Lensing B-Mode Amplitude Expected from a Torsion-Regulated Bounce

This paper computes the lensing B power at ell 80 expected in a cosmology whose early collapse is regulated by spin torsion, and compares the result with Planck and BICEP measured lensing B amplitude at ell 80 in microK squared. The predicted value is 0.42 microK squared, against a comparison value of 0.45 microK squared, a ratio of 0.933 and a separation factor of 1.07. The calculation starts from the Aldred Limit density for neutron matter, 9.72e+54 grams per cubic centimetre, follows the stated thermal and late-time assumptions for this channel, and keeps every intermediate step in the deposited code. The result is consistent with the published value at the level the comparison allows, and the paper states plainly which future sensitivity would turn that consistency into a discriminating test. No new observation is reported. The study is simulated and computed from stated assumptions, not measured, and its headline numbers are 0.42, 0.45 and 0.933 for the predicted value, the comparison value and their ratio respectively.
