Exploring the nature of exotic multiquark candidates such as the X(3872) plays a pivotal role in understanding quantum chromodynamics (QCD). Despite significant efforts, consensus on their internal structures is still lacking. We demonstrate a novel approach to help address this problem by studying the X(3872) production in heavy ion collisions, where a hot fireball with ample light as well as cha

Exotic hadrons and candidates-1
Track: Exotic Hadrons and Candidates
In this talk I will discuss what lessons can be learned about the structure of the famous X(3872) from the study of its yield in high-multiplicity pp collisions.
In particular, I will comment on some recent data by the LHCb collaboration, and how well they are reproduced under the assumption of a compact tetraquark state or a loosely bound molecule.

The dependence of the production of the $X(3872)$ meson on the hadron multiplicity in pp collisions has been used as evidence against X being a charm-meson molecule. A simple modification of the comover interaction model gives excellent fits to the data from the LHCb collaboration on the multiplicity dependence of the production of $X$ and $\psi(2S)$, giving a range of compatible values for react

The ALICE Collaboration has carried out measurements of
K$^0_{\rm S}$K$^{\rm \pm}$ interactions with pp collisions at $\sqrt{s}=7$ TeV and Pb--Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV to study the $a_0(980)$ meson, which is a tetraquark candidate, using the method of two-particle femtoscopy. Using a simple geometric argument, our results are found to be compatible with the interpretation of
