In memory of Carl B. Dover Carl Dover was a leading figure in Hadronic Nuclear Physics over the last two decades, particularly in Strangeness Nuclear Physics, a subject with which most of this Volume deals, but notably also in Antinucleon Physics. The attached Curriculum Vitae and List of Publications demonstrate beyond any doubt the breadth of his scientific activity. Dover's scientific work hinged on pushing the frontiers of phenomenology into unknown domains. Thus, as soon as the study of A hypernuclei using the (K-, 7r-) reaction was established at CERN and Brookhaven during the late 70s, and while still analyzing together with colleagues at Brookhaven the information content of these experiments, Dover in a seminal paper together with Ludeking and Walker proposed using the (Tr+,K +) reaction to study novel types of states in hypernuclei. It is due to this idea, expanded later on by Bando and Motoba in Japan and successfully applied at Brookhaven and KEK, that our modern arsenal of A hypernuclear formation, spectroscopic and decay data has substantially grown up and diversified. It was his foresight that led him in 1988, together with Millener and Gal, to show how the first Brookhaven AGS data of (~r +, K +) excitation spectra over the periodic table are underlied by perhaps the neatest example of single-particle structure in nuclear physics, and to extract the corresponding mean field experienced by the A hyperon.
Dover was also a pioneer to work out in sufficient detail how to use skillfully the (K-, K +) reaction in order to study doubly strange hypernuclei, such as AA hypernuclei and E hypernuclei, and in particular how to search for the elusive S = -2 dibaryon H, almost a decade before such searches have been proposed and begun during the late 80s. In these important works, coauthored to various degree by Aerts, Baltz, Gal and Millener, Dover undoubtedly was the driving force. He then quite naturally was drawn into the exciting, perhaps even speculative realm of multistrangeness, both in searching for Strangelets (AGS experiment E864; see Dover's last publication here, T.A. Armstrong et al.) and in recent years exploring together with Gal, Schaffner, Carsten Greiner and Stoecker the existence and subsequently, with a group of Brookhaven collaborators headed by Kahana, the formation of strange hadronic matter.
Dover was one of the first nuclear physicists to point out in the mid 70s the potentiality of using K ÷ meson beams to probe the interior of nuclei. Subsequently he has closely followed the few K + nuclear experiments carried out at the AGS and in 1988, trying to resolve some puzzling consequences of these experiments, he coauthored together with 0375-9474/97
