Decay of a high-energy pion beam in a medium: Formation of a decay channel
Askar'yan G. A.
The nonlinear transport of a pion beam in a medium is analyzed. The energies of the pion beams from the latest generation of accelerators are sufficient to reduce the density of the medium (a gas or liquid) and to form a decay channel which reduces the energy loss and angular divergence of a beam of pions and neutrinos.
