We propose a holographic model that unifies the description of masses and decay constants, leading to a precise match with experimental data on heavy quarkonia. Finite temperature effects are considered by calculating the current-current spectral functions of heavy vector mesons. The identification of quasiparticle states as Breit-Wigner resonances in the holographic spectral function was made. We develop a prescription to subtract background contributions from the spectral function to isolate the Breit-Wigner peak. The quasi-particle holographic thermal evolution is described, allowing us to estimate the melting temperature for vector charmonia and bottomonia. Our holographic model predicts that 𝐽/Ψ melts at 415 MeV ( ∼2.92⁢𝑇𝑐) and ϒ melts at 465 MeV ( ∼3.27⁢𝑇𝑐).enacceso abiertoAstronomy And AstrophysicsPhysics, Particles And Fieldsarticle
