Class for defining a complex coefficient useful for extracting the CKM angle gamma from B -> D h h Dalitz plots.
Holds a set of real values that define the complex coefficient of an amplitude component. Depending on the type of the D decay, the amplitude has one of the following forms: CP-odd eigenstate: ( x + i * y ) * ( 1 - rB * exp( i * ( deltaB +/- gamma ) ) ) CP-even eigenstate: ( x + i * y ) * ( 1 + rB * exp( i * ( deltaB +/- gamma ) ) ) ADS favoured state: ( x + i * y ) * ( 1 + rB * rD * exp( i * ( deltaB - deltaD +/- gamma ) ) ) ADS suppressed state: ( x + i * y ) * ( rD * exp( - i * deltaD ) + rB * exp( i * ( deltaB +/- gamma ) ) ) [Phys. Rev. D79, 051301 (2009)]

Set the parameters based on the complex coefficients for particles and antiparticles.
This method is not supported by this class because there are more than four parameters, hence there is not a unique solution.
- Parameters
-
| [in] | coeff | the complex coefficient for a particle |
| [in] | coeffBar | the complex coefficient for an antiparticle |
| [in] | init | whether or not the initial and generated values should also be adjusted |
