Abstract: We consider the intersecting D4-brane and anti-D4-brane model of holographicQCD, motivated by the model that has recently been suggested by Van Raamsdonkand Whyte. We analyze such D4-branes by the use of the action with abi-fundamental ``tachyon- field, so that we find the classical solutionsdescribing the intersecting D4-branes and the U-shaped D4-branes. We show thatthe ``tachyon- field in the bulk theory provides a current quark mass and aquark condensate to the dual gauge theory and that the lowest modes of mesonsobtain mass via tachyon condensation. Then evaluating the properties of a pion,one can reproduce Gell-Mann-Oakes-Renner relation.
