Large primordial non-Gaussianity from transient turns in Higgs- inflation
Flavio Pineda, Luis O. Pimentel
We investigate the generation of primordial non-Gaussianities in multifield Higgs-- inflation, focusing on the effects of transient turning trajectories in the hyperbolic fiel…

Isocurvature-induced features in multi-field Higgs- inflation
Flavio Pineda, Luis O. Pimentel
We study primordial perturbations in Higgs-- inflation in the presence of non-minimal kinetic mixing between the Higgs field and the scalaron. By numerically solving the multi…

Non-perturbative approach for scalar particle production in Higgs- inflation
Flavio Pineda, Luis O. Pimentel
We investigate the non-perturbative production of scalar particles within the Higgs- inflation model, focusing on a massive spectator field that interacts gravitationally via…
