Exact bispectra in strongly mixed multifield inflation
Lucas Pinol
Using the effective field theory of inflationary fluctuations extended by a massive isocurvature scalar, at unit sound speed, we compute the primordial bispectra generated by every…
New exact bispectrum shapes in multifield inflation
Lucas Pinol
Using the effective field theory of multiple inflationary fluctuations, we present the first analytical calculation of the primordial bispectrum in which the quadratic mixing betwe…
Cosmological Correlators with Double Massive Exchanges: Bootstrap Equation and Phenomenology
Shuntaro Aoki, Lucas Pinol, Fumiya Sano +2
Using the recently developed cosmological bootstrap method, we compute the exact analytical solution for the seed integral appearing in cosmological correlators with double massive…
Borel resummation of secular divergences in stochastic inflation
Masazumi Honda, Ryusuke Jinno, Lucas Pinol +1
We make use of Borel resummation to extract the exact time dependence from the divergent series found in the context of stochastic inflation. Correlation functions of self-interact…
Cosmological Flow of Primordial Correlators
Denis Werth, Lucas Pinol, Sébastien Renaux-Petel
Correlation functions of primordial density fluctuations provide an exciting probe of the physics governing the earliest moments of our Universe. However, the standard approach to…
Inflationary flavor oscillations and the cosmic spectroscopy
Lucas Pinol, Shuntaro Aoki, Sébastien Renaux-Petel +1
Inflationary scenarios motivated by high-energy physics generically contain a plethora of degrees of freedom beyond the primordial curvature perturbation. The latter interacts in a…
Revisiting non-Gaussianity in multifield inflation with curved field space
Sebastian Garcia-Saenz, Lucas Pinol, Sébastien Renaux-Petel
Recent studies of inflation with multiple scalar fields have highlighted the importance of non-canonical kinetic terms in novel types of inflationary solutions. This motivates a th…
Hyper non-Gaussianities in inflation with strongly non-geodesic motion
Jacopo Fumagalli, Sebastian Garcia-Saenz, Lucas Pinol +2
Several recent proposals to embed inflation into high-energy physics rely on inflationary dynamics characterized by a strongly non-geodesic motion in negatively curved field space.…
