Top LHC France 2026

26 mai 2026, 13:30 → 27 mai 2026, 17:30 Europe/Paris

Amphi Charpak (LPNHE)

The Top LHC France workshop series aims to foster, at a national level, all research activities connected to the physics of the top quark. These meetings hence allow for theoretical and experimental high energy physicists working in France to informally discuss the recent LHC results. A particular emphasis is put on results that originate from the work performed in the French laboratories and new collaborations are also encouraged.

The first editions of the Top LHC France workshops were mostly oriented towards precision measurements in the top sector. With the LHC increase in energy and luminosity, the discussion started to focus, for the last couple of years, on processes and measurements where new physics could be hiding. The same considerations are driving the agenda of the 2026 workshop. 

Although most participants are working in French laboratories, the workshop is open to international participants who have strong links with France.

2026 edition will be held on the Pierre et Marie Curie campus of the Sorbonne University in Paris.
