Description
The recently discovered abundance of hadrons with more than three valence quarks remains poorly understood. Measurements of these exotic hadrons and their interactions with the QCD medium provides a new avenue to investigate their properties. Additionally, the production of hadrons with more than three quarks presents new testing grounds for models of particle transport and recombination in hadron collisions. This talk will explore data on the exotic $X$(3872) and $T_{cc}^{+}$ hadrons, similarities in their properties, and differences in their production as a function of charged particle multiplicity in $pp$ collisions. We will also present the first measurement of the nuclear modification factor $R_{pA}$ for a four-quark state, the $X$(3872), in $p$Pb collisions. The outlook for future measurements in heavy ion collisions and with the LHCb fixed-target system SMOG II will be discussed.
