We are pleased to announce the 2026 edition of the LHC Days in Split conference. This is the 14th in the series of conferences designed to reinforce and further develop High Energy Physics in the Balkans, especially in connection with the LHC Project. The first 12 editions were held in Split, and this is a second edition on the beautiful nearby island of Hvar. The organizing institutions are the Faculty of Electrical Engineering, Mechanical Engineering and Naval Architecture (FESB) and the Faculty of Science (PMF) of the University of Split.
