Time-symmetric quantization of relativistic fields. 1. Complex fields, massless gauge fields and gravitons

In the standard formulation of quantum field theory (QFT), where there are only positive energy particles and antiparticles, charge vacuum diverge, which, due to existence gravity, leads inconsistency (cosmological constant problem). article, it is shown that in Stueckelberg-Feynman (SF) interpretation, antiparticles described as negative moving backward time, zero-point complex fields absent no cosmological problem. However, until now was believed SF interpretation probabilities incompatible with QFT. presented a new QFT on basis form time-symmetric quantization (TSQ), probability states positive. TSQ, consequences taken into account consecutively that: a) sign norm changes wave function, not probabilities; b) expression time integrals through forward sign; c) ordering operators symmetric writing them usual diagram technique. For this reason, TSQ correctly describes known observable effects. results unification models change, particular, even broken supersymmetry between fields; modes string theories, which allows include but conformal anomaly dimension space can be arbitrary.
