      abstract     = {A study of angular correlations inside jets induced by
                      gluon polarization is performed using proton-proton
                      collisions at a center-of-mass energy of $\sqrt{s}$ = 13.6
                      TeV. The data correspond to an integrated luminosity of 34.7
                      fb$^{-1}$, collected in 2022 with the CMS detector at the
                      LHC. The details of the parton shower are investigated using
                      jets reconstructed with the anti-$k_\mathrm{T}$ algorithm
                      and subsequently declustered with the Cambridge$-$Aachen
                      algorithm. A novel analysis technique is developed to
                      identify characteristic features of the jet substructure and
                      to select intermediate gluon splittings into quark-antiquark
                      pairs. An observable sensitive to gluon polarization in the
                      parton shower is measured and compared with PYTHIA 8 and
                      HERWIG 7 model predictions, with and without angular
                      correlations induced by the gluon spin. The results are
                      consistent with models that incorporate gluon polarization
                      and strongly disfavor those that neglect them.},
