    "abstract": "Directed flow of neutral strange particles in heavy ion collisions at AGS is\nstudied in the ART transport model. Using a lambda mean-field potential which\nis 2/3 of that for a nucleon as predicted by the constituent quark model,\nlambdas are found to flow with protons but with a smaller flow parameter as\nobserved in experiments. For kaons, their repulsive potential, which is\ncalculated from the impulse approximation using the measured kaon-nucleon\nscattering length, leads to a smaller anti-flow than that shown in the\npreliminary E895 data. Implications of this discrepancy are discussed.",
