GDR-InF Annual Meeting 2026 — concluding the current mandate

16 nov. 2026, 14:00 → 18 nov. 2026, 13:30 Europe/Paris

Ibis Styles Troyes Centre (Troyes)

Overview

The 2026 GDR-InF Annual Meeting will take place from November 16 (afternoon) to November 18 (morning) at the Ibis Styles Troyes Centre. 

This meeting will conclude the current mandate of the GDR Intensity Frontier (2022–2026) and will provide an opportunity to review recent developments across the broad scientific programme of the GDR, discuss ongoing work, and look ahead to the scientific priorities and collaborations of the coming years.

Scope

As in previous editions, the meeting is intended to foster informal exchanges across experiment, theory and phenomenology, as well as among the different thematic communities represented within the GDR.

The programme will cover flavour physics, non-perturbative aspects of QCD, quark–lepton interplay, light new particles, discrete symmetries, and current and future experiments at the intensity frontier.

Participants, and in particular PhD students and postdoctoral researchers, are warmly encouraged to propose a contribution when registering.

Venue and Logistics

The venue is within walking distance of Troyes’ historic centre and is easily accessible by train from many French cities.

Accommodation and meals during the meeting will be covered by the GDR-InF. Travel to and from Troyes, as well as meals during the journey, will not be covered.
