Sensitivity to the KARMEN timing anomaly at MiniBooNE

Abstract

We present sensitivities for the MiniBooNE experiment to a rare exotic pion decay producing a massive particle Q 0 . This type of decay represents one possible explanation for the timing anomaly reported by the KARMEN Collaboration. MiniBooNE will be able to explore a region of the KARMEN signal that has not yet been investigated.

“…All protein molecular dynamics simulations were performed with the Amber7 suite of programs . Charges for novobiocin were generated from a RESP charge-fitting procedure with input from Hartree−Fock calculations at the 6-31G* level by use of the Gaussian03 program .…”

The high intensity frontier

“…A further indication of ¯ → ¯ e oscillations with a m 2 of 0.3-20 eV 2 comes from the beam dump LSND experiment detecting a 4 excess of ¯ e interactions in a neutrino beam produced by + decays at rest where the ¯ e component is strongly suppressed (∼7.8 × 10 −4 ) [69]. The KARMEN experiment [70], with a very similar technique but with a lower sensitivity (a factor 10 less for the lower m 2 ), and the NOMAD experiment at WANF of CERN SPS [71] (for m 2 > 10 eV 2 ) do not confirm the result, excluding a large part of the allowed region of the oscillation parameters. The LSND result doesn't fit the overall picture of neutrino oscillation and several non-standard explanations, for instance sterile neutrinos, have been put forward to solve this experimental conflict.…”

Neutrino beam design

“…The three neutrino oscillation scheme will result a bit more complicated, requiring nonstandard explanations, if the ν µ → ν e signal with |∆m 2 | of 0.3−20 eV 2 observed by LSND [18] will be confirmed by the MiniBooNE experiment at FNAL looking to ν µ → ν e transitions [19]. However a large part of the allowed region of the oscillation parameters was already excluded by KAR-MEN [20] experiment and NOMAD experiment at CERN SPS-WANF [21].…”
