Search for non-resonant pair production of Higgs bosons in the $\rm{b} \bar{\rm{b}} \rm{b} \bar{\rm{b}}$ final state with 13 TeV CMS data

A search for non-resonant Higgs boson pair production in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ is presented. The Higgs bosons are searched in the $\rm{b} \bar{\rm{b}}$ final state. The data have been collected by the CMS experiment at the LHC during the year 2015, and correspond to an integrated luminosity of $2.32~\rm{fb}^{-1}$. No signal is observed and an upper limit of $3880~\rm{fb}$ is set on the cross section of non-resonant Higgs pair-production times branching fraction squared of the $\rm{H} \to \rm{b} \bar{\rm{b}}$ decay.
