Popis: The recently proposed superbosonization of the bcβγ (ghost-superghost) theory in terms of the ϕ ϕ ψ ψ system is extended to a globally defined operator realization of the ghost-superghost system on higher-genus Riemann surfaces. The bosonization formulae which make sense globally over the Riemann surface acquire new operator factors, absent in the local case, which explicitly break the global world-sheet supersymmetry. The βγ correlation functions which follow from the ϕ ϕ ψ ψ presentation (related to the phase II bosonization) differ from those known previously (which are in turn related to phase I bosonization). The difference is due to a rearrangement of the “extra” theta functions and hence the positions of the spurious poles. This rearrangement should compensate for the alterations of the structure of picture-changing operators in phase II.
