15 Jul 2002 | | Journal: | Phys.Rev. D66 (2002) 076007 | | Subject: | hep-ph hep-ex hep-lat | | Affiliation: | Mainz U.), Chun Liu (Mainz U., and ITP, Beijing), Chi-Tau Yan (ITP, Beijing | | Abstract: | The B --> pi ell nu weak decay form factors are calculated via light-cone sum rules within the framework of the heavy quark effective theory. We calculate the leading and the relevant sub-leading universal form factors. Our results are matched to the known soft pion limit. We also address the large pion energy limit of our sum rule results. Our results are compared with that of other approaches. | | Source: | arXiv, hep-ph/0207179 | | Services: | Forum | Review | PDF | Favorites | |
