Abstract
IceCube is a one cubic kilometer neutrino telescope at the South Pole. Its primary goal is to discover high energy cosmic neutrinos and anti-neutrinos from astrophysical sources. Observation of the spectrum near the characteristic energy $E_\nu\approx6.3\,\mbox{PeV}$ of the Glashow resonance, the interaction of anti-neutrinos with atomic electrons via $\bar{\nu}_e+e^{-}\rightarrow W^{-}$, is of particular interest. Since the cross section for this process can be calculated from first principles, it is possible to quantify separately the fluxes for neutrinos and anti-neutrinos if the resonance is observed above a continuum. In turn, such a separation will give unique insights into the astrophysics properties of the sources.\\ We conducted the first IceCube performance studies and optimizations for likelihood-based algorithms to reconstruct (anti-)neutrino-induced particle showers (cascades) in the energy range of the Glashow resonance using simulated data from electron (anti-)neutrino Monte Carlo generators and detector response simulations. For hadronic showers in the energy range $1\,{\rm{PeV}}
