Abstract

Antiproton annihilation at rest in gaseous hydrogen (16 bar pressure) to the final states ρ(770)X andf 2(1270)X, whereX stands for one or more neutral mesons, has been studied at LEAR using the CPLEAR detector. Relative branching ratios are given forX =π 0,2π 0, 3π 0 ω in the ρ case, and forX =π 0, η in thef 2 case. The annihilation channel\(\bar pp \to \rho 3\pi ^0 \) has not been measured before. The fraction of P-wave annihilation is deduced from the ratiof 2 π 0/ρπ 0 to be 0.38±0.07, in good agreement with the result previously obtained by CPLEAR from the ratioK + K -/π + π -.
