Remove text before and after a slash

The title and artist fields contain the same data in this format:

The Artist Name/The Track Title

I am looking for two regular expressions to remove the text before the / and to remove the text after the slash. Guess values doesn't work.

This was my best guess (but it fails to make any changes:
Field: TITLE
Original: ^.*/
Replace With: (this is left blank)

Field: ARTIST
Original: /*$
Replace With: (this is left blank)

Could you please help with these two expressions?

You could try it with Convert Tag -> Tag to see the immediate preview:
Field: TITLE
$regexp(%TITLE%,(.*)\/(.*),$1)
would leave the part in front of the slash /

and
$regexp(%TITLE%,(.*)\/(.*),$2)
would leave the part after the slash /

Please be careful with values that contains a slash itself, like AC/DC or This/or/that/or/something/else

It seems that you don't have to escape the slash in Mp3tag, so even
$regexp(%TITLE%,(.*)/(.*),$1)
should work.

You can check your real cases here:

That worked perfectly! (with a slight modification)
Thank you!!

Convert Tag -> Tag
Field: ARTIST
$regexp(%ARTIST%,(.*)\/(.*),$1)

and
Field: TITLE
$regexp(%TITLE%,(.*)\/(.*),$2)

If you are not not too friendly with regular expression, you could also use an action of the type "Guess value"
Source string: %title%
Guessing format string: %artist%/%title%
