Dark matter as ultralight axion-like particle in E6 × U(1)X GUT with QCD axion
Axion-like fields are naturally generated by a mechanism of anomaly cancellation of one or more anomalous gauge abelian symmetries at the Planck scale, emerging as duals of a two-form from the massless bosonic sector of string theory. This suggests an analogy of the Green–Schwarz mechanism of anomal...
