The STAR experiment at the Relativistic Heavy Ion Collider (RHIC) atBrookhaven National Laboratory (BNL) is carrying out a spin physics programcolliding transversely or longitudinally polarized proton beams at = 200-500GeV to gain deeper insigh t into the spin structure and dynamics of the proton.These studies provide fundamental insight into Quantum Chromodynamics (QCD).One of the main objectives is the determination of the polarized gluondistribution function, g, through the measurement of the longitudinaldouble-spin asymmetry, ALL, for various processes. Inclusive hadron and jetproduction from polarized pp collision data collected so far at = 200 GeV usingthe STAR detector at RHIC have placed important constraints on g. Di-jetproducti on provides direct access to the initial parton kinematics at leadingorder (LO) QCD and thus provides sensitivity to the Bjorken-x dependence of g.The status of the mid-rapidity di-jet cross section analysis from the 2005 RHICrun and the longitudinal d ouble-spin asymmetry at mid-rapidity for the 2006data sample are discussed in these proceedings. Projections on future di-jetmeasurements at STAR are provided.

Status and prospects of Di-jet production in high-energy polarized proton-proton collisions at RHIC at s**(1/2) = 200-GeV
