    en.wikipedia.org/wiki/Euler's_constant

    Euler's constant (sometimes called the Euler–Mascheroni constant) is a mathematical constant, usually denoted by the lowercase Greek letter gamma (γ), defined as the limiting difference between the harmonic series and the natural logarithm, denoted here by log:

    en.wikipedia.org/wiki/Gamma_function

    The definition for the gamma function due to Weierstrass is also valid for all complex numbers except non-positive integers: = = (+) /, where is the Euler–Mascheroni constant. [1] This is the Hadamard product of 1 / Γ ( z ) {\displaystyle 1/\Gamma (z)} in a rewritten form.

    An example for such a particle [9] is the spin ⁠ 1 / 2 ⁠ companion to spin ⁠ 3 / 2 ⁠ in the D (½,1) ⊕ D (1,½) representation space of the Lorentz group. This particle has been shown to be characterized by g = ⁠− + 2 / 3 ⁠ and consequently to behave as a truly quadratic fermion.
