We present a demonstration of the in-flight polarization angle calibration for the JAXA/ISAS second strategic large class mission, LiteBIRD, and estimate its impact on the measurement of the tensor-to-scalar ratio parameter, r, using simulated data. We generate a set of simulated sky maps with CMB and polarized foreground emission, and inject instrumental noise and polarization angle offsets to the 22 (partially overlapping) LiteBIRD frequency channels. Our in-flight angle calibration relies on…

TLDR
An excess of B-mode power over the base lensed-ΛCDM expectation is found in the range 30 < ℓ < 150, inconsistent with the null hypothesis at a significance of >5σ, and it is shown that systematic contamination is much smaller than the observed excess.
