    "abstract": "A new QCD sum rule analysis on the spin-isospin averaged $\\rho$, $\\omega$ and\n$\\phi$ meson-nucleon scattering lengths is presented. By introducing the\nconstraint relation on the the low energy limit of the vector-current nucleon\nforward scattering amplitude, we get $a_\\rho=-0.47\\pm 0.05$ fm,\n$a_\\omega=-0.41\\pm 0.05$ fm and $a_\\phi=-0.15\\pm 0.02$ fm, which suggests that\nthese V-N interactions are attractive. It is also proved that the previous\nstudies on the mass shift of these vector mesons in the nuclear medium are\nessentially the ones obtained from these scattering lengths in the linear\ndensity approximation.",
