Detailed Description

Class for defining a complex coefficient using the Belle CP convention. Holds a set of real values that define the complex coefficient of an amplitude component.

The amplitude has the form a * exp(i*delta) * ( 1 +/- b * exp(i*phi) ) where a is a CP conserving magnitude, b is a CP violating magnitude, delta is the strong phase and phi is the weak phase. [Phys.Rev.Lett. 96 (2006) 251803]
