Workshop

New Physics from The Sky

Oct 04, 2021 - Nov 12, 2021



Abstract

The LHC and direct detection experiments have had the most interesting possible outcome: the observation of a Higgs boson in isolation. This has left a void in theoretical particle physics, making the traditional questions on the origin of the weak scale and on the nature of dark matter deeper and more confusing than ever. The field has responded by producing a number of ideas that trace the answer to these questions to the early history of the Universe.
At the same time a number of new probes of the evolution of the Universe are planned or are already taking data. This calls for a meeting place where particle physicists, astrophysicists and cosmologists can join forces to refine theoretical ideas, find new experimental targets and benefit from the expertise needed to answer the most pressing questions in fundamental physics. This workshop will offer to the particle physics community access to a wealth of present and future cosmological data. To astrophysics and cosmology it will give a window on the latest ideas that connect their disciplines to the fundamental laws of particle interactions.
We are on the brink of a new data-driven era in cosmology. This is the best time to bring these different communities together and pave the way for the next discovery in fundamental physics.



Topics
The schedule is
1. Oct 4-9: Dark matter in non-standard cosmologies
2. Oct 11-15: Astrophysics as a fundamental physics laboratory
3. Oct 18-22: Cosmological approaches to fine-tuning problems and their tests
4. Oct 25-29: Testing fundamental physics with low- and high-redshift cosmology
5. Nov 1-5: New physics in (primordial) gravitational waves
6. Nov 8-12: Symposium
A number of confirmed key participants will help leading the discussion around the topics above: Asimina Arvanitaki (Perimeter Institute), Xingang Chen (Harvard University), Julien Lesgourges (Aachen University), GĂ©raldine Servant (DESY, Hamburg University), Sergey Sibiryakov (Perimeter Institute), Tomer Volansky (Tel Aviv University).

The workshop will be held in presence. Given the still uncertain circumstances, we foresee all seminars to take place also online, independently of the travel restrictions in the Fall. If you wish to apply to the online activities only, please write it explicitly in the comment section of the application form. Thank you for your cooperation. More detailed information will be sent to the participants closer to the dates of the workshop.
