Consider a Brownian excursion from 0 to 1 in the upper half-plane. It (possibly) makes excursions above the horizontal line of height $t>0$. For each such excursion, one records the difference between its ending point and its starting point. This collection of real numbers, seen as a process in $t$, evolves like a growth-fragmentation process that we characterize. Joint work with William Da Silva.
