      abstract     = {The origin of unconventional superconductivity, including
                      high-temperature and heavy-fermion superconductivity, is
                      still a matter of controversy. Spin excitations instead of
                      phonons are thought to be responsible for the formation of
                      Cooper pairs. Using inelastic neutron scattering, we present
                      the first in-depth study of the magnetic excitation spectrum
                      in momentum and energy space in the superconducting and the
                      normal states of CeCu2Si2. A clear spin excitation gap is
                      observed in the superconducting state. We determine a
                      lowering of the magnetic exchange energy in the
                      superconducting state, in an amount considerably larger than
                      the superconducting condensation energy. Our findings
                      identify the antiferromagnetic excitations as the main
                      driving force for superconducting pairing in this
                      prototypical heavy-fermion compound located near an
                      antiferromagnetic quantum critical point.},
