We are pleased to announce that the upcoming EXCESS24 Workshop is taking place in the Physics Department of the Roma University, Sapienza, Roma, on July 6th, 2024.

This workshop, the fifth of the series, will be held as a satellite meeting to the 15th International Workshop on the Identification of Dark Matter 2024 (IDM 2024, LNGS, L'Aquila).

The main goal of the EXCESS workshop series is to provide a platform for comprehensive discussion on low-energy excesses observed in low-threshold dark matter and CEνNS experiments. 

Frequent contributors to the workshop were in previous iterations the DAMIC, SENSEI, DAMIC-M, CONNIE/SkipperCCD, CRESST-III, EDELWEISS/Ricochet, NUCLEUS, SuperCDMS-HVeV, SuperCDMS-CPD/SPICE/HeRALD experiments, and many others.
