KEK Theory Meeting on Particle Physics Phenomenology (KEK-PH2020)

18 Feb 2020, 08:00 → 21 Feb 2020, 18:00 Asia/Tokyo

Kobayashi Hall, Kenkyu-Honkan bldg. 1F (KEK)

The annual Theory Meeting on Particle Physics Phenomenology (KEK-PH2020) will be held at KEK for 4 days from February 18 to 21, 2020.

This meeting covers many topics in Particle Physics and Cosmology, from the Standard Model and models beyond it to particle cosmology and astrophysics. We plan to discuss recent developments in modeling Physics Beyond the Standard Model with their phenomenological aspects and also learn about the latest results and status of various ongoing and planned experiments.

The meeting includes talks by invited speakers and short talks by participants. All the talks will be given in English. We aim to provide an opportunity, not only for experts but also for master/ph.D course students, to learn recent developments in particle physics phenomenology and to activate intensive discussions.

"School for future electron positron colliders" will be held after KEK-PH2020 (February 24-28, 2020). When you register KEK-PH, please kindly notify if you are also interested in attending the school. Separated registration though the left tab must be made to attend the school. 

Please note that the banquet this time has been cancelled. 

See this page again for your information.
