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…
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…
Is the proton radius puzzle evidence of extra dimensions?
F. Dahia, A. S. Lemos
The proton charge radius inferred from muonic hydrogen spectroscopy is not compatible with the previous value given by CODATA-2010, which, on its turn, essentially relies on measur…
Constraints on extra dimensions from atomic spectroscopy
F. Dahia, A. S. Lemos
We consider a hydrogen atom confined in a thick brane embedded in a higher-dimensional space. Due to effects of the extra dimensions, the gravitational potential is amplified in di…
