Resonant behaviour in double charge exchange reaction of π^+ mesons on the nuclear photoemulsion

Yu. A. Batusov, T. D. Blokhintseva, F. Balestra +4

The invariant mass spectra of the $pp{\pi }^{-}$ and $pp$ systems produced in the double charge exchange (DCX) of positively charged pions on photoemulsion are analysed. A pronounced peak…
