Abstract
We consider the phenomenology of glueball production and decay in theories with hidden glue. We focus on the case of folded supersymmetry (FSUSY), where there is an unbroken SU(3) gauge theory in the absence of light matter, leading to the formation of glueballs. We study their production through the annihilation of folded squarks into hidden gluons at the LHC, and model their fragmentation into glueballs. We obtain the distribution of displaced vertices, which is directly determined by the folded squark mass scale. Although here we specifically apply it to FSUSY, the procedure to model the hidden glue fragmentation into glueballs can be generalized to other similar theories.

Summary
We will focus on FSUSY in order to provide a complete example of the glueball parameters necessary to study the phenomenology of the associated hidden glue. If we consider the production through the charged current the preferred annihilation channel is into W ±γ This leads to bounds on the left-handed f-squark masses [34] which for the LHC Run I were just below 500 GeV. The charged pair production through an s-channel W ± was studied in [34] In this case the left-handed f-quarks decay back preferentially to W ±γ, resulting in bounds on mqL. The main parameter needed to compute both the fragmentation function and the decay of glueballs is their mass This is largely determined by the infrared scale defined by the hidden glue interactions, ΛIR. This gives us an estimate of the relation between MGand the typical folded gluon energy fragmenting into glueballs, which we will use to model the fragmentation function
