RACI chart for ISO 27001 controls

Answer:

First it is important to note that a RACI matrix is not mandatory for ISO 27001.
Considering that, there is no definitive RACI chart for this situation, because organizations are free to implement ISO 27001 controls as best fits them, but in a general manner the roles to include in such RACI matrix should consider at least:
- Top management / CISO as Accountable for controls implementation decisions
- Risk owners as Responsible for the overall controls implementation and operation
- Team members as Responsible for tasks / activities related to controls implementation and operation
- Units Heads / Processes Owners / Asset owners / Interested Parties as Consulted about controls to be implemented
- Employees / Users / as Informed about implemented controls
