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…

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…

The mass of charmonium in nuclear matter

Su Houng Lee

The masses of charmonium states immersed in nuclear matter are calculated in LO QCD and in QCD sum rules. While the mass shift for $J / ψ$ are found to be less than -10 MeV, those fo…
