Statistical Analysis of the LSND and KARMEN numubar->nuebar Searches
A combined statistical analysis of the experimental results of the
LSND and KARMEN numubar -> nuebar oscillation search is presented. LSND has
evidence for neutrino oscillations that is not confirmed by the KARMEN
experiment. This joint analysis is based on the final likelihood
results for both data sets. A frequentist approach is applied to
deduce confidence regions. At a combined confidence level of 36 %,
there is no area of oscillation parameters compatible with both
experiments. For the complementary confidence of 1 - 0.36 = 64 %,
there are two well defined regions of oscillation parameters
sin^2(2theta), Delta m^2 compatible with both experiments.
