Possible supersymmetric solution to the discrepancy between B-->phiK(S) and B-->eta'K(S) CP asymmetries

Area of Science:

• High Energy Physics
• Particle Physics
• Supersymmetry

Background:

• Observed discrepancies exist in the mixing CP asymmetries of B-->phiK(S) and B-->eta(')K(S) decays.
• These discrepancies challenge the Standard Model of particle physics.
• The large branching ratio of B-->eta'K decays presents a separate puzzle.

Purpose of the Study:

• To propose a supersymmetric solution for the observed CP asymmetry discrepancies in B meson decays.
• To investigate the impact of R-sector supersymmetric contributions on these asymmetries.
• To analyze the effect of proposed mechanisms for the B-->eta'K branching ratio on S(eta(')K(S)).

Main Methods:

• Theoretical modeling of supersymmetric contributions to B meson decays.
• Analysis of CP asymmetries in B-->phiK(S) and B-->eta(')K(S) within a supersymmetric framework.
• Inclusion of R-sector contributions and their sign differences based on final state parity.

Main Results:

• Supersymmetric contributions from the R sector exhibit opposite signs for B-->phiK(S) and B-->eta(')K(S) due to differing final state parities.
• This sign difference naturally explains why S(phiK(S)) is not equal to S(eta(')K(S)).
• The study considers the influence of mechanisms addressing the B-->eta'K branching ratio puzzle on S(eta(')K(S)).

Conclusions:

• A supersymmetric solution is proposed for the CP asymmetry discrepancies in B meson decays.
• The model successfully accounts for the observed differences by leveraging parity in final states.
• Further investigation into proposed mechanisms for B-->eta'K is warranted within this framework.
