In this talk we study a new construction of loop Lie algebras via constructible functions on a space of Higgs bundles on some particular curves: the weighted projective lines. This allows a definition of new interesting basis. We also explain how this geometric setting leads to the concept of loop crystal, analogous to crystals but for loop Lie algebras.
