J. Rohrwild

摘要:

利用光锥QCD求和规则研究了实光子点$Q^2=0$处的辐射$Δ\to γN$跃迁。特别是,我们确定的总和规则的过渡形状因子$G_M(0)$和$R_{EM}$扭转4。

英文摘要:

The radiative $Δ\to γN$ transition is examined at the real photon point $Q^2=0$ using the framework of light-cone QCD sum rules. In particular, we determine the sum rules for the transition form factors $G_M(0)$ and $R_{EM}$ up to twist 4.
