$\tau^- \to \omega \pi^- \nu_\tau$ decay in R$\chi$T with tensor sources

Feng-Zhi Chen, Xin-Qiang Li, Yuan-He Zou

The forward-backward asymmetry in τ to ωπν decay arises only from tensor new physics and provides its clean probe.

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

the forward-backward asymmetry, which can only arise from a non-zero tensor interaction, provides a sensitive probe of this NP effect

C2weakest assumption

That resonance couplings fixed by QCD short-distance constraints, spectral function fitting, and chiral perturbation theory matching remain reliable when tensor new physics is added and do not introduce uncontrolled uncertainties in the asymmetry prediction.

C3one line summary

The forward-backward asymmetry in τ⁻ → ω π⁻ ν_τ decay provides a sensitive probe for non-standard tensor interactions in resonance chiral theory.
