# How to type this symbol in LaTeX (commonly used to denote a sector)? [duplicate]

I'm sorry to ask such an elementary question. I am wanting to know how to type the following symbol in LaTeX, it is written with a subscript 'l' in the image below,

I feel quite illiterate because I don't even know how to read this symbol. I have tried typing the (English) alphabet in various font styles but nothing matched.

Many thanks
