Spin 1/2 and Invariant Coefficients II. Massless
Richard Shurtleff
A `covariant' field that transforms like a relativistic field operator is required to be a linear combination of `canonical' fields that transform like annihilation and creation op…

Massless Particle Fields, with Momentum Matrices
Richard Shurtleff
Nontrivial translation matrices occur for spin (A,B)+(C,D) with |A-C| = |B-D| = 1/2, necessarily associating a (C,D) field with a spin (A,B) field. Including translation matrices i…

Massive Particle Fields, with Momentum Matrices
Richard Shurtleff
It is well known that an essentially unique free massive particle field of given spin can be constructed as a linear combination of the annihilation and creation operators for free…
