One-loop Neutron Electric Dipole Moment from Supersymmetry without R-parity

Y. -Y. Keum, Otto C. W. Kong

We present a detailed analysis together with exact numerical calculations on one-loop contributions to neutron electric dipole moment from supersymmetry without R-parity, focusing…

R-parity Violating Contribution to Neutron EDM at One-loop Order

Y. -Y. Keum, Otto C. W. Kong

We present the full result for the down squark mass-squared matrix in the complete theory of supersymmetry without R-parity where all kind of R-parity violating terms are admitted…

New Physics Search in B Meson Decays

Y. -Y. Keum

We discuss new physics search within the minimal supergravity model by using a possible large direct CP asymmetry in decays and B meson rare de…

A MODEL FOR THE CHARMED MESON DECAYS INTO THREE PIONS

M. GOURDIN, Y. Y. KEUM, X. Y. PHAM

We propose a phenomenological three component model describing the decay amplitude of the process $D_{s}^{+} \ra 3π$. The first component is a constant background, the second one i…

Factorization and SU(2) Heavy Flavor Symmetry for B-Meson Decays Producing Charmonium

M. Gourdin, Y. Y. Keum, X. Y. Pham

We show that the factorization assumption in color-suppressed meson decays is not ruled out by experimental data on $B \ra K(K^*) + J/Ψ(Ψ^{'})$. The problem previously pointed…

On the determination of the relative sign of and from polarization measurements in decay

Y. Y. Keum

We point out that polarization measurements such as the longitudinal fraction and the transverse left-right asymmetry in the Bauer-Stech-Wirbel (BSW) class III processes involving…
