We study light scalar mesons in the holographic QCD soft-wall model with a background dilaton field. The masses and decay constants are compatible experiment determinations if ${a}_{0}(980)$ ${f}_{0}(980)$ identified as lightest mesons; moreover, states organized linear Regge trajectories same slope of vector mesons. Comparing two-point correlation function operators derived on anti--de Sitter side QCD, information about condensates can be derived. Strong couplings to pairs pseudoscalar turn...
We investigate the spectra of light scalar and vector glueballs in a holografic description QCD with dilaton background bulk field. In particular, we study how glueball masses depend on conditions geometry bulk.
All the available experimental information on open charm and beauty mesons is used to classify observed states in heavy quark doublets. The masses of some still unobserved are predicted, particular sector. Adopting an effective Lagrangian approach based chiral symmetry, individual decay rates ratios branching fractions computed, with results useful assign quantum numbers recently charmed which need be properly classified. Implications predictions for corresponding provided. already copious,...
We use gauge/string duality to investigate the free energy of two static color sources (a heavy-quark--antiquark pair) in a Yang-Mills theory strongly interacting matter, varying temperature and chemical potential. The dual space geometry is anti--de Sitter with charged black hole describe finite density boundary theory, we also include background warp factor generate confinement. resulting deconfinement line $\ensuremath{\mu}\ensuremath{-}T$ plane similar one obtained by lattice effective...
We study scalar glueballs and mesons at $T \neq 0$ in the soft wall holographic QCD model. find that, using Anti-de Sitter-Black Hole metric for all values of temperature, masses hadronic states decrease widths become broader when T increases, there are temperatures which disappear from glueball meson spectral functions. However, correspondence such phenomena occur low, order 40-60 MeV. A consistent description in-medium effects on hadron properties should include Hawking-Page transition,...
We compute the light axial-vector and tensor meson two-photon transition form factors in soft-wall holographic model of quantum chromodynamics (QCD) flavor-symmetric case. They are used to evaluate contributions anomalous magnetic moment muon via hadronic light-by-light scattering process. As expected, these smaller than one from pseudoscalar mesons. The result for mesons is higher value found other approaches. Published by American Physical Society 2024
We study how to assign the recently observed ${D}_{sJ}(2700)$ meson an appropriate level of $c\overline{s}$ spectrum by analysis its decay modes in final states comprising a light pseudoscalar meson. use effective Lagrangian approach with heavy quark and chiral symmetries, obtaining that measurement ${D}^{*}K$ width would allow one distinguish between two possible assignments.
We study the chiral condensate at finite temperature in AdS/QCD a time-dependent background, which position of black-hole horizon $z_h$ changes with time, producing an increasing or decreasing temperature. Conformal invariance is broken, as soft-wall model, by static quadratic dilaton. Two different scenarios are analysed: first general power-law time dependence assumed for $z_h$, while second energy-momentum tensor late times reproduces one found viscous hydrodynamics. Depending on rate...
We consider the vertex function of two vector and one axial-vector currents using soft-wall holographic model QCD with Chern-Simons term. Two structure functions ${w}_{L}$ ${w}_{T}$ describe such a in special case which corresponds to an on-shell soft photon. briefly review results for these functions, obtained from triangular loop diagrams quarks having mass ${m}_{q}=0$ or ${m}_{q}\ensuremath{\ne}0$, we compute compare outcome findings. also calculate discuss two-point...
The lowest dimensional gluon condensate ${G}_{2}$ is analyzed at finite temperature and chemical potential using a holographic model of QCD with conformal invariance broken by background dilaton. Starting from the free energy model, thermodynamical quantities needed to determine $T$ $\ensuremath{\mu}$ dependence are evaluated. At high independent potential. Moreover, $\ensuremath{\mu}=0$, temporal spatial Wilson loops low computed; they related (chromo)electric magnetic components ${G}_{2}$,...

It has been suggested that the radiative $X \to D \bar γ$ decay modes are useful to shed light on structure of meson X(3872), since ratio $ R={Γ(X D^+ D^- γ) \over Γ(X D^0 γ)}$ is expected be small ($R \ll 1$) if $X$ a molecular $D^{*0} D^0$ state. We compute $R$ in $\bar c c$ $J^{PC}=1^{++}$ description finding it tiny wide range hadronic parameters governing decay. A discrimination between and can obtained through analysis photon spectrum.
