Addendum: Fitting the DESI BAO Data with Dark Energy Driven by the Cohen-Kaplan-Nelson Bound
Patrick Adolf, Martin Hirsch, Sara Krieg +2
Motivated by the recent Year-2 data release of the DESI collaboration, we update our results on time-varying dark energy models driven by the Cohen-Kaplan-Nelson bound. The previou…
Dark Energy Driven by the Cohen-Kaplan-Nelson Bound
Patrick Adolf, Martin Hirsch, Sara Krieg +2
In this work, we confront the bound on an ultraviolet cutoff (UV) of a quantum field theory (QFT) proposed by Cohen, Kaplan, and Nelson (CKN) with the latest results of the Dark En…
Neutrino Oscillations as a Gravitational Wave Detector?
Dominik Hellmann, Sara Krieg, Heinrich Päs +1
Gravitational waves (GWs) can alter the neutrino propagation distance and thus affect neutrino oscillations. This can result in a complete disappearance of the oscillatory behavior…
Fitting the DESI BAO Data with Dark Energy Driven by the Cohen-Kaplan-Nelson Bound
Patrick Adolf, Martin Hirsch, Sara Krieg +2
Gravity constrains the range of validity of quantum field theory. As has been pointed out by Cohen, Kaplan, and Nelson (CKN), such effects lead to interdependent ultraviolet (UV) a…
