Abstract

• General single field inflation • From multi-field setup: by integrating out heavy field • Non-trivial c_s: footprint of heavy physics • Features in the power spectrum (S_2,int) and bispectrum (S₃) • Heavy quanta extract kinetic energy • Non-trivial, oscillatory correlated features • General slow-roll scheme • Terms with more derivatives → field redefinition • More complete 1st order bispectrum • Running of f_NL • Sensitive probe of early universe physics • Non-trivial evolution after horizon crossing.
