LiteBIRD science goals and forecasts: improving sensitivity to inflationary gravitational waves with multitracer delensing

We estimate the efficiency of mitigating the lensing B -mode polarization, the so-called delensing, for the LiteBIRD experiment with multiple external data sets of lensing-mass tracers. The current best bound on the tensor-to-scalar ratio, r , is limited by lensing rather than Galactic foregrounds....
