Cosmological Landsberg Finsler spacetimes
Annamária Friedl-Szász, Elena Popovici-Popescu, Nicoleta Voicu +2
We locally classify all possible cosmological homogeneous and isotropic Landsberg-type Finsler structures, in 4-dimensions. Among them, we identify viable non-stationary Finsler sp…
Experimental Bounds on Deformed Muon Lifetime Dilation
Iarley P. Lobo, Christian Pfeifer, Pedro H. Morais
We analyze Planck scale induced modifications of the relativistic time dilation using data from the Muon Storage Ring experiment at CERN. By examining the lifetimes of muons, we es…
Weak equivalence principle and nonrelativistic limit of general dispersion relations
Manuel Hohmann, Christian Pfeifer, Fabian Wagner
We study the weak equivalence principle in the context of modified dispersion relations, a prevalent approach to quantum gravity phenomenology. We find that generic modified disper…
Deflection of light rays in a moving medium around a spherically symmetric gravitating object
Barbora Bezděková, Oleg Yu. Tsupko, Christian Pfeifer
In most analytical studies of light ray propagation in curved spacetimes around a gravitating object surrounded by a medium, it is assumed that the medium is a cold nonmagnetized p…
