In QED, the elementary charge squared over 12 pi cubed gives the one-loop contribution to a quantity denoted by this letter, which equals the derivative of the coupling constant with respect to the log of the energy scale. In a plasma, this letter denotes the ratio of plasma pressure to magnetic pressure. The inverse of Boltzmann's constant times temperature is denoted by thisletter. In special relativity, this letter denotes the ratio of an object's velocity to the speed of light.
