this is the result I'd like to achieve:
I tried various commands to make the forward slash larger, for instance I tried the \left. (...) \right /
or composing multiple \mathlarger
commands but I couldn't get the desired result, with both of them the forward slash is bigger than normal but not even close to be large enough.

, between\left.
and\right.
to get an extensible slash. This doesn’t work with every font out there, but it does with most of them.
