The 40th International Symposium on Physics in Collision
Aachen, Germany, 14-17 September, 2021

The International Symposium on Physics in Collision is a conference series that began in 1981 in Blacksburg, Virginia, USA. The program of the symposium is composed of invited talks and contributions in poster sessions. Invited speakers will review and upadate key topics in particle physics and related topics in which new results have been published in the last year or are reasonably expected to be so before the next symposium. The aim of presentations is to encourage informal disucssions of new experimental results and their implications. The topics at the symposia cover a wide range of physics subjects from accelerator-based particle physics to astroparticle physics.

Talks will be by invitation only. But we are happy to receive poster contributions from all participants. Please send abstracts to PIC2021@physik.rwth-aachen.de
