Near-to-Far Extrapolation in Transverse Momentum at NOvA

NOvA is long-baseline neutrino oscillation experiment at Fermilab. In the NOvA $\nu_{\mu}$ disappearance and $\nu_{e}$ appearance analyses the Far Detector (FD) spectrum is predicted by extrapolating the $\nu_{\mu}$ charged current event spectrum at the Near Detector (ND) to the FD. ND and FD differences in selection efficiency and acceptance lead to uncertainties in the measured oscillation parameters. Extrapolating the ND spectrum to the FD in transverse momentum of the final state lepton helps account for these differences and reduces uncertainties in the measured oscillation parameters. This poster presents the results of extrapolating in transverse momentum in the 2020 NOvA $\nu_{\mu}$ disappearance and $\nu_{e}$ appearance joint analysis.
