Wiggly dilaton: a landscape of spontaneously broken scale invariance
Sudhakantha Girmohanta, Yuichiro Nakai, Yu-Cheng Qiu +1
The dilaton emerges as a pseudo-Nambu-Goldstone boson (pNGB) associated with the spontaneous breaking of scale invariance in a nearly conformal field theory (CFT). We show the exis…
Cold Darkogenesis: Dark Matter and Baryon Asymmetry in Light of the PTA Signal
Kohei Fujikura, Sudhakantha Girmohanta, Yuichiro Nakai +1
We build upon the intriguing possibility that the recently reported nano-Hz gravitational wave signal by Pulsar Timing Array (PTA) experiments is sourced by a strong first-order ph…
How Viable Is a QCD Axion near 10 MeV?
Sudhakantha Girmohanta, Shota Nakagawa, Yuichiro Nakai +1
There has been an attempt to revive the visible QCD axion at the 10 MeV scale assuming that it exclusively couples to the first-generation quarks and the electron. This variant of…
Note on Warped Compactification -- Finite Brane Potentials and Non-Hermiticity --
Sudhakantha Girmohanta, Yuichiro Nakai, Motoo Suzuki +2
We study radius stabilization in the Randall-Sundrum model without assuming any unnaturally large stabilizing scalar potential parameter at the boundary branes () by the frequen…
