Determining the CP-violating phase γ
TL;DR: In this paper, the authors show that non-CP eigenstates have a twofold advantage over CP eigenstate, i.e., the CP-violating phase γ, without any contamination from other weak phases.

Abstract: The weak phase γ is conventionally probed by theB
s→ρ
0 mode. The predicted rate is tiny. Even if aB
s→ρ
0
K
s rate difference could be established, it would not be clear that sin 2γ had been measured, because amplitudes with other weak phases may contribute significantly. Non-CP eigenstates, such asB
s
→D
±
K
∓, have a two-fold advantage overB
s→ρ
0
K
s. Their rates are orders of magnitude above that forB
s→ρ
0
K
s, and they probe theCP-violating phase γ, without any contamination from other weak phases. Detailed time-dependent studies of non-CP eigenstates remove possible final-state phases and extract the weak phase γ.

Universal unitarity triangle and physics beyond the standard model
Andrzej J. Buras,Paolo Gambino,Martin Gorbahn,Sebastian Jäger,Luca Silvestrini,Luca Silvestrini +5 more
TL;DR: In this paper, it was shown that there exists a universal unitarity triangle for all models, like the SM, the Two Higgs Doublet Models I and II and the MSSM with minimal flavour violation, that do not have any new operators beyond those present in the SM and in which all flavour changing transitions are governed by the CKM matrix.

Determining γ using B ± → DK ± with multibody D decays
TL;DR: In this paper, the authors proposed a method for determining the ε-gamma using only Cabibbo allowed D decays, and that large strong phases are expected due to the presence of resonances.

CP Violation in the Renormalizable Theory of Weak Interaction
TL;DR: In this article, it was shown that no CP-violating interactions exist in the quartet scheme without introducing any other new fields, and that the strong interaction must be chiral SU ( 4) X SU( 4) invariant as precisely as the conservation of the third component of the iso-spin.
