3. What was the goal of the International Meeting ? –Involve world-wide project leaders and agency responsibles to set-up instruments for the encouragement and follow-up of global convergence. –In particular it needed to ● Assess the physics case once more, let the mutual criticisms express themselves ● Assess the perimeter of the things to coordinate ● Construct a single “agency ear” as a support for the efforts of the global neutrino community to coordinate ● Optimise in parallel the agency coordination, learning lessons from previous efforts (eg FALC and ILC) –It had good timing (CERN approval of Medium-term plan, P5 and HEPAP statements, Japanese roadmap). As planned.

4. ● “ THE PRESS RELEASE ● “Neutrino physics enters the global era” ● The agencies and laboratory directors gathered at the International Meeting on Large Neutrino Infrastructures agreed that the understanding of the neutrino sector is a worldwide priority promising physics beyond the Standard Model in a unified theoretical framework that goes from the Electroweak Scale to the highest energy scales. Furthermore, this program is complementary to neutrino related measurements made in cosmology and provides crucial input to the knowledge of the Universe. ● They further examined the neutrino program developing internationally relating to experiments using accelerator beams, reactors, cosmic rays and underground laboratories. They were pleased with the first efforts of coordination of the neutrino community in the above domains. ●Agencies (in alphabetical order): J. Siegrist (DOE) J.Martino (IN2P3/CNRS), A. Masiero ( INFN), H. Tanaka (NSERC), J. Womersley (STFC) and G.Patry (CEO of the Canada Foundation of Innovation, CFI) also participated as an observer. ●Directors of laboratory (in alphabetical order): S.Bertolucci (CERN), N. Lockyer (Fermilab), Y. Wang (IHEP) N. Mondal (INO), P. Chomaz (IRFU/DSM/CEA) Y. Okada (KEK) F. Piquemal ( LSM) and N. Smith (SNOLAB). ●Also Neutrino ICFA panel (K. Long + many other members) ● Also HEPAP/P5 (A. Lankford, S. Ritz) 4

5. I. Concerning the first domain, they welcome the recent approval by the CERN council of the medium-term CERN plan, consistent with the European Strategy document, including the hosting of a neutrino platform at CERN for R&D and prototyping for the next generation of neutrino detectors, as the main CERN investment to the development of a worldwide program. II. They also welcome the proposed upgrade of the J-PARC beam and the proposal to construct Hyper-Kamiokande, a megaton scale water Cherenkov detector with large international participation in Kamioka. These upgrades are clearly the continuation of Japan’s tradition of maintaining a leading neutrino program. III. They support the vision of the HEPAP/P5 report to host an international facility for short and long-baseline neutrino oscillations at Fermilab, where internationally driven collaborations are encouraged to propose a program optimised in baseline and detector technology. This approach, in parallel with the decision of Fermilab to upgrade its beam infrastructure (PIP-II) gives the opportunity for a rich international neutrino program at Fermilab. 5 The main statement I (opportunities)

6. ● The agencies and laboratory directors invite the neutrino scientific community to develop urgently a coherent international program which exploits the above opportunities. ● They will meet again in early 2015 in the U.S.A, to evaluate the progress made with respect to this goal. 6 The main statement II ( recommendations and follow-up)

7. Furthermore, ● the situation concerning the "neutrino anomalies" needs to be clarified. This will be addressed by the neutrino short baseline program mentioned above and by smaller scale endeavours putting neutrino sources near the detector. ● In the reactor related domain, there are currently two large projects in development in Asia. The approved JUNO experiment located in China, whose goal is to determine the mass hierarchy by using reactor neutrinos while also performing precision measurement of oscillation parameters, studies of supernova neutrinos, geo-neutrinos, solar and atmospheric neutrinos. The JUNO proto-collaboration welcomes more international participation. In parallel, the RENO-50 proposal, with quite similar characteristics, is under evaluation in Korea. ● The neutrino mass hierarchy and sinθ 23 octant will also be measured through atmospheric neutrinos a) in INO, a 50 kton magnetized iron detector in India, that will start deployment in a few years, calling for international participation to increase its size to 100 kton to address the mass hierarchy problem on a shorter time scale, b) through the proposed upgrades of the neutrino observatory ICECUBE (PINGU) and the projected KM3Net (ORCA). 7 Neutrino sector is not only LBL (I)

8. ● Last but not least, there is a rich physics program in development both for single beta and neutrino-less double beta decay measurements currently probing the quasi-degenerate region of neutrino masses. The next ambitious goal for double-beta decay is the coverage in sensitivity of the inverted mass- hierarchy region; achieving this goal will require large enrichment of isotopes and ton scale detectors, boosting the scale of the experiments and therefore demanding international collaborations for their construction. ● The agencies urge the underground laboratory directors to prepare the ground for an international evaluation in 2-3 years time leading to a selection of the most promising technologies for the next generation detectors worldwide. ● While the agencies and the laboratory directors recognise that to realise the success of the above projects there will be a need for investment in theory and necessary support measurements, this document should not be interpreted as a funding endorsement. ● Finally, the agencies and the laboratory directors will seek the advice of the Neutrino ICFA panel as well as the IUPAP working group of Astroparticle Physics International Committee (APPIC) on all the above issues. 8 Neutrino sector is not only LBL (II)

9. ● A new form of global coordination is attempted around the issues of the neutrino sector ● First appointment the Long Baseline issue ● The agencies are decided to meet frequently in an “ad hoc “ format (every 6 months) to examine the progress – APPEC is discussing with EU for a funding of the logistics of this global coordination (project officer, meeting and workshop support, eventual common R&D calls, other issues of coordination) ● In parallel, other neutrino topics also need coordination, e.g. neutrinoless double beta decay ● Towards a final decision in many topics in a horizon of 2-3 years time ? What’s next ?
