Axions beyond the dark matter paradigm

29 Jan 2024, 09:00 → 31 Jan 2024, 23:00 Europe/Vienna

DESY in Hamburg

Andreas Ringwald (T (Cosmology)), Axel Lindner (ALPS (ALPS _ Any Light Particle Search)), David Tanner (University of Florida), Isabella Oceano (ALPS (ALPS _ Any Light Particle Search)), Manuel Meyer (University of Southern Denmark)

In May 2023 the experiment ALPS II at DESY in Hamburg started its search for axions and other WISPs with a purely laboratory-based approach. 

Preparations for the start of construction of the helioscope BabyIAXO are on its final stretch. 

This workshop aims at exploring the physics prospects of WISP searches not relying on the dark matter paradigm, but also taking into account the prospects of direct dark matter searches.

The number of participants is limited to 50 persons. Registration will start end of November.
