# B meson wave function in k(T) factorization

@article{Li2004BMW, title={B meson wave function in k(T) factorization}, author={Hsiang-nan Li and Huei-Shih Liao}, journal={Physical Review D}, year={2004}, volume={70}, pages={074030} }

We study the asymptotic behavior of the B meson wave function in the framework of k{sub T} factorization theorem. We first construct a definition of the k{sub T}-dependent B meson wave function, which is free of light-cone divergences. Next-to-leading-order corrections are then calculated based on this definition. The treatment of different types of logarithms in the above corrections, including the Sudakov logarithms, and those depending on a renormalization scale and on an infrared regulator…
