The scientific work of IKP-2 focuses on the topics "Precision experiments with polarized particles".

A central project here is the search for permanent electric dipole moments (EDM) of charged hadrons (JEDI), which - if they exist - can provide an answer to the question why the universe today contains almost exclusively matter, although according to current understanding matter and antimatter were created in equal amounts shortly after the Big Bang.

Furthermore, polarised particles produced in polarised targets or polarised ion sources are investigated.

In the course of the transition of the IKP from the research centre to the GSI, the neutrino physics group of Prof. Dr. Livia Ludhova previously assigned to the IKP-2 was relocated to the University of Mainz.

The former hadron physics experiments at the internal detector systems ANKE und WASA have been finished successfully at the end of the previous funding period. Individual data analysis projects are still underway. The scientific results concerning hadron physics at COSY have been summarized in an review article.

Electric Dipole Moments

The JEDI (Jülich Electric Dipole moment Investigations) collaboration was created in the end of 2011. It is aiming to carry out a long term project for the measurement of permanent electic dipole moments of charged particles in storage rings. The picture on the left shows the RF (radio frequency) Wien filter, which will be used for first measurement at COSY, installed in the COSY ring.

Polarized Particles and Possible Applications

The progress of polarized beams and targets for accelerators and the corresponding techniques opens the door to new applications in different fields. Thus, further developments like polarized targets for laser acceleration or nuclear-polarized H<sub>2</sub>+/D2+ ions as polarized beam for future accelerators are underway. As next polarized fuel for fusion reactors or new types of precision spectroscopy for atoms are possible.
