Neutrino Issues Outline

Review slides by Peter Vogl and Maury Goodman for the 2008 PDG meeting regarding neutrino issues and future prospects. Discuss Chooz q13 limit, need for updated paradigm listings, and upcoming revisions. Evaluate implications and necessary updates for double beta decay section and neutrino mixing results. Explore parameter encoding challenges and non-standard interactions. Collaboration with theorists for addressing subtleties in notations.

Presentation Transcript

  1. Neutrino IssuesOutline • Review 3 slides that Peter Vogl and I sent to the 2008 PDG meeting • Discuss new “Chooz” q13 limit • Comment about need (?) for listings outside 3 n paradigm PDG meeting – n report Maury Goodman

  2. n - Looking Back • The 2006 revisions in the neutrino mixing sections added nodes on q’s and Dm2, and eliminated (many more) nodes on Probabilities of Oscillation. • This has been regarded as useful & successful Slide for 2008 PDG meeting from Maury Goodman & Petr Vogel PDG meeting – n report Maury Goodman

  3. n - Looking Forward-reviews • The listings state and assume Dm2atmoDm231Dm232 This is appropriate (for now). However there is a great deal of interesting physics at the next level, and the reviews allude to this in ways that aren’t totally consistent. They need to be carefully re-edited with this in mind. Not yet Slide for 2008 PDG meeting from Maury Goodman & Petr Vogel PDG meeting – n report Maury Goodman

  4. n - Looking Forward - Listings • The double beta decay section should be revised • Separating the 0n and 2n results • Hiding the excited states • As a result of the MiniBooNe results, the “Other Neutrino Mixing Results” section probably should be hidden in 2010. • We should be on the watch for what new nodes (if any) for new paradigms (>3n, etc.) partial No, darn it Not yet Slide for 2008 PDG meeting from Maury Goodman & Petr Vogel PDG meeting – n report Maury Goodman

  5. ∆m2 Palo Verde SK allowed sin22θ13 (90% CL) Chooz sin22θ13 New CHOOZ limithttp://pdglive.lbl.gov • CHOOZ limit curve has not changed • CHOOZ limit in 2008 PDG is: sin22θ13 < 0.19 You also see 0.10, 0.11, 0.14, 0.15, 0.20, … • PDG was at 2.0 10-3 eV2 based on 1s low Super-K Dm232 (best fit was in footnote) • For 2010 PDG, sin22θ13 < 0.15 based on MINOS best fitDm232=2.43 10-3 eV2 [1s low value (0.16) will be in footnote] PDG meeting – n report Maury Goodman

  6. Poster from PDG at Neutrino 2010 • Issues related to encoding q13 were presented at a poster, didn’t write paper PDG meeting – n report Maury Goodman

  7. Six PDG collaborators met at lunch at n2010 to discuss the issue of what else to encode: There was no strong desire to add anything, except maybe NSI At Nufact2010 I raised the issue again, and received a request to encode non-standard-interaction parameters Many measurements seek to test outside that paradigm n vs n 4 n 5 n Lorentz violation Sterile fractions Non standard Interactions … What is useful? Issue for PDGWhat to encode? PDG meeting – n report Maury Goodman

  8. NSI • I was referred to and in contact with theorist Sacha Davidson from Lyon who has agreed to help • One compendium of limits: • There are notation subtleties I haven’t absorbed yet. PDG meeting – n report Maury Goodman
