The nature of the pairing symmetry of the first heavy fermion superconductor CeCu<sub>2</sub>Si<sub>2</sub> has recently become the subject of controversy. While CeCu<sub>2</sub>Si<sub>2</sub> was generally believed to be a d-wave superconductor, recent low-temperature specific heat measurements showed evidence for fully gapped superconductivity, contrary to the nodal behavior inferred from earlier results. Here, we report London penetration depth measurements, which also reveal fully gapped beh ...[more]
