Abstract

The annihilation of p ̄p at rest into KL0KS0π0 and KL0KS0η was investigated with the Crystal Barrel detector at LEAR. These final states with negative C-parity are dominated by φ and K0* resonances. The ratios of the branching ratios are B( p ̄p→φπ0) B( p ̄p→φη)=8.3±2.1 and B( p ̄p→K0 K ̄0*+ K ̄0K0*→KL0KS0π0) B( p ̄p→φπ0→KL0KS0π0)= 2.04±0.21.
