Vxb Workshop


This workshop aimes to bring together theorists and experimentalists working on the extraction of Vub, Vcb and related quantities with the focus on understanding the involved uncertainties. Physics topics covered by this include:

  • b --> u l nu (incl.)
  • b --> u l nu (excl.)
  • b --> s gamma
  • b --> c l nu (incl.)
  • b --> c l nu (excl.)


The sessions will consist of few presentations with a lot of room for discussions. The material presented should not be quoted outside the workshop without the consent of the respective author.

Christian Bauer has kindly agreed to give a SLAC seminar on Thursday, December 6th at 12:30 pm in the Panofsky Auditorium on Vub and Vcb and this will serve as an introduction to the workshop.

Everybody is invited to prepare one or two slides as contribution to the discussion part in each session. Talks will be posted to the BaBar internal web which is accessible by BaBar members only. The format should be .pdf and/or .ps.gz. External participants are encouraged to provide:

  1. CD-ROM with .pdf or .ps or .ps.gz file
  2. or external URI with .pdf or .ps or .ps.gz file
  3. or MS-DOS formated floppy disk with .pdf or .ps or .ps.gz file
  4. or just the transparencies and we'll scan them

The material should be provided in advance so that we have time to arrange for scanning/copying of the files. In case of option 2 (URI) please send the URI to

The public presentations are accessible here,
all of the presentations (with the BABAR internal) are accessible here.


In order to participate a registration is required here.
