Description

The workshop is organized by A.I. Alikhanyan National Science Laboratory (Yerevan Physics Institute) and Yerevan State University (YSU) and will be held on September 29 – October 3, 2025 in Yerevan, Armenia. This is the second event of regular Yerevan-CHEP conference series dedicated to experimental and theoretical High Energy Physics.

The main topics of the current event are the Physics of LHC and Higgs boson, Physics of High Energy Muons, Physics Beyond the Standard Model, Hadron Spectroscopy, Heavy Ion Physics, Spin Physics, Advanced Computational and Analysis Tolls in HEP, etc. Areas of interest include topics of High Energy Physics experiments such like experiments at LHC, SPS, NICA, KEK, CEBAF, etc.   

The conference expects around 60 talks, with duration of about 20-30 minutes.

The participation fee is 150 euros. The social expenses (including coffee breaks, reception, conference dinner, and excursion) will be partially covered by the organizers and partially funded through the participation fee. Accommodation and travel expenses are expected to be covered by the participants. The organizers can assist in arranging accommodation at special reduced rates. Additionally, we have limited funds available to cover accommodation and travel expenses.

 

The opening and the first day of the conference will take place at YSU (1 Alek Manukyan St., Central Building, 5th floor).

All following days of the conference will be held at the AANL (2 Alikhanyan Brothers St., Yerevan).
