Study of the Ground‐State Energies of Some Nuclei Using Hybrid Model
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 The quark‐quark (QQ) interaction as a perturbed term to the nucleon‐nucleon interaction (NN) without any coupling between them is studied in a hybrid model. This model is used to calculate the ground‐state energies of 2H1 and 4He2 nuclei. In a semirelativistic framework, this model is encouraged for light nuclei and the instanton‐induced interaction by

European Physical Journal C: Particles and Fields, 2018 We investigate the decays of $$\bar{B}^0_s$$ B¯s0 , $$\bar{B}^0$$ B¯0 and $$B^-$$ B- into $$\eta _c$$ ηc plus a scalar or vector meson in a theoretical framework by taking into account the dominant process for the weak decay of $$\bar{B}$$ B¯ meson into $

Radiative decays of vector and pseudoscalar nonets
EPJ Web of Conferences, 2012 Using a counting scheme which treats the light pseudoscalar and the light vector-meson nonet on equal footing, the decays of the narrow light vector mesons into a pseudoscalar meson and a dilepton and of the η′ meson into an ɷ meson and a dielectron are ...

Multipole analysis of spin observables in vector meson photoproduction [PDF]
, 1995 A multipole analysis of vector meson photoproduction is formulated as a generalization of the pseudoscalar meson case. Expansion of spin observables in the multipole basis and behavior of these observables near threshold and resonances are examined ...

The Ds0(2590)+ as the dressed cs¯(21S0) meson in a coupled-channels calculation
Physics Letters B, 2022 The recent discovery of the Ds0(2590)+ meson by the LHCb Collaboration has stimulated the analysis of meson-meson channels effects in the two-body quark-antiquark meson spectrum.

European Physical Journal C: Particles and Fields, 2023 We calculate the complete T matrices of the elastic light pseudoscalar meson and heavy meson scattering to the third order in heavy meson chiral perturbation theory. We determine the low-energy constants by fitting the phase shifts and scattering lengths

Decay of the pseudoscalar glueball into vector, axial-vector, scalar and pseudoscalar mesons
European Physical Journal C: Particles and Fields, 2023 We resume the investigation of the ground-state pseudoscalar glueball, $$J^{PC}=0^{-+}$$ J PC = 0 - + , by computing its two- and three-body decays into vector and axial-vector quark-antiquark meson fields additional to scalar and pseudoscalar mesons ...

Hidden gauge formalism for the radiative decays of axial-vector mesons [PDF]
, 2008 The radiative decay of the axial-vector resonances into a pseudoscalar meson and a photon is studied using the vector meson Lagrangian obtained from the hidden gauge symmetry (HGS) formalism.
