Very Special Relativity and Noncommutative Space-Time

The Very Special Relativity (VSR) introduced by Cohen and Glashow [16] has a robust mathematical realization on noncommutative space-time, in particular on noncommutative Moyal plane, with light-like noncommutativity [35]. The realization is essentially connected to the twisted Poincare algebra and its role as symmetry of noncommutative space-time and the corresponding quantum field theories [11, 12]. In our setting the VSR invariant theories are specified with a single deformation parameter, the noncommutativity scale Lambda(NC). Preliminary analysis with the available data leads to Lambda(NC) >= 1 - 10 TeV.
