The X(3872) was discovered in 2003 by the Belle collaboration, and was subsequently confirmed by the CDF, D0, Babar and LHCb collaborations. This hadron lies within the mass range of the well-established charmonium mesons, but it is difficult to interpret as a charmonium state. In addition to the X(3872), several other hadrons have been discovered that are difficult to interpret as charmonium...

AdS/QCD is successful in predicting the diffractive $\rho$-meson production. It is then natural to investigate the prediction of this model for $B\to\rho$ transition form factors. This talk describes the derivation of the three form factors relevant for the semileptonic $B\to\rho\ell\nu$ decay along with the tensor form factor which enters $B\to\rho\gamma$ transition within light cone sum...

We use QCD light-cone sum rules with holographic anti de Sit- ter/Chromodynamics (AdS/QCD) Distribution Amplitudes (DAs) for the K∗ meson in order to predict the full set of seven B → K∗ transition form factors for intermediate-to-high recoil of the vector meson. We use our form factors to predict the differential and total branching fraction of the rare dileptonic decay B → K∗μ+μ− which we...

The original Gell-Mann–Okubo (GMO) formalism treats the light baryons as objects to be seen in light of the broken SU(3) symmetries of the three light quarks, and lead to the development of the famous Eightfold Way diagrams. In particular, each baryon mass group (N, $\Delta$, $\Sigma$, $\Sigma^*$, $\Xi$, $\Xi^*$, $\Omega$) form isospin multiplets who differ in strangeness values. With the...
