Abstract
We show that, in low dimensional conductors, the quasiparticle decay and the relaxation of the phase are not exponential processes. In quasi-one dimension, they scale as where the characteristic time , identical for both processes, is a power of the temperature. This result implies a distribution of relaxation times.
