Effective Lagrangian for Nambu-Goldstone modes in nonequilibrium open systems
Masaru Hongo, Suro Kim, Toshifumi Noumi +1
We develop the effective field theory of diffusive Nambu-Goldstone (NG) modes associated with spontaneous internal symmetry breaking taking place in nonequilibrium open systems. Th…

Heavy Spinning Particles from Signs of Primordial Non-Gaussianities: Beyond the Positivity Bounds
Suro Kim, Toshifumi Noumi, Keito Takeuchi +1
Within the so-called cosmological collider program, imprints of new particles on primordial non-Gaussianities have been studied intensively. In particular, their non-analytic featu…

Dressed Power-law Inflation with Cuscuton
Asuka Ito, Aya Iyonaga, Suro Kim +1
We study dressed inflation with a cuscuton and find a novel exact power-law solution. It is well known that the conventional power-law inflation is inconsistent with the Planck dat…
