We present a detailed assessment of the dynamical pathways leading to thecoalescence of compact objects in Globular Clusters (GCs) and Short Gamma-RayBurst (SGRB) production. We consider primordial binaries, dynamically formedbinaries (through tidal two-body and three-body exchange interactions) anddirect impacts of compact objects (WD/NS/BH). We show that if the primordialbinary fraction is small, close encounters dominate the production rate ofcoalescing compact systems. We find that the two dominant channels are theinteraction of field NSs with dynamically formed binaries, and two-bodyencounters. We then estimate the redshift distribution and host galaxydemographics of SGRB progenitors, and find that GCs can provide a significantcontribution to the overall observed rate.  We have carried out hydrodynamical modeling of evolution of close stellarencounters with WD/NS/BH, and show that there is no problem in accounting forthe energy budget of a typical SGRB. The particulars of each encounter arevariable and lead to interesting diversity: the encounter characteristics aredependent on the impact parameter, in contrast to the merger scenario; thenature of the compact star itself can produce very different outcomes; thepresence of tidal tails in which material falls back onto the central object atlater times is a robust feature of these calculations, with the mass involvedbeing larger than for binary mergers. It is thus possible to accountgenerically in this scenario for a prompt episode of energy release, as well asfor activity many dynamical time scales later (abridged).
