WebCharged pions were the first particles to be artificially produced in accelerators in the late 1940’s so we know quite a lot about them. Many varieties of atoms containing pions were studied between the 1950's and … WebThe pion absorption reaction + on Ar was studied at pion energies of 70, 118, 162, 239 and 330 MeV, and on N and Xe at 239 MeV. Absorption reaction channels with at least two energetic charged particles in the final state have been identified. WebI have seen the charged pion decay π − → ν ¯ ℓ + ℓ − represented with diagrams containing a W − in the s -channel. The π − and W − have angular momentum 0 and 1 respectively, though. How does this process conserve angular momentum? I see that this question has been asked before, but I haven't found an answers. particle-physics angular-momentum matthew eller
