What does the Lorentz factor represent?
The Lorentz factor can be understood as how much the measurements of time, length, and other physical properties change for an object while that object is moving.
What you have named $r^2$ is indeed k …

Parity transformation on fermionic bilinears
In the Fermi weak theory we have the fermion bilinears which look like
$$
V_\mu = \bar{\psi} \gamma_\mu\psi
$$
$$
A_\mu = \bar{\psi} \gamma_\mu \gamma_5 \psi
$$
Under a parity transformation
$$
x = (x …
