T-even transverse momentum dependent gluon fragmentation functions in a spectator model

We present a model calculation of transverse momentum dependent (TMD) gluon fragmentation functions for the spin-1/2 and spin-0 hadrons. The is based on assumption that time-like off-shell can fragments into hadron single spectator particle. So far such models have only been used to calculate TMD distribution quark gluons. gluon-hadron-spectator coupling described by an effective vertex containing two form factors. obtain analytic expressions four T-even gluon. also numerical results $z$-dependence $k_T$-dependence functions. Our study shows effects these may be significant could probed future experimental measurements.
