${{\mathit \Sigma}^{-}}$ DECAY PARAMETERS

See the ``Note on Baryon Decay Parameters'' in the neutron Listings. Older, outdated results have been omitted.

TRIPLE CORRELATION COEFFICIENT $\mathit D$ for ${{\mathit \Sigma}^{-}}$ $\rightarrow$ ${{\mathit n}}{{\mathit e}^{-}}{{\overline{\mathit \nu}}_{{{e}}}}$

INSPIRE   PDGID:

S020TC

The coefficient $\mathit D$ of the term $\mathit D$ $\mathbf {P}\cdot{}(\mathbf {\hat{{\mathit p}}}_{{{\mathit e}}}{\times }\mathbf {\hat{{\mathit p}}}_{{{\mathit \nu}}}$) in the ${{\mathit \Sigma}^{-}}$ $\rightarrow$ ${{\mathit n}}{{\mathit e}^{-}}{{\overline{\mathit \nu}}}$ decay angular distribution. A nonzero value would indicate a violation of time-reversal invariance.

VALUE EVTS DOCUMENT ID TECN  COMMENT $0.11$ $\pm0.10$ 50k HSUEH 1988 SPEC ${{\mathit \Sigma}^{-}}$ 250 GeV
