Description
We present new constraints on the neutrino oscillation parameters , , and from a three-flavor analysis of solar and KamLAND data. The KamLAND data set includes data acquired following a radiopurity upgrade and amounts to a total exposure of target-proton-year. Under the assumption of invariance, a two-flavor analysis () of the KamLAND and solar data yields the best-fit values tan⁡2θ12=0.444-0.030+0.036 and ; a three-flavor analysis with as a free parameter yields the best-fit values tan⁡2θ12=0.452-0.033+0.035, , and sin⁡2θ13=0.020-0.016+0.016. This interval is consistent with other recent work combining the CHOOZ, atmospheric and long-baseline accelerator experiments. We also present a new global analysis, incorporating the CHOOZ, atmospheric, and accelerator data, which indicates sin⁡2θ13=0.009-0 …
