| contents | In type IIB supergravity (SUGRA), in the extremal background of a number N_c of D3-branes we consider a number N_f of probe D7-branes extended along all four D3-brane directions, (x_0,x_1,x_2,x_3). Using (x_2,x_3) to define complex coordinates (z,\bar{z}) and defining the D7-branes' worldvolume scalars as (y,\bar{y}), we prove that any holomorphic function y(z) or antiholomorphic function y(\bar{z}) is a BPS solution of the D7-branes' equations of motion preserving N=(4,0) or (0,4) supersymmetry (SUSY) along (x_0,x_1), respectively. In the near-horizon geometry, five-dimensional Anti-de Sitter (AdS) spacetime times a five-sphere, the AdS/Conformal Field Theory correspondence states that type IIB SUGRA is holographically dual to four-dimensional N=4 supersymmetric SU(N_c) Yang-Mills theory at large N_c and large 't Hooft coupling, and the N_f D7-branes are dual to N_f N=2 hypermultiplets in the fundamental representation, i.e. flavour fields. Our D7-brane solutions are dual to a position-dependent hypermultiplet mass m that is holomorphic, m(z), or antiholomorphic, m(\bar{z}). We provide field theory proofs, valid for any N_c, N_f, and 't Hooft coupling, that such m preserve N=(4,0) or (0,4) SUSY along (x_0,x_1). We also perform holographic calculations with probe D7-branes to show that the theory with such m has zero energy and zero expectation value of the mass operator, and that a zero of m is dual to a superconformal defect described by chiral fermions along (x_0,x_1). |
