We study the$$D^+ \rightarrow \pi ^+ \eta \eta $$D+→π+ηηand$$D^+ \rightarrow \pi ^+ \pi ^0 \eta $$D+→π+π0ηreactions, which are single Cabibbo suppressed and can proceed both through internal and external emission. The primary mechanisms at

We study the e + e − → K + ( D s ⁎ − D 0 + D s − D ⁎ 0 ) reaction recently measured at BESIII, from where a new Z c s state has been reported. We study the interaction of D ¯ s D ⁎ with the coupled channels J / ψ K − , K ⁎ − η

First we study the $B^0$ decay to $D^0 \bar D^0 K^0$ and make predictions for the $D^0 \bar D^0$ invariant mass distribution within the chiral unitary approach in which the X(3720) resonance are dynamically generated. From the shape of the distributi

We report on the decay of the $f_1(1285)$ into $\pi a_0(980)$ and $K^* \bar K$. We find a shoulder around 1400 MeV, tied to a triangle singularity, for the $\pi a_0(980)$ decay mode, and a peak around 1420 MeV for the $K^* \bar K$ mode. Both these fe

The BES data on the $J/\psi \to \eta K^{*0} \bar{K}^{*0}$ reaction show a clear enhancement in the $K^{*0} \bar{K}^{*0}$ mass distribution close to the threshold of this channel. Such an enhancement is usually a signature of a resonance around thresh

In this talk I present a series of theoretical works regarding the $\Lambda_b \to J/\psi K^- p$ reaction from where a recent experiment by the LHCb collaboration at CERN claimed the existence of two hidden charm pentaquarks, $P_c(4380)^+$ and $P_c(44

We have studied the $J/\ensuremath{\psi}\ensuremath{\phi}$ mass distribution of the ${B}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi}{K}^{+}$ reaction from threshold to about 4250 MeV, and find that one needs the contribution of th

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

The D 0 decay into K s 0 and a scalar resonance, f 0 ( 500 ) , f 0 ( 980 ) , a 0 ( 980 ) , are studied obtaining the scalar resonances from final state interaction of a pair of mesons produced in a first step in the D 0 decay into K s 0 and the pair

Nonleptonic weak decays of ${\mathrm{\ensuremath{\Xi}}}_{c}$ into ${\ensuremath{\pi}}^{+}$ and a meson $(M)$-baryon $(B)$ final state, $MB$, are analyzed from the viewpoint of probing $S=\ensuremath{-}2$ baryon resonances, i.e., $\mathrm{\ensuremath{
