Casimir introduced a trick that reduces the problem of finding S-Matrix elements to the problem of calculating traces of operators symbolized by this letter.
Casimir introduced a trick that reduces the problem of finding S-Matrix elements to the problem of calculating traces of operators symbolized by this letter. This letter appears in the Breit-Wigner distribution where it stands for the resonance width, and the frequency of Larmor precession is equal to the magnetic field over two pi times a quantity symbolized by this letter. A quantity symbolized by this letter equals 5/3 for monatomic ideal gases and is the ratio of the constant pressure heat capacity to the constant volume heat capacity. Another quantity symbolized by this letter is one over the root of one minus velocity squared and appears in the formulas for length contraction and time dilation. For 10 points, name this letter which labels the most energetic rays in the electromagnetic spectrum.
