Karpio, Andrzej
Hilbert spaces for massless particles with nonvanishing helicities.
(English)
[J] Ann. Inst. Henri Poincaré, Phys. Théor. 70, No.3, 295-311 (1999). ISSN 0246-0211

Summary: The paper contains a complete description of the phase spaces for massless particles with different helicities. Explicit formulae for reproducing kernels for investigated Hilbert spaces are given. The author demonstrates a full symmetry between scalar products and reproducing kernels which are strictly related to the twistor propagator.
