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.

Investigation of meson-meson interaction [PDF]

, 2021
In the framework of the quark delocalization color screening model, we investigate the meson-meson interaction in the fully light four-quark system . The calculation of the effective potentials of all the $S-$wave states shows that for most states the ...

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.

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.

Non-leptonic B-decays in and beyond QCD factorisation [PDF]

, 2005
This thesis examines the non-leptonic B-decays within QCD factorization and beyond, to challenge the assumptions and limitations of the method. We analyse the treatment of the distribution amplitudes of light mesons and present a new model described by ...

Complete sets of observables in pseudoscalar-meson photo-production [PDF]

, 2014
Pseudoscalar-meson photoproduction is characterized by four complex reaction amplitudes. A complete set is a minimum theoretical set of observables that allow to determine these amplitudes unambiguously.

The pseudoscalar meson electromagnetic form factor at high Q2 from full lattice QCD [PDF]

, 2017
We give an accurate determination of the vector (electromagnetic) form factor, F(Q^2), for a light pseudoscalar meson up to squared momentum transfer Q^2 values of 6 GeV^2 for the first time from full lattice QCD, including u, d, s and c quarks in the ...

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)
