The International Symposium on Lepton-Photon Interactions at High Energies is a biennial conference series sponsored by the International Union of Pure and Applied Physics (IUPAP). The 27th edition of the series is taking place in Ljubljana, hosted this year by the University of Ljubljana and the Jožef Stefan Institute.
The Lepton-Photon series is a major high-energy physics conference organized biennially under the auspices of the IUPAP C11 Commission on Particles and Fields. The conference programme is traditionally based on invited plenary reviews. The session topics this year range from highlights of Run 2 at the LHC to dark matter and dark energy.
