Holographic correlation functions for open strings and branes

In this paper, we compute holographically the two-point and three-point functions of giant gravitons with open strings. We consider the maximal giant graviton in S⁵ and the string configurations corresponding to the ground states of Z = 0 and Y = 0 open spin chain, and the spinning string in AdS₅ corresponding to the derivative type impurities in Y = 0 or Z = 0 open spin chain as well. We treat the D-brane and open string contribution separately and find the corresponding D3-brane and string configurations in bulk which connect the composite operators at the AdS₅ boundary. We apply a new prescription to treat the string state contribution and find agreements for the two-point functions. For the three-point functions of two giant gravitons with open strings and one certain half-BPS chiral primary operator, we find that the D-brane contributions to structure constant are always vanishing and the open string contribution for the Y = 0 ground state is in perfect match with the prediction in the free field limit.
