The 7th edition of the International Conference on the Initial Stages in High-Energy Nuclear Collisions will be held June 19-23, 2023 in Copenhagen. The conference is organized by the Niels Bohr Institute, University of Copenhagen. It is dedicated to new experimental results from LHC and RHIC, the developments in theoretical tools that predict and explain recent phenomena observed in experiments, as well as the plans for future experimental facilities including EIC and FAIR. The main topics of focus will be:


  • Partonic structure of protons and nuclei  
  • Physics at low-x and gluon saturation      
  • The initial stages and nuclear structure in heavy-ion collisions 
  • Collective dynamics from small to large systems 
  • New theoretical techniques at large and small coupling 
  • New facilities: DIS and hadronic experiments 


The conference format will be in-person. 


Conference venue: The plenary sessions will be held at Lundbeckfond Auditoriet (Ole Maaløes Vej 5, 2100 Copenhagen), and the parallel session will take place at H.C. Ørsted Instituttet (Universitetsparken 5, 2100 Copenhagen). It takes about 5 minutes to walk from one to the other.


Travel: Copenhagen has good flight connections to all major cities worldwide. The conference venue, located at the University of Copenhagen, can be easily reached via public transportation within 40 minutes from the airport.


Accommodation: Participants are asked to arrange their accommodation themselves. As Copenhagen is a popular tourist city worldwide, and June is a busy season, we recommend booking your hotel as early as possible. 


Financial support: We will provide supports for students and young postdocs who have limited financial support from their home institutes. Instructions for applications are available on the website.


The most updated information will be available on this website.
