DESCRIPTION:Speakers: Francesco Giovanni Celiberto (UAH Madrid)\nWe presen
 t the first comprehensive study of fragmentation into fully heavy tetraqua
 rks\, based on the newly released TQ4Q1.1 set of collinear\, variable-flav
 or-number-scheme fragmentation functions. Covering scalar ($0^{++}$)\, axi
 al-vector ($1^{+-}$)\, and tensor ($2^{++}$) configurations\, our analysis
  provides a pioneering framework to explore exotic-matter production with 
 precision QCD tools. For the first time\, we quantify and propagate key so
 urces of uncertainty\, from color-composite long-distance matrix elements 
 to missing higher-order contributions in both the hard and fragmentation s
 ectors. This work offers a robust reference for ongoing analyses at the LH
 C and for future explorations at its High-Luminosity upgrade and next-gene
 ration accelerators. As an outlook\, we discuss the potential of a multimo
 dal fragmentation strategy\, aimed at combining different production mecha
 nisms\, including diquark clusters and molecular components\, to further r
 efine predictions and improve the connection between QCD dynamics and exot
 ic matter phenomenology.\n\nhttps://indico.ific.uv.es/event/8035/contribut
