QCD sum rules for the anti-charmed pentaquark
Yasemin Sarac, Hungchong Kim, Su Houng Lee
We present a QCD sum rule analysis for the anti-charmed pentaquark state with and without strangeness. While the sum rules for most of the currents are either non-convergent or dom…
Anti-charmed pentaquark from B decays
Su Houng Lee, Youngshin Kwon, Youngjoon Kwon
We explore the possibility of observing the anti-charmed pentaquark state from the decay of meson produced at -factory experiments. We first show that the…
Non-interacting KN contribution in the QCD sum rule for the pentaquark Theta^+(1540)
Youngshin Kwon, Atsushi Hosaka, Su Houng Lee
We perform a QCD sum rule analysis for the pentaquark baryon Theta^+ with the non-interacting contribution treated carefully. The coupling of the Theta^+ current to the s…
Quarkonium-Hadron Interactions in Perturbative QCD
Taesoo Song, Su Houng Lee
The next to leading order (NLO) quarkonium-hadron cross section is calculated in perturbative QCD. The corresponding leading order (LO) result was performed by Peskin more than 20…
