In view of the proliferation in the number of new charmonium states, it is really important to have an experimental way to prove that an observed bump is, indeed, a real resonance. To do that, in this paper we present an alternative method to demonst

We study the B¯s0→Ds−(KD)+ weak decay, and look at the KD invariant mass distribution, for which we use recent lattice QCD results for the KD interaction from where the Ds0⁎(2317) resonance appears as a KD bound state. Since there are not yet

Supersymmetric Light Front Holographic QCD is a holographic theory, which not only describes the spectroscopy of mesons and baryons, but also predicts the existence and spectroscopy of tetraquarks. A discussion of the limitations of the theory is als

In this work we study the interactions of bottom mesons which lead to $\Upsilon$ production and absorption in hot hadronic matter. We use effective Lagrangians to calculate the $\Upsilon$ production cross section in processes such as $ \bar{B}^{(*)}

Motivated by the experimental findings of some new exotic states decaying into channels like $J/\psi \phi$, we investigate the formation of resonances/bound states in the $D^*_s\bar D^*_s$ system using QCD sum rules. To do this we start with a curren

To understand the nature of the X ( 5568 ) , recently observed in the mass spectrum of the B s 0 π ± system by the D0 Collaboration, we have investigated, in a previous work, a scalar tetraquark (diquak–antidiquark) structure for it, within the t

In this work we investigate the $$Z_b (10610)$$ (called simply $$Z_b$$ ) abundance in the hot hadron gas produced in heavy ion collisions after the quark–gluon plasma phase. We use effective Lagrangians to calculate the thermally averaged cross sec

Relativistic light-front bound-state equations for double-heavy mesons, baryons and tetraquarks are constructed in the framework of supersymmetric light front holographic QCD. Although heavy quark masses strongly break conformal symmetry, supersymmet
