Universal gravitational-wave signatures from heavy new physics in the electroweak sector
Astrid Eichhorn, Johannes Lumma, Jan M. Pawlowski +2
We calculate the gravitational-wave spectra produced by the electroweak phase transition with TeV-scale Beyond-Standard-Model physics in the early universe. Our study captures the…
Gravitational instantons and anomalous chiral symmetry breaking
Yu Hamada, Jan M. Pawlowski, Masatoshi Yamada
We study anomalous chiral symmetry breaking in two-flavour QCD induced by gravitational and QCD-instantons within asymptotically safe gravity within the functional renormalisation…
Gauge hierarchy problem and scalegenesis
Masatoshi Yamada
We review the gauge hierarchy problem in the standard model. We discuss the meaning of the quadratic divergence in terms of the Wilsonian renormalization group. Classical scale sym…
Dynamically emergent gravity from hidden local Lorentz symmetry
Shinya Matsuzaki, Shota Miyawaki, Kin-ya Oda +1
Gravity can be regarded as a consequence of local Lorentz (LL) symmetry, which is essential in defining a spinor field in curved spacetime. The gravitational action may admit a zer…
Scalegenesis and fermionic dark matters in the flatland scenario
Yu Hamada, Koji Tsumura, Masatoshi Yamada
We propose an extension of the standard model with Majorana-type fermionic dark matters based on the flatland scenario where all scalar coupling constants, including scalar mass te…
