New QCD Sum Rule for $D (0^{+})$

Yuan-Ben Dai, Shi-Lin Zhu

We derive a new QCD sum rule for $D (0^{+})$ which has only the $D π$ continuum with a resonance in the hadron side, using the assumption similar to that has been successfully used in…

Contribution of $D K$ Continuum in the QCD Sum Rule for $D_{s J} (2317)$

Yuan-Ben Dai, Xin-Qiang Li, Shi-Lin Zhu +1

Using the soft-pion theorem and the assumption on the final-state interactions, we include the contribution of $D K$ continuum into the QCD sum rules for $D_{s J} (2317)$ meson. We fi…

Exclusive Semileptonic Rare Decays $B \to K^{(*)} l^{+} l^{-}$ in a SUSY SO(10) GUT

Wen-Jun Li, Yuan-Ben Dai, Chao-Shang Huang

In the SUSY SO(10) GUT context, we study the exclusive processes $B \to K^{(*)} l^{+} l^{-} (l = μ, τ)$ . Using the Wilson coefficients of relevant operators including the new operators $Q_{…

Possible Interpretations of $D_{s J}^{+} (2632)$ If It Really Exists

Yuan-Ben Dai, Chun Liu, Y. -R. Liu +1

We analyze various possible interpretations of the narrow state $D_{s J}^{+} (2632)$ observed by SELEX Collaboration recently, which lies above threshold and has abnormal decay pattern…

D_s(2317) and D_s(2457) from HQET Sum Rules

Yuan-Ben Dai, Chao-Shang Huang, Chun Liu +1

Within the framework of the heavy quark effective theory, QCD sum rules are used to calculate the masses of p-wave (c-bar s) states. The results for 0^+ and 1^+ states with the ang…

Understanding the $D_{s J}^{+} (2317)$ and $D_{s J}^{+} (2460)$ with Sum Rules in HQET

Yuan-Ben Dai, Chao-Shang Huang, Chun Liu +1

In the framework of heavy quark effective theory we use QCD sum rules to calculate the masses of the $c ˉ s$ $(0^{+}, 1^{+})$ and $(1^{+}, 2^{+})$ excited states. The results are consis…
