Abstract
Let be a complete discretely valued field of residue characteristic not 2 and its ring of integers. We explicitly construct a regular model over with strict normal crossings of any hyperelliptic curve . For this purpose, we introduce the new notion of MacLane cluster picture, that aims to be a link between clusters and MacLane valuations.
