This article uses the Einstein summation convention for tensor/spinor indices, and uses hats for quantum operators.In relativistic quantum mechanics and quantum field theory, the Bargmann–Wigner equations (or BW equations or BWE) are relativistic wave equations which describe free particles of arbitrary spin j, an integer for bosons (j = 1, 2, 3 ...) or half-integer for fermions (j = 1⁄2, 3⁄2, 5⁄2 ...). The solutions to the equations are wavefunctions, mathematically in the form of multi-component spinor fields. The spin quantum number is usually denoted by s in quantum mechanics, however in this context j is more typical in the literature (see references).They were proposed by Valentine Bargmann and Eugene Wigner in 1948, using Lorentz group theory, and building on the work of those who pioneered quantum theory within the first half of the twentieth century.
