Philip Lüghausen: Systematic Parametrisation and Operator Product Expansion for the $B_q$-meson Light-Cone Distribution Amplitude




Abstract:  In this talk, we discuss the B-meson Light-Cone Distribution Amplitude (LCDA), which is an important input to B-physics phenomenology. We review the status of its Operator Product Expansion (OPE) and introduce a new, systematic approach to its parametrization. We discuss how these techniques can be effectively used together. Finally, we provide results for the OPE calculation for a non-zero spectator mass.
