Abstract

We investigate the CP violating form factor of the ZZZ $an d$ ZZγ $v er t i ces in t h e p ai r p r o d u c t i o n o f$ Z^0 $b oso n s . U se f u l o b ser v ab l es ina z im u t ha l d i s t r ib u t i o n s a r eco n s t r u c t e d t o p r o b e$ CP $n o n co n ser v a t i o n w hi c hma y or i g ina t e f r o m t h ese v er t i ces . A s im pl e T w oH i g g s M o d e l o f$ CP$ violation is used as an illustration.
