IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University The LSND-ino (with help from Extra Dimensions) Tom Weiler Vanderbilt University
2
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University LSND data and inference Third m 2, and so fourth neutrino mass-state 4 Z-width requires 4 to be gauge-singlet – “sterile’
3
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Incredible, yes; Credible, ???? Fails S. Biller’s “redundancy criterion (and his second redundancy criterion too) Would I bet money on it being right? (I’d love to bet some of Don Perkin’s money on it, and WIN) Mini-BooNE coming very soon, to a conference near you.
4
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Failure of LSND stable sterile in 4D
5
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Proposed models (some dead) Three (or Four) Nu with broken CPT DEAD (ALIVE) Lepton-number violating muon decay DEAD Five Nu oscillations Low reheat-temperature cosmology QGravity decoherence with broken CPT MaVans (mass-varying neutrinos) Four Nu with decay Extra-dimensional geodesics for sterile neutrinos
6
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Have new parameters/new physics 5 th neutrino, DK to scalar, more spacetime, quantum gravity, new cosmology, coupling to DarkEnergy, ….. o Way beyond Standard Model o Testable predictions Commonality of models
7
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University KeV-MeV 4 model
8
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Fits Note the parameter equivalences
9
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Brane-Bulk resonance model
10
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University In QG/StringTheory, brane is dynamical, fluctuating due to Quantum Mechanics Thermal Mechanics In-Brane stresses (e.g. EM vs. gravity) Out of Brane experiences (e.g. trans-brane gravity)
11
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University A tale of two geodesics
12
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University BB-resonance which is the (fluctuation aspect ratio) 2
13
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Two-flavor resonances Define | a > U = | 4 > - | s >
14
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Brane-Bulk Resonant Oscillation In nu and nubar channels (gravity doesn’t care) CDHS
15
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Goodbye CDHS! CDHS
16
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Examples: n00 MeV resonance And significant disappearance for stopped-pion source (SNS)
17
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Example: 40 MeV resonance
18
IOP/CfCP Neutrino Meeting, June 29, 2005, Tom Weiler, Vanderbilt University Conclusions If LSND is correct, then …. theory needs a HUGE accommodation. (In)validation is “just around the corner, With Fermilab’s MiniBooNE experiment (altho some LSND models predict null MiniBooNE, positive something else)
