      abstract     = {The strangeness S=−2S=−2 baryon–baryon interaction is
                      studied in chiral effective field theory up to
                      next-to-leading order. The potential at this order consists
                      of contributions from one- and two-pseudoscalar-meson
                      exchange diagrams and from four-baryon contact terms without
                      and with two derivatives. SU(3) flavor symmetry is imposed
                      for constructing the interaction in the S=−2S=−2 sector.
                      Specifically, the couplings of the pseudoscalar mesons to
                      the baryons are fixed by SU(3) symmetry and, in general,
                      also the contact terms are related via SU(3) symmetry to
                      those determined in a previous study of the S=−1S=−1
                      hyperon–nucleon interaction. The explicit SU(3) symmetry
                      breaking due to the physical masses of the pseudoscalar
                      mesons (π, K, η) is taken into account. It is argued that
                      the ΞN interaction has to be relatively weak to be in
                      accordance with available experimental constraints. In
                      particular, the published values and upper bounds for the
                      Ξ−pΞ−p elastic and inelastic cross sections apparently
                      rule out a somewhat stronger attractive ΞN force and,
                      specifically, disfavor any near-threshold deuteron-like
                      bound states in that system.},
