Changes in properties of heavy hadrons with a charm or a bottom quark are studied in nuclear matter. Effective masses (scalar potentials) for the hadrons are calculated using quark-meson coupling model. Our results also suggest that the heavy baryons containing a charm or a bottom quark will form charmed or bottom hypernuclei, which was first predicted in mid 70's. In addition a possibility of B − -nuclear bound (atomic) states is briefly discussed.PACS number(s): 24. 85, 14.20.L, 14.20.M, 21.65, 11.30.R Keywords: Charmed and bottom hadrons in nuclear medium, Charmed and bottom hypernuclei, Quark-meson coupling model *

Extended calculations of the deuteron's static properties, based on the numerical solution of the Bethe-Salpeter equation, are presented. A formalism is developed, which provides a comparative analysis of the covariant amplitudes in various representations and nonrelativistic wave functions. The magnetic and quadrupole moments of the deuteron are calculated in the Bethe-Salpeter formalism and the role of relativistic corrections is discussed. ͓S0556-2813͑96͒02309-6͔
