Detecting Axion-Like Particles With Coiled Optical Fibers I: Silica Fibers
Gia Dvali, Sebastian Zell, Tongxuan Zhang
We propose a new approach to axion-like particle (ALP) searches based on long, coiled optical fibers in an external magnetic field. We develop the theoretical framework required to…
Weyl-invariant Einstein-Cartan gravity: unifying the strong CP and hierarchy puzzles
Georgios K. Karananas, Mikhail Shaposhnikov, Sebastian Zell
We show that the minimal Weyl-invariant Einstein-Cartan gravity in combination with the Standard Model of particle physics contains just one extra scalar degree of freedom (in addi…
Consistent particle physics in metric-affine gravity from extended projective symmetry
Will Barker, Sebastian Zell
It is well-known that the Einstein-Hilbert action exhibits a projective invariance in metric-affine gravity, generated by a single vector (just like diffeomorphisms). However, this…
Scale invariant Einstein-Cartan gravity and flat space conformal symmetry
Georgios K. Karananas, Mikhail Shaposhnikov, Sebastian Zell
We find the conditions under which scale-invariant Einstein-Cartan gravity with scalar matter fields leads to an approximate conformal invariance of the flat space particle theory…
Critical Points in Palatini Higgs Inflation with Small Non-Minimal Coupling
Arthur Poisson, Inar Timiryasov, Sebastian Zell
We investigate inflation driven by the Higgs boson in the Palatini formulation of General Relativity. Our analysis primarily focuses on a small non-minimal coupling of the Higgs fi…
