      abstract     = {The Higgs self-coupling 𝜆 governs the shape of the Higgs
                      potential and its precise determination is one of the main
                      goals at future colliders. Here we present a new study based
                      on fast simulations at the FCC-hh, assuming √𝑠 = 100
                      TeV and an integrated luminosity of 30 ab$^{−1}$. The
                      $𝜅_𝜆$ selfcouplingmodifier is determined from double
                      Higgs production in two channels, the 𝑏𝑏𝛾𝛾 and
                      the 𝑏𝑏ℓℓ + 𝐸T𝑚𝑖𝑠𝑠 final states. The
                      𝑏𝑏𝛾𝛾 drives the precision, down to 3.6\%, while
                      the 𝑏𝑏ℓℓ + 𝐸T𝑚𝑖𝑠𝑠achieves an
                      uncertainty of 22\%, however being a benchmark measurement
                      for the impact of pileup. A further study on the resolution
                      of the invariant mass $𝑚_{𝑏𝑏}$ of the two b-jets in
                      𝑏𝑏𝛾𝛾 shows that, with an optimal calorimeter and
                      b-tagging algorithm achieving a resolution of 3\% on
                      $𝑚_{𝑏𝑏}$, a precision ≤ 2\% on $𝜅_𝜆$ can be
                      reached.},
