Gauge/string duality and hadronic physics
We review some recent results on phenomenological approaches to strong
interactions inspired in gauge/string duality. In particular, we discuss how
such models lead to very good estimates for hadronic masses.Comment: 5pages, talk presented in I Latin American Workshop on High Energy

Wilson Loops for a quark anti-quark pair in D3-brane space
We calculate static Wilson loops for a heavy quark anti-quark pair in
different positions in the space generated by a large number of coincident
D3-branes. Simple results are obtained from limiting cases of the geodesic
shape. In particular, quark anti-quark static potentials for flat and AdS
spaces are reproduced.Comment: Revised version published in JHE
