Notes on the static parity non-conserving internucleon potential

G Barton - Il Nuovo Cimento (1955-1965), 1961 - Springer
If the weak Lagrangian density ℒ consists of self-interacting charged currents, the inclusion
into these of a term linear in the pion field leads to a static parity non-conserving …

Lifetime of the Neutral Pion

G Harris, J Orear, S Taylor - Physical Review, 1957 - APS
A new upper limit on the π 0 lifetime has been obtained by using 12 K π 2+ endings in
nuclear emulsion where the π 0 decays by a direct pair, π 0→(e++ e−)+ γ. The distance …
