AbstractThe inclusive hadroproduction of a Higgs boson and of a jet, featuring large transverse momenta and well separated in rapidity, is proposed as a novel probe channel for the manifestation of the Balitsky–Fadin–Kuraev–Lipatov (BFKL) dynamics. Using the standard BFKL approach, with partial inclusion of next-to-leading order effects, predictions are presented for azimuthal Higgs-jet correlations and other observables, to be possibly compared with experimental analyses at the LHC and with theoretical predictions obtained in different schemes.

One of the main objectives of the high-energy spin physics program at RHIC at BNL is the precise determination of the polarized gluon distribution function, Δg(x). Polarized [Formula: see text] collisions at [Formula: see text] GeV and at [Formula: see text] GeV at RHIC provide an unique way to probe the proton spin structure. Inclusive measurements, such as inclusive jet and hadron production, have so far been the prime focus of various results at [Formula: see text] GeV constraining Δg(x) for 0.05 < x < 0.2. A recent global analysis provides for the first time evidence of a non-zero value of the gluon polarization [Formula: see text]. First results of di-jet production at [Formula: see text] GeV by the STAR collaboration will allow a better constraint of the underlying event kinematics. Extending the current program to smaller values of x is a key goal for the future high-energy spin physics program at RHIC. Forward di-jet production measurements at STAR beyond the current acceptance from -1 < η < +2 to +2.5 < η < +4, in particular those carried out at [Formula: see text] GeV, provides access to low x values at the level of 10-3 where current uncertainties of Δg(x) remain very large. Those measurements will eventually be complemented by a future Electron-Ion Collider facility probing Δg(x) in polarized [Formula: see text] collisions.

The STAR Collaboration is performing a wide range of measurements to determine the gluon helicity distribution in the proton. Gluon-gluon and quark-gluon scattering dominate jet production in proton-proton collisions at RHIC, so the longitudinal double-spin asymmetry, [Formula: see text], for jet production places significant constraints on the gluon polarization in the proton. In recent years STAR has recorded large longitudinally polarized [Formula: see text] data sets at both [Formula: see text] GeV and [Formula: see text] GeV. The 2009 STAR inclusive jet [Formula: see text] measurements at [Formula: see text] GeV show the first experimental evidence of non-zero gluon polarization over the Bjorken-[Formula: see text] range, [Formula: see text]. Furthermore, data collected at [Formula: see text] GeV during the 2012 and 2013 RHIC runs allow access to the gluon polarization at lower [Formula: see text]. In this talk, I will present the final results of the 2009 inclusive jet [Formula: see text] measurement at [Formula: see text] GeV, the analysis status of the 2012 inclusive jet [Formula: see text] measurement at [Formula: see text] GeV, and the status of di-jet and other STAR measurements that are sensitive to gluon polarization.
