Final answer:
The decay mode of Ω⁰ → Ξ⁰ + π⁻ produces Ξ⁰ and π⁻ particles.
Step-by-step explanation:
The decay mode of Ω0 → Ξ0 + π- produces the following particles:
Ξ0 - a particle belonging to the family of hyperons
π- - a negatively charged pion
These are the particles that are produced in this decay mode.
