Asymptotic safety meets tensor field theory: towards a new class of gravity-matter systems
Astrid Eichhorn, Razvan Gurau, Zois Gyftopoulos
Combining asymptotically safe quantum gravity with a tensor field theory, we exhibit the first example of a theory with gravity and scalar fields in four dimensions which may reali…
From quantum gravity to gravitational waves through cosmic strings
Astrid Eichhorn, Rafael R. Lino dos Santos, João Lucas Miqueleto
New physics beyond the Standard Model can give rise to stochastic gravitational-wave backgrounds, for example through cosmic strings. In this way, gravitational-wave searches with…
Towards a bound on the Higgs mass in causal set quantum gravity
Gustavo P. de Brito, Astrid Eichhorn, Ludivine Fausten
In the Standard Model of particle physics, the mass of the Higgs particle can be linked to the scale at which the Standard Model breaks down due to a Landau pole/triviality problem…
Suppression of proton decay in quantum gravity
Astrid Eichhorn, Shouryya Ray
The bound on the proton lifetime is one of a small handful of observations that constrains physics not far from the Planck scale. This calls for a calculation of the proton lifetim…
Higher-order curvature operators in causal set quantum gravity
Gustavo. P. de Brito, Astrid Eichhorn, Christopher Pfeiffer
We construct higher-order curvature invariants in causal set quantum gravity. The motivation for this work is twofold: first, to characterize causal sets, discrete operators that e…
Black holes in asymptotically safe gravity and beyond
Astrid Eichhorn, Aaron Held
Asymptotically safe quantum gravity is an approach to quantum gravity that achieves formulates a standard quantum field theory for the metric. Therefore, even the deep quantum grav…
