PASCOS 2026, the 31st International Symposium on Particles, Strings, and Cosmology, will be held in Sheffield from June 22 to 26, 2026. The conference aims to highlight recent advances in particle physics, astroparticle physics, string theory, and cosmology, with a strong focus on the interplay between these fields.

The conference includes invited plenary talks and parallel sessions. We warmly encourage participation from early-career researchers, and submission of abstracts for contributed talks and posters.

Topics will include:

LHC physics, dark matter and dark energy, string theory, neutrino physics, precision measurements, non-accelerator probes of new physics, inflation, gravitational waves, cosmic tensions, and modified gravity.
