A Possible Advanced Positron Signal in AMS-02 Measurements

Yi Yang

A time-symmetric transport hypothesis models positrons as an admixture of retarded and advanced components to explain their distinct spectrum from electrons in AMS-02 data.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We adopt a representative, order-of-magnitude benchmark, in which the advanced-associated component dominates the effective admixture but experiences a ten-fold reduction in effective radiative exposure, to dissect the underlying spectral components and verify the results against AMS-02 data.

C2weakest assumption

The positron sector can be modeled as an effective admixture of retarded and advanced-associated components whose advanced branch experiences a reduced effective radiative exposure; this reduction is introduced as a postulated ingredient requiring deeper theoretical justification, while spatial diffusion and solar modulation are omitted entirely.

C3one line summary

A time-symmetric transport hypothesis models positrons as an admixture of retarded and advanced components with ten-fold reduced radiative exposure to reproduce the separated energy scales in AMS-02 electron and positron spectra.
