Higgs pair production in the 2HDM: impact of loop corrections to the trilinear Higgs couplings and interference effects on experimental limits

Abstract The results obtained at the LHC for constraining the trilinear Higgs self-coupling of the detected Higgs boson at about 125 GeV, $$\lambda _{hhh}$$ λ hhh , via the Higgs pair production process have significantly improved during the last years. We investigate the impact of potentially large...
