Application of current algebra and partial conservation of axial-vector current to proton-antiproton annihilations
Journal Article

· Phys. Rev. D; (United States)
A soft-pion study using current algebra and the partially conserved axial-vector current (PCAC) hypothesis is made of the proton-antiproton annihilation process p-barp..-->..K/sup +/K/sup -/3..pi../sup 0/. Of the three neutral pions only two are considered as soft with the third pion forming part of the external final state. The differential rate for the process is normalized to the differential rate of the corresponding process without the soft pions. Theoretical predictions for the branching ratios at various antiproton momenta are compared with the existing experimental data.
