17:30 → 17:50 Muon cooling: a race against time

Muons are born fast and die young, yet they play a central role for several precision experiments and new physics searches.
This talk explores muon cooling, the challenge of compressing a muon beam’s phase space before the particles decay.
From ionisation cooling to novel low-energy methods, we’ll ask: How to cool a particle beam that lives for microseconds?
What are the current proposed techniques? And what could future breakthroughs mean for the next generation of muon experiments?

18:30 → 18:50 A Glimpse into the Early Universe through Phase Transitions

Let us go on an adventure to "where no one has gone before": the early universe beyond reach of current direct observation methods. We might find an electroweak phase transition there!
Such a phase transition could help explain why we exist (along with all other matter). It may also leave a trace: a stochastic gravitational wave background. "Why?", "How?", and possible future observation strategies will be discussed in this talk.
