Theta^+ baryon production in KN and NN reactions

Yongseok Oh, Hungchong Kim, Su Houng Lee

We study $Θ^{+} (1540)$ productions in kaon-nucleon ( $K N$ ) and nucleon-nucleon ( $N N$ ) interactions by assuming that the $Θ^{+}$ is an isosinglet with $J^{P} = \frac{1}{2}^{+}$ . Possible $t$ -cha…

Spin asymmetries in gamma + N --> K*bar + Theta^+

Yongseok Oh, Hungchong Kim, Su Houng Lee

The photoproduction processes of the exotic $Θ^{+} (1540)$ baryon and the $K ˉ^{*}$ meson from the nucleon targets, i.e., $γ n \to K^{*-} Θ^{+}$ and $γ p \to K ˉ^{* 0} Θ^{+}$ , are inve…

Photon polarization in $B \to K_{res} γ$

Jong-Phil Lee

In this talk, I introduce recently proposed method for measuring the photon polarization in $B \to K_{res} γ$ . It is also shown that anomalous right-handed top couplings can seve…

Exotic Theta^+ baryon production induced by a photon and a pion

Yongseok Oh, Hungchong Kim, Su Houng Lee

We investigate the photoproduction of the $Θ^{+} (1540)$ on a nucleon ( $γ n \to K^{-} Θ^{+}$ , $γ p \to K ˉ^{0} Θ^{+}$ ) and the pion-induced $Θ^{+}$ production reaction on the proton ($π^- p \…

Probing the Radion-Higgs mixing at hadronic colliders

Kingman Cheung, C. S. Kim, Jeonghyeon Song

In the Randall-Sundrum model, the radion-Higgs mixing is weakly suppressed by the effective electroweak scale. One of its novel features would be a sizable three-point vertex of KK…

Are $Θ^{+}$ and the Roper resonance diquark-diquark-antiquark states?

R. D. Matheus, F. S. Navarra, M. Nielsen +2

We consider a $[u d]^{2} s ˉ$ current in the QCD sum rule framework to study the mass of the recently observed pentaquark state $Θ^{+} (1540)$ , obtaining good agreement with the exper…

Properties of baryon anti-decuplet

Yongseok Oh, Hungchong Kim, Su Houng Lee

We study the group structure of baryon anti-decuplet containing the $Θ^{+}$ . We derive the SU(3) mass relations among the pentaquark baryons in the anti-decuplet, when there is eithe…

$B\Bbar$ mixing with the bulk fields in the Randall-Sundrum model

Jong-Phil Lee

We calculate the $B\Bbar$ mixing in the Randall-Sundrum bulk model. In this model, all the Standard Model fields except the Higgs can reside in the bulk. Two suggestive models of "…

Photon polarization with anomalous right-handed top couplings in $B \to K_{r es} γ$

Jong-Phil Lee

The effect of anomalous right-handed top couplings on the photon polarization in $B \to K_{res} γ$ is investigated. It is recently reported that the photon polarization can be me…

Average Kinetic Energy of Heavy Quark ( $μ_{π}^{2}$ ) inside Heavy Meson of $0^{-}$ State by Bethe-Salpeter Method

C. S. Kim, Guo-Li Wang

The average kinetic energy of the heavy quark inside $B$ or $D$ meson is computed by means of the instantaneous Bethe-Salpeter method. We first solve the relativistic Salpeter equa…

Higher meson resonances in $ρ \to π^{0} π^{0} γ$ and $ω \to π^{0} π^{0} γ$

Yongseok Oh, Hungchong Kim

The role of higher meson resonances with spin 1 and 2 is investigated quantitatively in the decay processes of $ρ \to π^{0} π^{0} γ$ and $ω \to π^{0} π^{0} γ$ . Among the higher resonances, we…

Remarks on the recently observed B decays into $f_{X} (1300) K$ and $J / ψ K_{X}^{*} (1430)$

C. S. Kim, Sechul Oh

In light of the recent experimental results on decays $B^{+} \to f_{X} (1300) K^{+}$ and $B^{\pm (0)} \to J / ψ K_{X}^{*\pm (0)} (1430)$ from Belle, we study the $B \to P (V) S$ type decays, $B^{\…

Heavy Baryonic Decays of Λ_b \to Λη^{(\prime)} and Nonspectator Contribution

M. R. Ahmady, C. S. Kim, Sechul Oh +1

We calculate the branching ratios of the hadronic Λ_b decays to ηand η^\prime in the factorization approximation where the form factors are estimated via QCD sum rules and the pole…

B -> eta^(\prime) l nu decays and the flavor-singlet form factor

C. S. Kim, Sechul Oh, Chaehyun Yu

We study semileptonic decays B -> eta^(\prime) l nu, taking into account the flavor-singlet contribution (F^{singlet}_+) to the B -> eta^(\prime) form factors, which arises from th…
