      abstract     = {With the start of the third programme-oriented funding
                      period (PoF-3) in 2015 the IKP has completed theprocess of
                      focusing its scientific portfolio to the two topics PANDA
                      and HESR at FAIR and storage ringEDM search (srEDM).After a
                      long period of uncertainty about the realizing of the FAIR
                      project, especially concerning the antiprotonpillar, the
                      FAIR council made a clear positive statement. All four
                      pillars of FAIR including the PANDAexperiment should be
                      completed simultaneously. That‘s a clear signal to go on
                      with the PANDA detectordevelopment and the HESR
                      preparations.The ongoing project srEDM promoted by the
                      international JEDI collaboration gained a high
                      scientificreputation as a potential flagship project in
                      basic research. Measurements or at least the extension of
                      thelimits of charged particle EDMs will try the limits of
                      the Standard Model and constrain models of supersymmetry.A
                      complementary project in the leptonic sector started
                      recently with the new IKP group of Prof. Ludhova,resulting
                      from the HGF recruiting initiative, for the study of
                      neutrino physics.The experimental activities at COSY have
                      changed from hadron physics to high precision spin
                      physicsand FAIR related component tests. About half of the
                      user beam time in 2015 was used for srEDM relatedstudies and
                      the other half was devoted to tests of HESR and FAIR
                      detector components.Apart from results originating from our
                      hadron physics activities at COSY the following
                      highlightshave been achieved in 2015:• FAIR: The
                      preparation of HESR is on schedule, first dipoles and
                      quadrupoles were delivered and thetest procedures have
                      started. Test measurements for the Straw Tube Tracker, the
                      MVD and the DAY-1KOALA experiment have been successfully
                      performed.• srEDM: A record long spin coherence time has
                      been achieved and various developments are on theway towards
                      the precursor experiment, like e.g. BPM, RF-Wien-filter, and
                      polarimeter. The precisionin the spin manipulation
                      techniques has reached such a high level that it provides a
                      diagnostics toolfor probing spin motion effects in storage
                      ring not accessible before.• Theory: The theory group
                      worked on various fields with exciting results. Examples are
                      first ab initiocalculations of alpha-alpha scattering, a
                      fundamental ingredient of the nucleosynthesis, the
                      precisedetermination of the pion-nucleon s-term or the
                      investigation of pentaquark-like structures and XYZstates.In
                      spite of the recognized high scientific value of our
                      research the board of directors suggested a transition ofthe
                      IKP after the contractual deliverables of the main
                      activities FAIR and srEDM within POF-3 are fulfilled.We are
                      convinced that curiosity-driven basic research, the main
                      topic at IKP is indispensable for a researchcenter with the
                      demand for a high scientific reputation. We believe that an
                      excellent approach for IKP orits future new structure will
                      be to keep the tripod of basic research with experiment,
                      theory and acceleratorscience. Presently the discussions
                      about the future of IKP are ongoing and there will be for
                      sure changes.Finally I would like to thank all IKP members,
                      the colleagues of the infrastructure departments andour
                      national and international collaboration partners for their
                      activities and support.},
