Power corrections in the determination of heavy meson LCDAs: A renormalon-based estimation
Tu Guo, Chao Han, Wei Wang +1
At leading power accuracy the QCD light-cone distribution amplitudes (LCDAs) for a heavy meson can be matched onto the LCDAs in the framework of heavy-quark effective theory (HQET)…

Power corrections to quasi-distribution amplitudes of a heavy meson
Chao Han, Wei Wang, Jia-Lu Zhang +1
It has been recently demonstrated that lightcone distribution amplitudes (LCDAs) for a heavy meson, defined in the heavy quark limit, can be extracted by simulating quasi-distribut…
