The Small Triangle Meeting on theoretical physics is organized by the Institute of Experimental Physics, Kosice and Slovak Physical Society and will be held from October 24 to October 27, 2023 at the Arthotel Medzilaborce, north-east Slovakia.

This is already the 23-rd traditional international meeting since 1999. The main goal of this event will be focused on  the  last results in theoretical and phenomenological physics including various research areas  (solid state physics, high energy particle physics, complex systems, mathematical modeling of computational physics, etc). We would like to emphasize that mainly review and popularization talks will be prefered. Only 15-20 and 25-30 min. talks are assumed to be included.
