    "abstract": "A dynamical model for correlated two-pion and two-kaon exchange in the\nbaryon- baryon interaction is presented, both in the scalar-isoscalar\n($\\sigma$) and the vector-isovector ($\\rho$) channel. The correlations between\nthe two pseudoscalar mesons are taken into account by means of $\\pi\\pi - K\\bar\nK$ amplitudes derived from a meson-exchange model, which is in line with the\nempirical $\\pi\\pi$ data. It is found that correlated $K\\bar K$ exchange plays\nan important role in the $\\sigma$-channel for baryon-baryon states with non-\nvanishing strangeness. The strength of correlated $\\pi\\pi$ plus $K\\bar K$\nexchange in the $\\sigma$-channel decreases with the strangeness of the baryon-\nbaryon system becoming more negative. The results for correlated $\\pi\\pi$-\nexchange in the vector-isovector channel deviate from what is expected in the\nnaive SU(3) picture for genuine $\\rho$-exchange. Shortcomings of a simplified\ndescription in terms of sharp mass $\\sigma$- and $\\rho$-exchange are pointed\nout.",
