Shapes of the Cosmological Low-Speed Collider

Jazayeri, Sadra, Renaux-Petel, Sébastien, Werth, Denis

Understand

Massive particles produced during inflation leave specific signatures in soft limits of correlation functions of primordial fluctuations.

When the Goldstone boson of broken time translations acquires a reduced speed of sound, implying that de Sitter boosts are strongly broken, we introduce a novel discovery channel to detect new physics during inflation, called the cosmological low-speed collider signal.
This signal is characterised by a distinctive resonance lying in mildly-soft kinematic configurations of cosmological correlators, indicating the presence of a heavy particle, whose position enables to reconstruct its mass.
We show that this resonance can be understood in terms of a non-local single field effective field theory, in which the heavy field becomes effectively non-dynamical.
