      abstract     = {We study the use of higher-order resummation for transverse
                      observables to achieve NNLO+PS matching within the GENEVA
                      framework. In particular, we embed $q_T$ resummation for
                      colour-singlet production at NNLL$'$ obtained via
                      soft-collinear effective theory and implemented in the
                      library SCETlib within GENEVA. We also study for the first
                      time the use of the generalised $N$-jettiness variable in
                      shower matching, and achieve the resummation of the
                      one-jettiness defined with transverse measures up to NLL$'$
                      accuracy. As a case study, we use these resummed
                      calculations to construct a \geneva NNLO+PS generator for
                      Higgs boson production in heavy-quark annihilation (with
                      beauty or charm-quarks in the initial state). The use of
                      transverse measures facilitates the matching to showers
                      ordered in transverse momentum, and opens the door to
                      possible future extensions of this approach to the
                      production of colour singlets in association with
                      final-state jets.},
