Baryons and domain walls in an N=1 superconformal gauge theory
- Joseph Henry Laboratories, Princeton University, Princeton, New Jersey 08542 (United States)
Coincident D3-branes placed at a conical singularity are related to string theory on AdS{sub 5}{times}X{sub 5}, for a suitable five-dimensional Einstein manifold X{sub 5}. For the example of the conifold, which leads to X{sub 5}=T{sup 1,1}=[SU(2){times}SU(2)]/U(1), the infrared limit of the theory on {ital N} D3-branes was constructed recently. This is an N=1 supersymmetric SU(N){times}SU(N) gauge theory coupled to four bifundamental chiral superfields and supplemented by a quartic superpotential which becomes marginal in the infrared. In this paper we consider D3-branes wrapped over the 3-cycles of T{sup 1,1} and identify them with baryon-like chiral operators built out of products of {ital N} chiral superfields. The supergravity calculation of the dimensions of such operators agrees with field theory. We also study the D5-brane wrapped over a 2-cycle of T{sup 1,1}, which acts as a domain wall in AdS{sub 5}. We argue that upon crossing it the gauge group changes to SU(N){times}SU(N+1). This suggests a construction of supergravity duals of N=1 supersymmetric SU(N{sub 1}){times}SU(N{sub 2}) gauge theories. {copyright} {ital 1998} {ital The American Physical Society}
