    "abstract": "We have constructed the leading order hyperon-nucleon potential in a chiral\nEffective Field Theory approach. The chiral potential consists of\none-pseudoscalar-meson exchanges and non-derivative four-baryon contact terms.\nThe hyperon-nucleon interactions are derived using SU(3) symmetry, the\nnucleon-nucleon interaction is not considered explicitly since it can not be\ndescribed well with a leading order chiral Effective Field Theory. We solve a\nregularized Lippmann-Schwinger equation and show that a good description of the\navailable hyperon-nucleon scattering data is possible with five free\nparameters. The chiral potential can be used as further input for hypernucleus\nand hypernuclear matter calculations. Preliminary hypertriton calculations\nyielded the correct hypertriton binding energy.",
