Title: Vertical temperature boundary of the pseudogap under the superconducting dome in the phase diagram of Bi 2 Sr 2 CaCu 2 O 8 + δ

We combine electronic Raman scattering experiments with cellular dynamical mean field theory and present evidence of the pseudogap in the superconducting state of various hole-doped cuprates. In Bi 2 Sr 2 CaCu 2 O 8 + δ we also track the superconducting pseudogap hallmark, a peak-dip feature, as a function of temperature T and doping p , well beyond the optimal one. We show that, at all temperatures under the superconducting dome, the pseudogap disappears at the doping p c , between 0.222 and 0.226, where also the normal-state pseudogap collapses at a Lifshitz transition. This demonstrates that the superconducting pseudogap boundary forms a vertical line in the T - p phase diagram.
