Are sub stories of Epic mapped as child stories of parent Epic story?

Let's say i have an Epic and that Epic has 5 sliced stories. Now should i have to create those 5 sub stories as child stories for Epic story or that can be created as separate stories where there is no dependencies b/w parent Epic and sub stories?

This is bit controversial question , since both options are practiced , but lets look at PMI-ACP exam perspective. PMI-ACP refers User Stories Applied by Mike Cohn as reference for exam and in that context, epic get dis-aggregated in small stories and once it is done epic is not more in existence, mean we do not have to remember that these stories came based on some earlier epic, epic loose its existence as it gets spitted in User Stories, and User Story is just a User Story it is not Child Story.

Thank you Saket for helping me to understand. So in that case, can i assign a Theme for those user stories created from a Epic for tracking and reporting purpose.

Yes.

Theme : Theme is a set of related user stories that may be combined together and treated as a single entity for either estimating or release planning.

Thank you Seema for confirming.
