      abstract     = {Near-threshold ΛΛ¯ mass spectra for the reactions
                      e+e−→ηΛΛ¯ and e+e−→ϕΛΛ¯ are investigated
                      with an emphasis on the role played by the interaction in
                      the ΛΛ¯ system. A variety of ΛΛ¯ potential models is
                      employed that have been established in the analysis of data
                      on pp¯→ΛΛ¯ in the past. It is shown that the
                      near-threshold enhancement observed for the two e+e−
                      reactions can be reproduced by considering the ΛΛ¯
                      final-state interaction in the partial waves suggested by
                      the helicity-angle analysis of the experiments. For
                      e+e−→ηΛΛ¯ the same ΛΛ¯ S-wave interaction as in
                      e+e−→ΛΛ¯ is relevant and with it a consistent
                      description of the pertinent measurements can be achieved.
                      It is pointed out that a nonzero threshold cross section as
                      observed for the latter reaction is not supported by the new
                      ηΛΛ¯ data.},
