“Isochronic” dynamical systems and nullification of amplitudes
(North-Holland, 2003)We construct the set of theories which share the property that the tree-level threshold amplitudes nullify even if both initial and final states contain the same type of particles. The origin of this phenomenon lies in ... -
On the triviality of higher-derivative theories
(North-Holland, 2012)The higher-derivative theories with degenerate frequencies exhibit BRST symmetry [V.O. Rivelles, Phys. Lett. B 577 (2003) 147]. In the present Letter meaning of BRST-invariance condition is analyzed. The BRST symmetry is ...
