Consideration is being given to upgrade the SuperKEKB electron-positron collider with the introduction of electron beam polarization as a means of accessing a unique precision electroweak physics program. The upgrade would enable Belle II to make a number of precise measurements, one of which is the left-right asymmetry present in the e+e-$\rightarrow$e+e- Bhabha scattering process. The expected level of precision in such a measurement will require the theoretical values of the asymmetry to be calculated at least to the next-to-leading order (NLO) level, and the implementation of simulation event generators with a similar level of precision. In this paper we compare the calculations of the ReneSANCe generator to those of an independent NLO calculation as well as make projections for the uncertainties expected in SuperKEKB/Belle II upgraded with polarized electron beams. |
