Invariant approach to <i>CP</i> in unbroken Δ(27)
The invariant approach is a powerful method for studying <i>CP</i> violation for specific Lagrangians. The method is particularly useful for dealing with discrete family symmetries. We focus on the <i>CP</i> properties of unbroken Δ(27) invariant Lagrangians with Yukawa-like...

| 520 | |a The invariant approach is a powerful method for studying <i>CP</i> violation for specific Lagrangians. The method is particularly useful for dealing with discrete family symmetries. We focus on the <i>CP</i> properties of unbroken Δ(27) invariant Lagrangians with Yukawa-like terms, which proves to be a rich framework, with distinct aspects of <i>CP</i>, making it an ideal group to investigate with the invariant approach. We classify Lagrangians depending on the number of fields transforming as irreducible triplet representations of Δ(27). For each case, we construct <i>CP</i>-odd weak basis invariants and use them to discuss the respective <i>CP</i> properties. We find that <i>CP</i> violation is sensitive to the number and type of Δ(27) representations. | ||
