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…
Lightcone and quasi distribution amplitudes for light octet and decuplet baryons
Chao Han, Wei Wang, Jun Zeng +1
We present a comprehensive investigation of leading-twist lightcone distribution amplitudes (LCDAs) and quasi distribution amplitudes (quasi-DAs) for light octet and decuplet baryo…
Light baryon spatial correlators at short distances
Chao Han, Jialu Zhang
To study the light baryon light-cone distribution amplitudes (LCDAs), the spatial correlator of the light baryon has been calculated up to one-loop order in coordinate space. They…
