Setkání CZ HEP komunity 2025 / Meeting of CZ HEP community 2025

Tuesday 28 Jan 2025, 09:00 → 14:00 Europe/Prague

pavilon SOLID-21 / pavilion SOLID-21 (FZU)

Regular meeting of HEP community in the Czech Republic. 

This meeting is dedicated to discussing issues for the forthcoming update of the European Strategy for HEP. The main topic of the strategy is the choice of the next collider at CERN. Which accelerator should be built at CERN, for what reasons and what are the alternatives. What other topics should particle physics research in Europe address? The full list of questions can be found here.

We are looking forward to your participation.
       Jana Faltová, Rupert Leitner, Zdeněk Hubáček a Jaroslav Zálešák

Question 1: Main collider project

1. Which is the preferred next major/flagship collider project for CERN?

2. What are the most important elements in the response to (1)?

• Physics Potential

• Long-term perspective

• Financial and human resources: requirements and effect on other projects

• Timing

• Careers and training

• Sustainability

1. Should CERN/Europe proceed with the preferred option set out in (1) or should alternative options be considered

• if Japan proceeds with the ILC in a timely way?

• if China proceeds with the CEPC on the announced timescale?

• if the US proceeds with a muon collider?

• if there are major new (unexpected) results from the HL-LHC or other HEP experiments?

10:15 → 10:45 R&D topics

Presentation (15 min)
Discussion (15 min)

Speaker: Peter Svihra (Czech Academy of Sciences (CZ), Czech Technical University in Prague (CZ))

• Beyond the preferred option in Question 1 (previous contribution), what other accelerator R&D topics (e.g. highfield magnets, RF technology, alternative accelerators/colliders) should be pursued in parallel? 
• DRD collaborations

10:45 → 11:10 Coffee break

11:10 → 11:25 Early Career Researchers view

Speaker: Pavel Vana (Charles University (CZ))

11:25 → 12:15 Non-collider projects

Presentation (15 min)
Discussion (35 min)

Speaker: Jaroslav Zalesak (Czech Academy of Sciences (CZ))

Qeustion 2: Non-collider projects

The remit given to the ESG also specifies that “The Strategy update should also indicate areas of priority for exploration complementary to colliders and for other experiments to be considered at CERN and at other laboratories in Europe, as well as for participation in projects outside Europe.” It would thus be most useful if the national inputs explicitly included the preferred prioritisation for non-collider projects. Specific questions to address:

1. What other areas of physics should be pursued, and with what relative priority?

2. What are the most important elements in the response to (1)? The set of considerations in section 1.1 (2) should be used.

3. To what extent should CERN participate in nuclear physics, astroparticle physics or other areas of science, while keeping in mind and adhering to the CERN Convention? Please use the current level and form of activity as the baseline for comparisons.

12:15 → 13:00 Other projects in US, Japan, P5 Strategy, NuPECC

Presentations (15 min US, 10 min Japan)
Discussion (20 min)

Speakers: Jana Bielcikova (Czech Academy of Sciences (CZ)), Zdenek Dolezal (Charles University (CZ))
