The angle beta / phi1

This meeting will discuss the published papers from BaBar and Belle related to B-factories, including topics such as J/psi.K*, D(*)D(*), D(*)h0, and more. It will also cover future prospects and limitations in experimental methods and interpretation.

  1. The angle beta / phi1 Section Editors BaBar: Owen Long Belle: Yoshihide Sakai Theory: to be determined… B-factories Legacy Book Meeting SLAC, Oct 30-31

  2. Papers BaBar Published Main ccbars, 465 MBB: PRD 79, 072009 J/psi K* cos2, 88 MBB: PRD 71, 032005 3) J/psi 0, 465 MBB: PRL 101, 021801 4) D(*)D(*), 465 MBB: PRD 79, 032002 5) D(*)h0, 383 MBB: PRL 99, 231802 6) , full reco, 232 MBB: PRD 73, 111101 7) , partial reco, 232 MBB: PRD 71, 112003 8) ’K,K,0K, 465 MBB: PRD 79, 052003 9) K+K-K0, 465 MBB: arXiv:0808.0700 (prelim) 10) -K0, 383 MBB: arXiv:0905.3615 (PRD) 11) K0, 232 MBB: PRD 76, 071101 Foreseen papers in time to be included in the book: BaBar hopes to update  measurements, J/psiK* TD angular analysis (cos2), and several 3-body penguin modes with full DS. Belle Published 1) Reference 2) ... Foreseen papers in time to be included in the book : 1) Belle plans to update most of the important modes to full dataset. Summary of papers (BaBar+Belle): 1) PRL: 2+? 2) PRD: 9+? 3) ....

  3. Section subdivision • For each subsection • CKM context for measurement. How it fits into bigger picture. (0.5 - 1.0 p) • Experimental methods (1 - 2 p) • Results including experimental limitations. (0.5 p) • Interpretation including theoretical limitations. (0.5 - 1.0 p) • Future prospects (here or all together at the end?) (0.5 p) • Typical subsection page count: 3 - 5 p. 1) Intro/overview 2) ccbars (J/psi K0, …) 3) ccbard (J/psi 0, DDbar) 4) cubard (D0h0) 5) Charmless qqbars a) Q2b b) 3-body, non-Dalitz c) 3-body, Dalitz 6) Review of methods to break discrete ambiguity (J/psiK*, 3K, …). 7) sin() 8) Future prospects (at LHCB and Super B factories) 9) Summary Approximate expected # pages needed for whole section: 24 - 40 p

  4. Inter-correlation All: Should we have a section on TDCPV analysis (general S and C measurement) in the tools and methods? This would be helpful for beta and alpha. Tag-side interference: Where does this go? In tagging section? Or (new) TDCPV analysis section? : Related to gamma section, though fits better in beta (It’s TDCPV not direct CPV). Charmless qqbars: Event selection and background suppression related to charmless B decays sec. Resolution: refer to charmless B decays section for details on these methods. Charmless qqbars, Dalitz analysis Point to Dalitz analysis section for generalities. J/psiK* TD angular analysis Should we have section on angular analysis of B->VV in the tools and methods?

  5. Contributors Confirmed (beside section editors) BaBar: Max Baak ( full reco, tag-side interference) Eli Ben Haim (charmless 3-body) Adrian Bevan (J/psi 0, advise on main ccbars) Chunhui Chen (ccbars, DDbar, …) Chih-hsiang Cheng (ccbars, D0h0, …) Alfio Lazzaro (charmless Q2b) Abi Soffer ( partial reco) Belle: TBA Un-confirmed BaBar: # Belle: #

  6. Comments Still very early in the organization.
