 Cs (55 protons, 78 neutrons) is 55×(+0.0719) + 78×(−0.989) = −73.19, while the value determined experimentally, from measurements of parity violating electron scattering, was −72.58 .
In quantum mechanics, physicists often use the terms "force" and "interaction" interchangeably; for example, the weak interaction is sometimes referred to as the "weak force". According to the present understanding, there are four fundamental interactions or forces: gravitation, electromagnetism, the weak interaction, and the strong interaction ...
Note that we have to redefine a new U(1) symmetry of weak hypercharge, different from QED, in order to achieve the unification with the weak force. The electric charge Q , third component of weak isospin T 3 (also called T z , I 3 or I z ) and weak hypercharge Y W are related by Q = T 3 + 1 2 Y W , {\displaystyle Q=T_{3}+{\tfrac {1}{2}}Y_{\rm ...
The weak mixing angle or Weinberg angle [2] is a parameter in the Weinberg–Salam theory of the electroweak interaction, part of the Standard Model of particle physics, and is usually denoted as θ W.
The nuclear force is distinct from what historically was known as the weak nuclear force. The weak interaction is one of the four fundamental interactions, and plays a role in processes such as beta decay. The weak force plays no role in the interaction of nucleons, though it is responsible for the decay of neutrons to protons and vice versa.
bosons (see weak mixing angle), each vertex factor includes a factor , where is the third component of the weak isospin of the fermion (the "charge" for the weak force), is the electric charge of the fermion (in units of the elementary charge), and is the weak mixing angle.
The Standard Model of particle physics is the theory describing three of the four known fundamental forces (electromagnetic, weak and strong interactions – excluding gravity) in the universe and classifying all known elementary particles.
