Query: Multi Higgs production via photon fusion at future multi-TeV muon
  colliders   Multi-TeV muon colliders promise an unprecedented potential for exploring the
particle-physics energy frontier, and, at the same time, can probe with
fantastic accuracy the precise structure of the Standard Model, and in
particular of the Higgs boson sector. Here we consider the possibility to
measure the loop-suppressed single-, double-, triple-Higgs boson production
mediated by the collinear-photon scattering in the channels
$\mu^+\mu^-\to\mu^+\mu^-\gamma^\ast \gamma^\ast \to \mu^+\mu^- [H,HH,HHH]$. We
study total rates and kinematical distributions in the Standard Model, and
compare them with the corresponding vector-boson-fusion processes $V^\ast
V^\ast\to H,HH,HHH$ at muon collisions center-of-mass energies in the range
between 1.5 and 100 TeV. Possible strategies for enhancing the $\gamma\gamma\to
H,HH,HHH$ signal over the dominant vector-boson-fusion production are proposed.
The sensitivity of total rates to possible anomalies in the Higgs-boson
self-couplings is also discussed.
