It has recently been observed that MgB2 is a superconductor with a high transition temperature. Here we propose a model of anisotropic s-wave superconductivity which consistently describes the observed properties of this compound, including the thermodynamic and optical response in sintered MgB2 wires. We also determine the shape of the quasiparticle density of states, the tunneling conductance, and the anisotropy of the upper critical field and the superfluid density which should be detectable once single-crystal samples become more generally available. © 2001 The American Physical Society URL:
