Minimal QCDF Model for Puzzle
Tsung-Wen Yeh
In this work, we propose a model by combining the parameterization method and the QCD factorization to study the puzzle. The parameterization introduces twelve parameters,…
to Form Factors in collinear factorization approach
Tsung-Wen Yeh
The form factors for semi-leptonic B decays, , are calculated under collinear factorization approach. The end-point divergences are regularized by a -regula…
Three Parton Corrections in decays
Tsung-Wen Yeh
The corrections from the three parton Fock state of the final state light meson in decays are evaluated by means of a collinear expansion method. The…
QCD factorization at twist-3: the two parton contributions
Tsung-Wen Yeh
In this paper, the twist-3 two parton corrections in charmless decays are shown to be factorizable under the QCD factorization approach. The factorizability of the twist-…
