title: Anisotropic dependence of superconductivity on uniaxial pressure in CeIrIn5.
abstract: We measure the effect of uniaxial pressure on the superconducting transition temperature T_{c} in CeIrIn5. We find a linear change in T_{c} with both a-axis and c-axis pressure, with slopes of 56 and -66 mK/kbar, respectively. By comparing results from doping studies and different types of pressure measurements, we separate the influences of hybridization and dimensionality on T_{c}. We find the true geometric influence, for constant hybridization, is partial differentialT_{c}/ partial differential(c/a)=44 K.
