The (3pi)-nucleon collision in coherent production on nuclei at 40 GeV/c

Coherent 3\piproduction on nine different nuclear targets has been studied using a 40 GeV/c\pi^{-} beam at Serpukhov accelerator. Absorption in nuclear matter of the produced system has been measured by analysing the data on the different nuclear targets. Identical results are obtained from the diff...

Descripción
Sumario:Coherent 3\piproduction on nine different nuclear targets has been studied using a 40 GeV/c\pi^{-} beam at Serpukhov accelerator. Absorption in nuclear matter of the produced system has been measured by analysing the data on the different nuclear targets. Identical results are obtained from the differential cross sections and from the coherent nuclear cross sections. The 1^{+} waves show a very weak absorption, definitely smaller than 0^{-} and 2^{-} waves. No influence on the absorption comes from the spin-flip amplitudes, which have been found to be negligible in the coherent region.
