摘要：
We derive, as the condition for the null vector decoupling, the fusion rules for the sl(2) algebra with fractional level, which have an interesting structure related to affine Weyl transformation. It is shown that, to get non-trivial fusion rules, we must include the primary field which belongs to neither the highest nor the lowest weight representations.
