Holographic mesons in D4/D6 model revisited
, 2011 We revisit holographic mesons in the D4/D6 model to study holographic light vector mesons and the properties of heavy quarkonium in confining and deconfining phases.

Dissociation of J/ψ and Y Using Dissociation Energy Criteria in N‐Dimensional Space
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.The analytical exact iteration method (AEIM) has been widely used to calculate N‐dimensional radial Schrodinger equation with medium‐modified form of Cornell potential and is generalized to the finite value of magnetic field (eB) with quasiparticle approach in hot quantum chromodynamics (QCD) medium.

Unquenching the Quark Model in a Nonperturbative Scheme
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 In recent years, the discovery in quarkonium spectrum of several states not predicted by the naive quark model has awakened a lot of interest. A possible description of such states requires the enlargement of the quark model by introducing quark‐antiquark pair creation or continuum coupling effects.

, 2017 In this addendum to Phys.\ Rev.\ D {\bf 95}, 054018 (2017) we recompute the rates for the decays of the Higgs boson to a vector quarkonium plus a photon, where the vector quarkonium is $J/\psi$, $\Upsilon(1S)$, $\Upsilon(2S)$, or $\Upsilon(3S)$.

Physics Letters B, 1977 Motivated by the apparent equal spacing M (ϒ′) - M (ϒ) = M ψi) - M (ψ), we show that the potential for which quarkonium level spacings are independent of quark mass, in the nonrelativistic limit, is V ( r ) = C In ( r / r 0 ). We enumerate consequences of the logarithmic potential and present an alternative interpretation of the data.

Radiative transitions and the quarkonium magnetic moment [PDF]
, 2006 I discuss heavy quarkonium radiative transitions and the related issue of the quarkonium magnetic moment inside effective field theories. Differences in set up and conclusions with respect to typical phenomenological approaches are outlined.Comment: 7 ...

Double Charmonium Productions in Electron‐Positron Annihilation Using Bethe‐Salpeter Approach
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 We calculate the double charmonium production cross‐section within the framework of 4 × 4 Bethe‐Salpeter Equation in the electron‐positron annihilation, at center of mass energy s=10.6GeV, that proceeds through the exchange of a single virtual photon.

Quarkonium correlators at finite temperature and potential models [PDF]
, 2007 We discuss the calculations of quarkonium spectral functions in potential models and their implications for the interpretation of the lattice data on quarkonium correlators. In particular, we find that melting of different quarkonium states does not lead
