An updated review on Kbar-N interactions is given within the theoretical framework of chiral SU(3) dynamics. The coupled-channels equations are solved with special emphasis on the constraints provided by the new kaonic hydrogen data from the SIDDHARTA measurements. Precision fits to K-p threshold and scattering data are performed and a new value of the complex K-p scattering length is deduced....

Giant nuclear systems of the form U+U, U+Cm, etc. can be formed with life-times from 10-19 sec. to 10-21 sec. These life-times depend on mass transfer and energy loss. In such systems the e+e- -vacuum is overcritical and spontanous decay sets in. Paul Kienle has contributed with pioneering experiments to understand and verify many of the effects connected with these fundamental...
