Light Dilaton in Rare Meson Decays and Extraction of its CP Property
Sudhakantha Girmohanta, Yuichiro Nakai, Yoshihiro Shigekami +1
The dilaton is a pseudo-Nambu-Goldstone boson associated with the spontaneous breaking of scale invariance in a nearly conformal theory, and couples to the trace of the stress-…
Aiming for Tops of ALPs with a Muon Collider
So Chigusa, Sudhakantha Girmohanta, Yuichiro Nakai +1
Future muon colliders with center-of-mass energy of TeV can provide a clean high-energy environment with advantages in searches for TeV-scale axion-like particl…
NANOGrav Signal from a Dark Conformal Phase Transition
Kohei Fujikura, Sudhakantha Girmohanta, Yuichiro Nakai +1
We explore the possibility that a confining first-order phase transition of a nearly-conformal dark sector generates the reported NANOGrav signal of a stochastic gravitational wave…
Multi-brane cosmology
Sudhakantha Girmohanta, Seung J. Lee, Yuichiro Nakai +1
5D warped extra dimension models with multiple 3-branes can naturally realize multiple hierarchical mass scales which are ubiquitous in physics beyond the Standard Model. We discus…
Model of the quintessence axion
Sudhakantha Girmohanta, Yu-Cheng Qiu, Jin-Wei Wang +1
We construct a model of the quintessence axion based on a gauged chiral symmetry and an additional flat fifth dimension. The required high qualities are guaranteed by the br…
