Discussion about ultra-light FIPs

• Go to Indico Event

Goal of the meeting: start discussing about benchmarks for ultra-light FIPs
in particular for ultra-light dark scalars where different models/ parameters are used depending on the mass range.

In this discussion we should approach the (very) relevant issue raised by Maxim about the role of technical naturalness in model building for ultra-light scalars: “Should technical naturalness be a guiding principle in arranging and analyzing these models? Or should one discard it altogether arguing that so naturalness criterion is perhaps too restrictive?”
