We study for the first time the pΣ→ Kd and Kd→ pΣ reactions close to threshold and show that they are driven by a triangle mechanism, with the Λ(1405) , a proton and a neutron as intermediate states, which develops a triangle singularity close

We perform a theoretical study of the Ds+→π+π+π-η decay. We look first at the basic Ds+ decay at the quark level from external and internal emission. Then we hadronize a pair or two pairs of qq¯ states to have mesons at the end. Posteriorly th

We present a mechanism for ωc→π+ω(2012) production through an external emission Cabibbo favored weak decay mode, where the ω(2012) is dynamically generated from the interaction of K̄Ξ∗(1530) and ηω, with K̄Ξ as the main decay channel. T

We propose two reactions, B¯0→K0D+K- and B¯0→K∗0D∗+K-, which have been already measured at Belle, to look into the JP=0+, X0(2866) state and a 1+ partner of molecular D∗K̄∗ nature by looking at the D+K- and D∗+K- invariant mass distr

We have identified the decay modes of the Ds+→π+K∗+K∗-,π+K∗0K¯∗0 reactions producing a pion and two vector mesons. The posterior vector–vector interaction generates two resonances that we associate to the f(1710) and the a(1710) recent

We study the Ds∗D¯∗ system in connection with the J/ψK∗ in coupled channels and observe that, within reasonable values of the cutoff used to regularize the loops, the system does not develop a bound state. However, the JP=2+ channel has enoug

We extend the theoretical framework used to describe the Tcc state as a molecular state of D∗D and make predictions for the D∗D∗ and Ds∗D∗ systems, finding that they lead to bound states only in the JP=1+ channel. Using input needed to desc

We perform a unitary coupled channel study of the interaction of the D*+D0,D*0D+ channels and find a state barely bound, very close to isospin I=0. We take the experimental mass as input and obtain the width of the state and the D0D0π+ mass distribu

We study theoretically the resonant structure of the double Cabibbo suppressed D+→K-K+K+ decay. We start from an elementary production diagram, considered subleading in previous approaches, which cannot produce a final K-K+ pair at the tree level b

By looking at the pseudoscalar-vector meson spectra in the B¯→J/ψρK̄ and B¯→J/ψK̄∗π weak decays, we theoretically investigate the double-pole structure of the K1(1270) resonance by using the chiral unitary approach to account for the fi
