Dark matter in scale-invariant gravity with hidden-sector condensation
Juan P. Garcés, Jisuke Kubo, Manfred Lindner +1
The origin of the electroweak scale, cosmic inflation, and dark matter are often treated as independent problems beyond the Standard Models of particle physics and cosmology. In th…
Gravity and the Hierarchy Problem
Thede de Boer, Jisuke Kubo, Manfred Lindner +1
We propose a mechanism where the dynamical generation of the Planck mass in scale invariant gravity leads to Einstein gravity, successful inflation and an explanation of the hierar…
Scale Invariant Extension of the Standard Model: A Nightmare Scenario in Cosmology
Mayumi Aoki, Jisuke Kubo, Jinbo Yang
Inflationary observables of a classically scale invariant model, in which the origin of the Planck mass and the electroweak scale including the right-handed neutrino mass is chiral…
Unitarity Violation in Field Theories of Lee-Wick's Complex Ghost
Jisuke Kubo, Taichiro Kugo
Theories with fourth-order derivatives, including the Lee-Wick finite QED model and Quadratic Gravity, have a better UV behaviour, but the presence of negative metric ghost modes e…
Spontaneous Conformal Symmetry Breaking and Quantum Quadratic Gravity
Jisuke Kubo, Jeffrey Kuntz
We investigate several quantum phenomena related to quadratic gravity after rewriting the general fourth-order action in a more convenient form that is second-order in derivatives…
Inflation with Massive Spin-2 Ghosts
Jisuke Kubo, Jeffrey Kuntz, Jonas Rezacek +1
We consider a generic model of quadratic gravity coupled to a single scalar and investigate the effects of gravitational degrees of freedom on inflationary parameters. We find that…
