“…Indeed, there is growing evidence that some existing and new observed hadronic states could be interpreted in terms of resonances or bound states of three hadrons [17][18][19]. Furthermore, some new states are also predicted in three-body systems [20][21][22].…”

The three-body ηK * K * , πK * K * and KK * K * systems are investigated within the framework of fixedcenter approximation to the Faddeev equations, where K * K * is treated as the scalar meson f0(1710). The interactions between π, η, K and K * are taking from the chiral unitary approach. By scattering the η meson on the clusterized (K * K * ) f 0 (1710) system, we find a peak in the modulus squared of the three-body scattering amplitude and it can be associated as a bound state with quantum numbers I G (J P C ) = 0 + (0 −+ ). Its mass and width are around 2054 MeV and 60 MeV, respectively. This state could be associated to the η(2100) meson. For the π(K * K * ) f 0 (1710) scattering, we find a bump structure around 1900-2000 MeV with quantum numbers 1 − (0 −+ ). While for the K(K * K * ) f 0 (1710) system, there are three structures. One of them is much stable and its mass is about 2130 MeV. It is expected that these theoretical predictions here could be tested by future experimental measurements, such as by the BESIII, BelleII and LHCb collaborations.

Studies of exotic hadrons such as the χc1(3872) state provide crucial insights into the fundamental force governing the strong interaction dynamics, with an emerging frontier to investigate their production in high energy collisions where a partonic medium is present. The latest experimental measurements from the Large Hadron Collider show an intriguing evolution pattern of the χc1(3872)-to-ψ(2S) yield ratio from proton-proton collisions with increasing multiplicities toward proton-lead and lead-lead collisions. Here we propose a mechanism of medium-assisted enhancement for the χc1(3872) production, which competes with the more conventional absorption-induced suppression and results in a nonmonotonic trend from small to large colliding systems. Realistic simulations from this model offer a quantitative description of all available data. Predictions are made for the centrality dependence of this observable in PbPb collisions as well as for its system-size dependence from OO and ArAr to XeXe and PbPb collisions. In both cases, a nonmonotonic behavior emerges as the imprint of the competition between enhancement and suppression and can be readily tested by future data.
