Invisible decays of vector Charmonia and Bottomonia to determine the Weak Mixing Angle at quarkonia scale

G. Hernández-Tomé, C. S. Kim, G. López Castro

We compute the branching fractions of vector quarkonia ( $V_{Q} = J / ψ, ψ^{'}, Υ (n S)$ ) decays into neutrino pairs, considering both Dirac and Majorana types, within the Standard Model (SM)…

Rare tau decays via exchange of on-shell almost degenerate Majorana neutrinos, $τ^{\mp} \to π^{\mp} N_{j} \to π^{\mp} μ^{\mp} π^{\pm}$ and $τ^{\mp} \to π^{\mp} N_{j} \to π^{\mp} μ^{\pm} π^{\mp}$

Gorazd Cvetic, C. S. Kim

We investigate rare decays of tau leptons that occur via exchange of heavy on-shell neutrinos $N_{j}$ ( $j = 1, 2$ ). These neutrinos can be either Dirac or Majorana, and are considered t…

Sensitivity bounds on heavy neutrino mixing $∣ U_{μ N} ∣^{2}$ and $∣ U_{τ N} ∣^{2}$ from LHCb upgrade

Gorazd Cvetic, C. S. Kim

Decays of heavy pseudoscalar mesons $B$ , $B_{c}$ , $B_{s}$ and $D_{s}$ at LHCb upgrade are considered, which produce either two equal sign muons or taus. In addition, we consider the anal…

Sensitivity limits on heavy-light mixing $∣ U_{μ N} ∣^{2}$ from lepton number violating $B$ meson decays

Gorazd Cvetic, C. S. Kim

We consider the lepton number violating decays $B \to μ^{\pm} μ^{\pm} π^{\mp}$ and $B \to D^{(*)} μ^{\pm} μ^{\pm} π^{\mp}$ which may be detected at LHCb and Belle-II experiments; a…

Heavy Majorana neutrino production at electron-muon colliders

G. Cvetic, C. S. Kim

Possibilities for detecting heavy Majorana neutrinos ( $N$ 's) at future $e μ$ colliders are investigated. In contrast to the $e^{-} e^{+}$ colliders (LEP200 and NLC), the center-of-mass (…

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…

CP Violation in the Semileptonic $B_{l 4}$ ( $B - > D π l ν$ ) Decays: Multi-Higgs Doublet Model and Scalar-Leptoquark Models

C. S. Kim, Jake Lee, W. Namgung

CP violation from physics beyond the Standard Model is investigated in $B_{l 4}$ decays: $B \to D π l ν ˉ_{l}$ . In the decay process, we include various excited states as intermediate s…

One-loop renormalization group equations of the general framework with two Higgs doublets

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

We derive one-loop renormalization group equations (RGE's) for Yukawa coupling parameters of quarks and for the vacuum expectation values of the Higgs doublets in a general framewo…

Color-Octet Contributions in the Associate J/psi+gamma Hadroproduction

C. S. Kim, Jungil Lee, H. S. Song

Color-octet contributions to the associate J/psi+gamma hadroproduction are studied in detail, and found to be negligible, compared to the ordinary color-singlet contribution. Withi…

Quark-Lepton Flavor Democracy and the Non-Existence of the Fourth Generation

G. Cvetic, C. S. Kim

In the Standard Model with two Higgs doublets (type II), which has a consistent trend to a flavor gauge theory and its related flavor democracy in the quark and the leptonic sector…
