Muon cooling: a race against time

• Giuseppe Lospalluto (ETH Zurich)

Room: WBGB/021 (TimeOut) 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?

A Glimpse into the Early Universe through Phase Transitions

• Lisa Biermann

Room: WBGB/021 (TimeOut) 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.
