Jet production in polarized p+p collisions at √(s) = 200 GeV and √(s) = 500 GeV provides a powerful probe to study gluons inside the proton. The Solenoidal Tracker at RHIC (STAR) has the capability, with nearly full azimuthal (2π) coverage, to reconstruct jets at mid-rapidity (|η| < 1). The latest STAR inclusive jet longitudinal double-spin asymmetry ALL measured in 200 GeV p+p collisions provides better constraints on the polarized gluon distribution Δg(x) for 0.05
