Olive; Webb23 jan. 2024 · This work represents an extension of the single pion production model proposed by Rein [Z. Phys. C 35, 43 (1987).]. The model consists of resonant pion production and nonresonant background contributions coming from three Born diagrams in the helicity basis. The new work includes lepton mass effects, and nonresonance …

All mesons are unstable. The decays proceeding over a “long” time, as in the case of the neutron, are called weak. Even lifetimes of 10−13 seconds are still considered as “long” in elementary particle physics, and the decay is called weak. A particle with such a lifetime down to 10−11 sec leaves an observable trace

WebbPions. Pions (π–mesons) can be positive (π + ), negative (π –) or neutral (π 0) The anti–particle of the positive pion is the negative pion (and vice versa) The neutral pion is its own anti–particle. Pions are the lightest mesons, making them more stable than other types of meson. They were originally discovered in cosmic rays and ...
