Extremal curves of Perlick's proper time in Weyl geometry
E. Rodrigues, F. Dahia, I. P. Lobo +1
We investigate the extremization of Perlick's proper time in non-integrable Weyl geometry. We derive the corresponding generalized Euler--Lagrange equations and show that the resul…
Probing Short-Distance Modifications of Gravity via Spin-Independent and Spin-Dependent Effects in Muonic Atoms
J. E. J. Matias, A. S. Lemos, F. Dahia
High-precision spectroscopy of muonic atoms provides a powerful probe for new short-range interactions predicted by theories beyond the Standard Model (SM). In this work, we derive…
Constraints on extra dimensions theories from gravitational quantum barrier experiments
J. M. Rocha, F. Dahia
We discuss the quantum-bouncer experiment involving ultracold neutrons in a braneworld scenario. Extra-dimensional theories typically predict the strengthening of gravitational int…
The alpha particle charge radius, the radion and the proton radius puzzle
F. Dahia, A. S. Lemos
Recent measurements of the Lamb shift of muonic helium-4 ions were used to infer the alpha particle charge radius. The value found is compatible with the radius extracted from the…
Neutron interferometry and tests of short-range modifications of gravity
J. M. Rocha, F. Dahia
We consider tests of short-distance modifications of gravity based on neutron interferometry in the scenario of large extra dimensions. Avoiding the non-computability problem in th…
An Invariant Approach to Weyl's unified field theory
T. A. T. Sanomiya, I. P. Lobo, J. B. Formiga +2
We revisit Weyl's unified field theory, which arose in 1918, shortly after general relativity was discovered. As is well known, in order to extend the program of geometrization of…
