This paper outlines the roadmap towards the redefinition of the second, which was recently updated by the CCTF Task Force created by the CCTF in 2020. The main achievements and the open challenges related to the status of the optical frequency standa

Any variation of the fundamental physical constants, and more particularly of the fine structure constant, $\alpha$, or of the mass of the electron, $m_e$, would affect the recombination history of the Universe and cause an imprint on the cosmic micr

Radiative corrections to scalar masses in de Sitter space

Autor: Brunier, T., Bernardeau, F., Uzan, J. -P.

Publikováno v: Phys.Rev. D71 (2005) 063529

We compute the radiative corrections to the mass of a test boson field in an inflating space-time. The calculations are carried out in case of a boson part of a supersymmetric chiral multiplet. We show that its mass is preserved up to logarithmic div

Localisation of massive fermions on the brane

Autor: Ringeval, C., Peter, P., Uzan, J. -P.

Publikováno v: Phys.Rev. D65 (2002) 044016

We construct an explicit model to describe fermions confined on a four dimensional brane embedded in a five dimensional anti-de Sitter spacetime. We extend previous works to accommodate massive bound states on the brane and exhibit the transverse str
