3169 — The Existing Chiral Exit Route Supplies an Ideal Polarimeter

Result

The protected decay $A\to B+n$, followed by the existing chiral exit $B\to q_R+X$, admits compatible flip charges and simultaneous positive threshold margins.

In the massless perfect-transfer limit, the exit-quark angular distribution has signed moment

$$3W\langle\cos\theta\rangle=u-v, \qquad W=u+v.$$

The two-port response determinant is minus two. No reverse decay or added reference port is required.

Limit

Finite-mass spin transfer, reconstruction of $X$, acceptance, backgrounds, resolution, and covariance remain uncalibrated. This is a source-derived ideal cascade, not yet an actual detector instrument or numerical selector.
