Some like it hot: heals Higgs inflation, but does not cool it
Fedor Bezrukov, Dmitry Gorbunov, Chris Shepherd +1
Strong coupling in Higgs inflation at high energies hinders a joint description of inflation, reheating and low-energy dynamics. The situation may be improved with a proper UV comp…
Scalaron the healer: removing the strong-coupling in the Higgs- and Higgs-dilaton inflations
Dmitry Gorbunov, Anna Tokareva
We show that introducing -term makes the Higgs-inflation and Higgs-dilaton inflation consistent models: the strong coupling energy scales in scalar, gauge and gravity sectors…
On the dark radiation problem in the axiverse
Dmitry Gorbunov, Anna Tokareva
String scenarios generically predict that we live in a so called axiverse: the Universe with about a hundred of light axion species which are decoupled from the Standard Model part…
Polarization of photons emitted by decaying dark matter
W. Bonivento, D. Gorbunov, M. Shaposhnikov +1
Radiatively decaying dark matter may be searched through investigating the photon spectrum of galaxies and galaxy clusters. We explore whether the properties of dark matter can be…
