This workshop began as a local seminar at TU Munich, contributing to the establishment of femtoscopy as a key tool for studying hadron-hadron interactions using ALICE data. It evolved into a workshop aimed at bringing together theoretical experts and experimentalists, resulting in numerous innovative techniques for analyzing femtoscopic data and fascinating results. This is the 3rd edition of FemTUM, and now we have officially internationalized it by hosting it in Sofia, Bulgaria.

In this edition, the program will focus on:

• Experimental prospects during RUN 3 of the LHC
• Using two- and three
