We used the diffusion Monte Carlo method to solve the Schrodinger equation describing several tetraquark
systems within the quark model framework.
We applied this technique both to all-heavy and to groupings with a couple of light quarks, in particular, to the
structure of X(3872).
Our approach produced a meson-meson configuration for that arrangement but,
contrarily to the usual $D^0\bar{D}^

Based on the constraints of the heavy quark spin symmetry, we investigate the $P_{cs}(4459)$ state using a coupled channel approach. Before the experimental findings, we had made some predictions. Using the experimental results, one can determine the free parameters. We dynamically reproduce the $P_{cs}(4459)$ state in the coupled channel interactions, which may be a degenerate state. Furthermore,

I discuss a novel scenario for the pentaquark-like signals in the LHCb data. I identify double triangle mechanisms with kinematical singularities. I demonstrate that the double triangle amplitudes reproduce the peak structures of $P_c(4312)$, $P_c(4380)$, and $P_c(4457)$, through an interference with other common mechanisms. Only the $P_c(4440)$ peak is due to a resonance with width and strength

The Belle II experiment has accumulated data corresponding to 89.99 fb-1 integrated luminosity in the past 2 years, and is performing very well. We present here the analysis of B -> K J/psi pi pi and B -> K psi(2S): in the former for the first time the evidence for the X(3872) --->Jpsi pi pi has been found at Belle II, which is consistent with the observation at Belle of the same resonant state.

If the X(3872) is a weakly bound charm-meson molecule, it can be produced by the creation of $D^* \bar D^*$ at short distances followed by the rescattering of the charm mesons into X(3872) and a photon or a pion through a triangle loop. A triangle singularity produces narrow peak in the reaction rate in production of X(3872). The observation of this peak would provide strong evidence in support of
