Quark Matter 2025
Project Snapshot
Multi-Venue Heavy-Ion Physics at FAIR/GSI
Quark Matter 2025 returned to Germany for the first time since the FAIR facility began commissioning, drawing roughly 1,100 physicists to Frankfurt am Main. Sessions were split between the Kap Europa congress centre in the city centre and the GSI/FAIR campus in Darmstadt—about 30 km apart—making venue navigation the LOC’s top concern.
Bridging Two Venues with Push Notifications
Shuttle buses connected the two sites, but timing was tight. HEPCon’s push notifications included venue tags so attendees could see at a glance whether a session change affected their current site or required a bus ride. The LOC used targeted pushes to alert only attendees whose favourited sessions were affected, reducing notification fatigue.
Poster Programme with Experiment Filters
With more than 450 posters spanning ALICE Run-3 results, CBM@FAIR predictions, HADES measurements, and lattice QCD calculations, the poster hall in Frankfurt was one of the densest in QM history. HEPCon’s poster browser let attendees filter by experiment, theory sub-field, or keyword, and save a shortlist for the evening reception.
Offline-Ready for Underground Sessions
Several plenary sessions took place in a below-ground auditorium at Kap Europa with limited cellular signal. HEPCon’s service-worker caching ensured attendees could still browse timetable entries, read abstracts, and check their favourites list without connectivity.
The Challenge
- • Navigate a split-venue conference across Frankfurt and Darmstadt
- • Manage 450+ posters with experiment and topic filters
- • Provide offline access in underground / low-signal auditoriums
The Solution
HEPCon synced the QM 2025 programme from CERN Indico and delivered it as a PWA with venue-aware push notifications. Poster-browsing filters covered every major experiment and theory sub-field. Offline caching ensured access in the below-ground auditorium and during bus transfers between sites.
The Results
- Venue-aware pushes reduced confusion during cross-site session changes
- Poster filters covered ALICE, CBM, HADES, and lattice QCD contributions
- Offline caching handled underground and in-transit connectivity gaps
"Splitting across two venues would have been chaotic without venue-tagged push notifications."
