Next-to-leading order corrections to deeply virtual production of pseudoscalar mesons
Physics Letters B, 2017 We complete the perturbative next-to-leading order corrections to the hard scattering amplitudes of deeply virtual meson leptoproduction processes at leading twist-two level by presenting the results for the production of flavor singlet pseudoscalar ...

Semileptonic decay of Ds+→π0ℓ+νℓ via neutral meson mixing
Physics Letters B, 2020 Based on the mechanism of neutral meson mixing, we predict the branching fraction of the semileptonic decay of Ds+→π0ℓ+νℓ (ℓ=e, μ) using recently measured branching fraction of Ds+→ηe+νe by BESIII experiment.

q‐Deformed Glueball Spectrum in AdS/QCD Correspondence
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.This work presents the application of the q‐algebra in the glueball spectrum. This algebra is implemented through Jackson’s derivatives in a Schrödinger‐like equation resulting from the gravity fluctuations around the braneworld scenario in five dimensions.

Exact formula of the spectrum of the pseudoscalar octet
Physics Letters B, 2015 Non-perturbative proof is presented of a generalized version of Goldstone theorem, where the Lagrangian conserves an approximate SU(3) chiral symmetry, that both quark masses and electromagnetism make contributions to the masses of spinless particles of ...

Pseudoscalar mesons in hot, dense matter [PDF]
Physical Review C, 2004 Phase transitions in hot and dense matter and the in--medium behavior of pseudoscalar mesons ($π^{\pm}, π^0, K^{\pm}, K^0 ,\bar K^0,η{and} η' $) are investigated, in the framework of the three flavor Nambu--Jona-Lasinio model, including the 't Hooft interaction, which breaks the $U_A(1)$ symmetry.

The light invisible boson in FCNC decays of B and $$B_c$$ B c mesons
European Physical Journal C: Particles and Fields, 2021 In this paper, we study the FCNC decay processes of B and $$B_c$$ B c meson, in which one invisible particle is emitted. Both the spin-0 and spin-1 cases are considered.

Meson–baryon coupling constants of the SU(3) baryons with flavor SU(3) symmetry breaking
Physics Letters B, 2018 We investigate the strong coupling constants for the baryon octet–octet, decuplet–octet, and decuplet–decuplet vertices with pseudoscalar mesons within a general framework of the chiral quark-soliton model, taking into account the effects of flavor SU(3)
