Based on the notion that the local dark-matter field of axions or axionlike particles (ALPs) in our Galaxy induces oscillating couplings to the spins of nucleons and nuclei (via the electric dipole moment of the latter and/or the paramagnetic axion-w

In a previous publication, measurements of the depolarization of a stored proton beam by interaction with a co-propagating unpolarized electron beam at low relative energy have been presented and an upper limit of about 3 x 10(7) b for the electron-p

The deuteron tensor analysing power t_{20} of the d(pol) p --> 3He eta reaction has been measured at the COSY-ANKE facility in small steps in excess energy Q up to Q = 11 MeV. Despite the square of the production amplitude varying by over a factor of

In order to understand experimental data for K+ production in proton-deuteron interactions and draw conclusions about the ratio between K+ production in pn and pp, one needs to develop an approach for the description of all relevant pp results. We pe

The differential cross section for the exclusive dp -> 3He{\pi}+{\pi}- reaction has been measured with high resolution and large statistics over a large fraction of the backward 3He hemisphere at the excess energy 265 MeV using the COSY-ANKE magnetic

The K+-production cross section in pn collisions is an important input parameter for model calculations of K+ production in proton-nucleus and nucleus-nucleus interactions. Experimental data in the close-to-threshold region are not yet available and

The production of omega-mesons in the pp->pp omega reaction has been investigated with the COSY-ANKE spectrometer for excess energies of 60 and 92MeV by detecting the two final protons and reconstructing their missing mass. The large multipion backgr
