Query: Vertical temperature-boundary of the pseudogap under the superconducting
  dome of the Bi2Sr2CaCu2O8+d phase-diagram   Combining electronic Raman scattering experiments with cellular dynamical
mean field theory, we present evidence of the pseudogap in the superconducting
state of various hole-doped cuprates. In Bi2Sr2CaCu2O8+d we 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 pc, 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.
