Asymmetry in momentum space: restoring invariance of -field theory
Tadeusz Adach, Andrea Bevilacqua, Jerzy Kowalski-Glikman +1
The positive and negative energy modes of a field theory in -Minkowski/-Poincaré noncommutative spacetime have very different symmetry properties. This can be understood geom…
Yang model revisited
S. Mignemi
A long time ago C.N. Yang proposed a generalization of the Snyder model to the case of a curved background spacetime, based on an algebra isomorphic to , which includes as…
Amplitude prescriptions in field theories with complex poles
Damiano Anselmi, Fabio Briscese, Gianluca Calcagni +1
In the context of field theories with complex poles, we scrutinize four inequivalent ways of defining the scattering amplitudes, each forfeiting one or more tenets of standard quan…
