             abstract = "Even though plenty of symbiotic stars (SySts) have been found in 
                         the Galactic field and nearby galaxies, not a single one has ever 
                         been confirmed in a Galactic globular cluster (GC). We investigate 
                         the lack of such systems in GCs for the first time by analysing 
                         144 GC models evolved with the MOCCA code, which have different 
                         initial properties and are roughly representative of the Galactic 
                         GC population. We focus here on SySts formed through the 
                         windaccretion channel, which can be consistently modelled in 
                         binary population synthesis codes. We found that the orbital 
                         periods of the majority of such SySts are sufficiently long (103 
                         d) so that, for very dense GC models, dynamical interactions play 
                         an important role in destroying their progenitors before the 
                         present day (\∼1112 Gyr). In less dense GC models, some 
                         SySts are still predicted to exist. However, these systems tend to 
                         be located far from the central parts (70 per cent are far beyond 
                         the half-light radius) and are sufficiently rare (1 per GC per 
                         Myr), which makes their identification rather difficult in 
                         observational campaigns. We propose that future searches for SySts 
                         in GCs should be performed in the outskirts of nearby low-density 
                         GCs with sufficiently long half-mass relaxation times and 
                         relatively large Galactocentric distances. Finally, we obtained 
                         spectra of the candidate proposed in \ω Cen (SOPS IV e-94) 
                         and showed that this object is most likely not a SySt.",
