$f (R)$ gravity with broken Weyl gauge symmetry, cosmological backreaction, and its effects on CMB anisotropy

Jiwon Park, Tae Hoon Lee

We propose a new class of $f (R)$ theory where its Weyl gauge symmetry is broken in the primordial era of the universe. This symmetry forces one to adopt a new scalar field, namely…

An exact solution of the higher-order gravity in standard radiation-dominated era

Chae-min Yun, Jubin Park, Myung-Ki Cheoun +1

We report that the standard evolution of radiation-dominated era (RDE) universe $a \propto t^{1/2}$ is a sufficient condition for solving a sixth order gravitational field equation…
