The gravitational-wave physics [PDF]

open access: yesNational 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 ...

Gravitational Waves. Introduction to the Gravitational Wave Equation

open access: yes, 2023
Gravitational Waves represent the transport of Gravitational Energy through Space. Equation (103) represents the “Gravitational Wave Equation”. The article presents a new theory in physics which explains the interaction between gravity and light with mathematical results close to General Relativity (15 digits beyond the decimal point equal result) and

Detection of gravitational waves by light perturbation

open access: yesEuropean 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.

GRAVITATIONAL WAVES IN THE HYPERSPACE? [PDF]

open access: yesModern Physics Letters A, 2009
In the framework of the debate on high-frequency gravitational waves (GWs), after a review of GWs in standard General Relativity, which is due for completness, the possibility of merging such a traditional analysis with the hyperspace formalism that has been recently introduced in some papers in the literature, with the goal of a better understanding ...

QED factorization of two-body non-leptonic and semi-leptonic B to charm decays

open access: yesJournal of High Energy Physics, 2021
The QCD×QED factorization is studied for two-body non-leptonic and semi-leptonic B decays with heavy-light final states. These non-leptonic decays, like B ¯ s 0 → D s + π − $$ {\overline{B}}_{(s)}^0\to {D}_{(s)}^{+}{\pi}^{-} $$ and B ¯ d 0 → D + K − $$ {\

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

open access: yes, 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 ...

The velocity of gravitational waves [PDF]

open access: yesPhysics Letters A, 1999
We examine the propagation of gravitational waves in the new field theory of gravitation recently proposed by Novello-De Lorenci-Luciane (NDL). This examination is done on a solvable case corresponding to a spherically symmetric static configuration. We show that in NDL theory the velocity of gravitational waves is lower than light velocity.

QCD factorization of the four-lepton decay $$B^-\rightarrow \ell \bar{\nu }_\ell \ell ^{(\prime )} \bar{\ell }^{(\prime )}$$ B - → ℓ ν ¯ ℓ ℓ ( ′ ) ℓ ¯ ( ′ )

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Motivated by the first search for the rare charged-current B decay to four leptons, $$\ell \bar{\nu }_\ell \ell ^{(\prime )} \bar{\ell }^{(\prime )}$$ ℓ ν ¯ ℓ ℓ ( ′ ) ℓ ¯ ( ′ ) , we calculate the decay amplitude with factorization methods. We obtain the $
