title: Reunion of random walkers with a long range interaction: applications to polymers and quantum mechanics.
abstract: We use a renormalization group to calculate the reunion and survival exponents of a set of random walkers interacting with a long range 1/r2 and a short range interaction. These exponents are used to study the binding-unbinding transition of polymers and the behavior of several quantum problems.
