Suppose we have a massless complex field in 3+1 spacetime where E^2 = P^2. Suppose that the only excitations that are possible are those that in some rest frame consist of an excitation of a pair of states p1 and p2 such that
p1 = -p2 and ιp1ι = ιp2ι = mc^2 = (+or-)E, and
the pair of states p1 and p2 couple (sum) together somehow.
In such a "rest frame", (with the right choice of constants), we would have functions like (?) ,
ψ+ = cos(x+α)exp(-iEt)exp(iθ+) and
Ψ- = cos(x+β)exp(iEt)exp(iθ-)
where exp(iθ+) and exp(iθ-) are phase factors and α and β are real numbers.
Momentum sums to zero and "rest" energy is mc^2?
If we could consider such a state that was made up of such a pair would the pair considered as one state transform in another Lorentz frame as a massive complex field?
Thanks for any help!
