Abstract
Two one-dimensional Luttinger liquid systems coupled by Hund coupling are studied by the renormalization-group and non-Abelian bosonization methods. It is found that the Hund coupling is always relevant irrespective of the repulsive interaction between electrons within each chain. The properties of the resulting strong coupling fixed point are discussed.
