The goal of this project is the detailed investigation of hadronic matrix elements relevant for exclusive b-decays. This includes mesonic and baryonic transition form factors which will be calculated in the framework of QCD light-cone sum rules. Moreover, we will improve our understanding of light-cone distribution amplitudes for light and heavy hadrons on the basis of model-independent parameterisations. In this way, we will increase the precision of the theoretical predictions for various heavy hadron decays.

这个项目的目标是详细调查强子矩阵元素相关的排他性b衰变。这包括将在QCD光锥求和规则的框架中计算的介子和重子跃迁形式因子。此外，我们将在与模型无关的参数化的基础上提高我们对轻强子和重强子的光锥分布振幅的理解。这样，我们将提高各种重强子衰变理论预测的精度。
