摘要：
A method to measure the structure of the weak charged-current in semileptonic b-hadron decays using the energy spectrum of the neutrinos is presented. This method allows to distinguish experimentally between the V-AxV-A, VxV-A and V+AxV-A form of the charged current interaction. First result of such a measurement have now been obtained by the L3 collaboration, a brief summary of their results is also given. Their results allow to exclude the exotic V+A structure in b-decays.
