non-zero  1 3 vs FC-NSI in the solar neutrino sector Existing analyses show a weak preference ( sigma) for non-zero  13 in the (Solar + KamLAND) analysis. Comes from sol-KL “clash” A similar hint is found in some atm analyses. A weak preference also evidenced in the MINOS data in the  -> e appearance channel Though very weak note that solar transitions are dominated by matter effects, while the oscillations seen in KamLAND occur in the earth crust, where matter effects are negligible. What if nsi are present? JV5

Impact of FC NSI We expect a degeneracy between  13 and FC … 1,2 sigma positive nsi values shift LMA towards bigger  12 alleviating the tension with KamLAND, the same way as a non-zero  13 A.

PROBE HIGH FROM LOW SCALE 0RIGIN OF NEUTRINO MASS - via NSI strength novel neutrino propagation effects beyond oscillations + LFV effects in charged sector & new states at LHC STILL DO NOT UNDERSTAND FLAVOR - flavor models correlate LFV phenomena - if linked to unification, hard to reconcile L- & Q-mixings OSCILLATIONS MAINLY ROBUST but NEED NON-OSCILLATION TESTS: B&DBD, COSMO & ASTRO SK-atmospheric and MINOS (appearance) data analysis may help to break degeneracy between  13 and FC NSI. Future reactors (Double-CHOOZ, Daya-Bay, RENO) will give a “clean” measure of  13, unaffected by NSI effects. non-confirmation of current  13 hints + persisting tension between solar and KamLAND would pose a new problem in the “solar sector” which might require NSI or other possible unaccounted effects JV19
