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…

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…
