We have analyzed the $\gamma p\rightarrow p\pi^0\eta$ process with a particular focus on the role of a triangle singularity which appears in the decay of the $\Delta(1700)$ into $\eta\Delta(1232)$, where the $\Delta(1232)$ goes into $p$ emitting a $\

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

We report on the interaction of $D N$, $D^* N$, together with their coupled channels, by using an extension of the local hidden gauge formalism from the light meson sector, which is based on heavy quark spin symmetry. The scheme is based on the use o

We study the mechanism of triangular singularity of the $a_1(1260)$ decay to $\pi^+f_0(980)$ within the chiral unitary approach. Our results provide a natural explanation of all the features observed in the COMPASS experiment. Therefore the $a_1(1420

In this work, we have studied the $D_s^+$ decays into $\pi^+\pi^+\pi^-$ and $\pi^+K^+K^-$ mesons using the techniques from chiral unitary approach to account for the final state interactions in those processes. For this we have adopted a model in whi

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

In this talk, we investigate the molecular nature of the $D_{s0}^{*}(2317)^+$ resonance in the weak decay of the $B_c$ meson to $ J/\psi DK$. In this process, the heavy meson $B_c$ first decays into the quark pair $c\bar{s}$ via weak interaction and

In this work, we have studied the $\Lambda_b \rightarrow J/\psi K^{-} p$ decay via $\Lambda^*$-charmonium-proton intermediate states and discussed all possible triangle singularities. Using this process we have done a detailed analysis of the singula

We briefly discuss how the chiral unitary approach in coupled channels and $SU(3)$ symmetry can be used to describe the production of $f_0(500)$, $f_0(980)$ and $a_0(980)$ in the $\chi_{c1} \to \eta \pi^+ \pi^-$ reaction, recently measured by the BES

In this work we calculate the ratios of rates of the $\Xi_b$ nonleptonic and semileptonic decays into the $\Xi_c$(2790) and $\Xi_c$(2815) ($\Xi_c^*$) resonances. These resonances are dynamically generated from the pseudoscalar-baryon and vector-baryo
