Query: Ground state heavy tetraquark production in heavy quark fragmentation   During recent years, the study of exotic hadrons including tetraquarks and
pentaquarks has attracted a lot of interests and more studies are in progress
experimentally and theoretically. It is well-known that at sufficiently large
transverse momentum the dominant production mechanism for standard heavy
hadrons (mesons/baryons) is actually the fragmentation so that the same
mechanism is also proposed for the production of heavy exotic hadrons. This
work is the first attempt to study the direct fragmentation of a heavy quark
into ground state heavy tetraquarks in leading order of perturbative QCD. In
this regard, we will present an exact analytical expression for the
fragmentation production of neutral hidden flavor tetraquarks
$(Qq\bar{Q}\bar{q})$ which includes most of the kinematical and dynamical
properties of the process.
