Standard Model predictions for lepton flavour universality ratios of inclusive semileptonic B decays

Journal of High Energy Physics, 2022
We present Standard Model predictions for lepton flavour universality ratios of inclusive B → X(c) ℓ ν ¯ ℓ $$ \ell {\overline{\nu}}_{\ell } $$ . For the ℓ = μ, e, these ratios are very close to unity as expected.

The gravitational-wave physics [PDF]

National Science Review, 2017
Abstract The direct detection of gravitational wave by Laser Interferometer Gravitational-Wave Observatory indicates the coming of the era of gravitational-wave astronomy and gravitational-wave cosmology. It is expected that more and more gravitational-wave events will be detected by currently existing and planned gravitational-wave ...

Relative attitude stability analysis of double satellite formation for gravity field exploration in space debris environment

Scientific Reports, 2023
Spacecraft operating in low orbit are at risk of being hit by space debris. In the debris environment, the impact of debris is likely to cause the double satellite formation to exit science mode or even lead to the divergence of the control system, thus ...

Multiple imaging by gravitational waves [PDF]

, 1997
Gravitational waves act like lenses for the light propagating through them. This phenomenon is described using the vector formalism employed for ordinary gravitational lenses, which was proved to be applicable also to a non-stationary spacetime, with the

Detection of gravitational waves by light perturbation

European Physical Journal C: Particles and Fields, 2021
Light undergoes perturbation as gravitational waves pass by. This is shown by solving Maxwell’s equations in a spacetime with gravitational waves; a solution exhibits a perturbation due to gravitational waves.

Propagation of gravitational waves in the nonperturbative spinor vacuum [PDF]

, 2014
The propagation of gravitational waves on the background of a nonperturbative vacuum of a spinor field is considered. It is shown that there are several distinctive features in comparison with the propagation of plane gravitational waves through empty ...
