Scheme dependence of quantum gravity on de Sitter background
Hiroyuki Kitamoto, Yoshihisa Kitazawa
We extend our investigation of the IR effects on the local dynamics of matter fields in quantum gravity. Specifically we clarify how the IR effects depend on the change of the quan…

Soft Graviton effects on Gauge theories in de Sitter Space
Hiroyuki Kitamoto, Yoshihisa Kitazawa
We extend our investigation of soft graviton effects on the microscopic dynamics of matter fields in de Sitter space. We evaluate the quantum equation of motion in generic gauge th…

Soft Gravitons Screen Couplings in de Sitter Space
Hiroyuki Kitamoto, Yoshihisa Kitazawa
The scale invariance of the quantum fluctuations in de Sitter space leads to the appearance of de Sitter symmetry breaking infra-red logarithms in the graviton propagator. We inves…
