Abstract

A proposed high energy Future Circular Hadron-Electron Collider would provide sufficient energy in a clean environment to probe di-Higgs production. Using this channel we show that the azimuthal angle correlation between the missing transverse energy and the forward jet is a very good probe for the non-standard hhhhhh and hhWWhhWW couplings. We give the exclusion limits on these couplings as a function of integrated luminosity at a 9595\% C.L. using the fiducial cross sections. With appropriate error fitting methodology we find that the Higgs boson self coupling could be measured to be ghhh(1)=1.000.17(0.12)+0.24(0.14)g^{(1)}_{hhh} = 1.00^{+0.24(0.14)}_{-0.17(0.12)} of its expected Standard Model value at s=3.5(5.0)\sqrt s = 3.5(5.0) TeV for an ultimate 10 ab1^{-1} of integrated luminosity.
