Time-Sliced Perturbation Theory for Large Scale Structure I: General Formalism
Diego Blas, Mathias Garny, Mikhail M. Ivanov +1
We present a new analytic approach to describe large scale structure formation in the mildly non-linear regime. The central object of the method is the time-dependent probability d…
Renormalization of Horava Gravity
Andrei O. Barvinsky, Diego Blas, Mario Herrero-Valea +2
We prove perturbative renormalizability of projectable Horava gravity. The key element of the argument is the choice of a gauge which ensures the correct anisotropic scaling of the…
Experimental assessment of the speed of light perturbation in free-fall absolute gravimeters
H. Baumann, F. Pythoud, D. Blas +3
Precision absolute gravity measurements are growing in importance, especially in the context of the new definition of the kilogram. For the case of free-fall absolute gravimeters w…
Emergent Lorentz invariance with chiral fermions
Ivan Kharuk, Sergey Sibiryakov
We study renormalization group flows in strongly interacting field theories with fermions that correspond to transitions between a theory without Lorentz invariance at high energie…
Semiclassical S-matrix for black holes
Fedor Bezrukov, Dmitry Levkov, Sergey Sibiryakov
We propose a semiclassical method to calculate S-matrix elements for two-stage gravitational transitions involving matter collapse into a black hole and evaporation of the latter.…
On stability of electroweak vacuum during inflation
Andrey Shkerin, Sergey Sibiryakov
We study Coleman-De Luccia tunneling of the Standard Model Higgs field during inflation in the case when the electroweak vacuum is metastable. We verify that the tunneling rate is…
