We study for the first time the pΣ− → K−d and its time reversal reaction 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 sing

We have studied the exotic doubly charmed D*D system providing a natural explanation for the peak recently observed by LHCb, in terms of D*+D0 and D*0D+ with isospin I = 0. The width has been evaluated accurately based on the decay widths of the D* s

Assuming that the f 2 (1270), f ′2 (1525), a 2 (1320), and K * 2 (1430) resonances are dynamically generated states from the vector meson-vector meson interactions in L = 0 and spin 2, we study the γp → f 2 (1270)[f ′2 (1525)]p , γp → a 0 2

We present results extracting the position of the two Λ(1405) poles from experimental photoproduction data measured recently at different energies in the γp → K + π 0 Σ 0 and γp → K + π ± Σ ∓ reactions at Jefferson Lab. The analysis is

I make a short review of the situation of the kaonic systems, with novel information supporting the two Λ(1405) states from the K-d → nπΣ reaction. A review is made of the K¯$ar K$NN system with recent calculations converging to smaller binding

Predictions for hidden charm molecules, with and without strangeness, were made prior to the LHCb experiment. We discuss these issues and how these states can be observed in the reactions, Λ b → J / ψK − p , Λ b → J / ψη Λ, Λ b → J /
