HIGHLIGHTS
- who: Antonio Enea Romano from the Theoretical Physics Department, CERN, Geneva, Switzerland , Instituto de Fisica, Universidad de Antioquia, Medellin, Colombia have published the Article: Model-independent approach to effective sound speed in multi-field inflation, in the Journal: Eur. Phys. J. C
- what: The authors show that the evolution of that effective adiabatic mode is correctly described within the formalism of momentum-dependent effective sound speed, discussing the notion of effective single-field theory for inflationary perturbations and providing a set of numerical calculations corresponding to specific two-field inflationary models that have attracted considerable . . .
