Stabilizing dark matter with quantum scale symmetry
Abhishek Chikkaballi, Kamila Kowalska, Rafael R. Lino dos Santos +1
In the context of gauge-Yukawa theories with trans-Planckian asymptotic safety, quantum scale symmetry can prevent the appearance in the Lagrangian of couplings that would otherwis…

Crossing the desert: Towards predictions for SMEFT coefficients from quantum gravity
Lydia Brenner, Abhishek Chikkaballi, Astrid Eichhorn +1
The SMEFT provides a general framework to search for new physics beyond the current reach of direct detection. One such form of new physics is quantum gravity. Based on dimensional…

Naturally small neutrino mass with asymptotic safety and gravitational-wave signatures
Abhishek Chikkaballi, Kamila Kowalska, Enrico Maria Sessolo
We revisit the dynamical generation of an arbitrarily small neutrino Yukawa coupling in the Standard Model with trans-Planckian asymptotic safety and apply the same mechanism to th…
