Abstract
Motivated by the heavy-flavor experiments at running Large Hadron Collider (LHC) and upgrading SuperKEKB, which provide abundant [Formula: see text] data samples, the tree-dominated [Formula: see text] and [Formula: see text] (n =1, 2, 3) weak decays are studied within the framework of quantum chromodynamics (QCD) factorization. The QCD corrections to the longitudinal and transverse amplitudes are evaluated at next-to-leading order, and the branching fractions and polarization fractions are predicted. Numerically, the [Formula: see text] decays have relatively large branching fractions at the order of [Formula: see text] and are in the scope of the LHC and SuperKEKB/Belle-II experiments.
