Abstract
We report experimental observation of Bardasis-Schrieffer-type s-symmetry c ollective mode in the d-wave high T-c superconductors. The mode persists ab ove T-c in the pseudogap phase of the underdoped superconductors - direct s pectroscopic evidence of the correlations in the particle-particle channel above T-c.
