Anisotropic Trispectrum of Curvature Perturbations Induced by Primordial Non-Abelian Vector Fields
Nicola Bartolo, Emanuela Dimastrogiovanni, Sabino Matarrese +1
Motivated by the interest in models of the early universe where statistical isotropy is broken and can be revealed in cosmological observations, we consider an SU(2) theory of gaug…

Anisotropic bispectrum of curvature perturbations from primordial non-Abelian vector fields
Nicola Bartolo, Emanuela Dimastrogiovanni, Sabino Matarrese +1
We consider a primordial SU(2) vector multiplet during inflation in models where quantum fluctuations of vector fields are involved in producing the curvature perturbation. Recentl…
