Heavy Majorana neutrinos in e+e- colliders

G. Cvetic, C. S. Kim, C. W. Kim

We investigate possibilities for detecting heavy Majorana neutrinos ( $N$ 's) in $e^{+} e^{-}$ at LEP200 and future Linear Colliders. We concentrate on the processes where the pairs of in…

Bi-maximal Lepton Flavor Mixing Matrix and Neutrino Oscillation

Sin Kyu Kang, C. S. Kim

Recently, many authors showed that if the solar and atmospheric neutrino data are both described by maximal mixing vacuum oscillations at the relevant mass scale, then there exists…

Signals for CP-Violation in Scalar Tau Pair Production at Muon Colliders

Seong-Youl Choi, Manuel Drees

We discuss signals for CP-violation in $μ^{+} μ^{-} \to τ ~_{i}^{-} τ ~_{j}^{+}$ , where $i, j = 1, 2$ label the two scalar $τ$ mass eigenstates. We assume that these reactions can proc…

A Model Independent Analysis of the Rare B Decay B -> X_s l^+ l^-

S. Fukae, C. S. Kim, T. Morozumi +1

The most general model-independent analysis of the rare $B$ decay, $\Bsll$, is presented. There are ten independent local four-Fermi interactions which may contribute to this proce…

CP-Violation through Scalar Tau Oscillation

Seong-Youl Choi, Manuel Drees

We point out that oscillation between the two scalar tau (stau) mass eigenstates can give rise to CP-violation if some parameters appearing in the stau or chargino/neutralino mass…

Higgs-mediated flavor-changing neutral currents in the general framework with two Higgs doublets -- an RGE analysis

G. Cvetic, C. S. Kim, S. S. Hwang

We consider the standard model with two Higgs doublets with the most general Yukawa coupling terms (``type III''). In the model, the neutral-Higgs-mediated flavor-changing neutral…

CP Violation in the Cabbibo-suppressed Decay Tau->K Pi Nu_tau with Polarized Tau Leptons

S. Y. Choi, Jake Lee, J. Song

CP violation from physics beyond the Standard Model (SM) is investigated in the Cabbibo-suppressed decay $τ \to K π ν_{τ}$ with polarized $τ$ leptons, to which both the ${\rm J}^{P}=1^-…

Exclusive B --> M l^+ l^- (M=π, K, ρ, K^*) Decays and Determinations of |V_{ts}| (and |V_{td}/V_{ts}|)

T. M. Aliev, C. S. Kim, M. Savci

We examine the possibility for precise determination of |V_{ts}| (and |V_{td}/V_{ts}|) from the exclusive decays, $B - - > K ℓ^{+} ℓ^{-}, B - - > K^{*} ℓ^{+} ℓ^{-}$ (and $B --> π\ell…
