Description
A search for nonresonant Higgs boson pair production in the $b\bar{b}\gamma\gamma$ channel is performed using $61.9 \mathrm{fb^{-1}}$ of CMS data at $\sqrt{s} = 13.6\,\mathrm{TeV}$. Two analysis strategies are employed. The 2D fit approach yields a 95% CL upper limit of 11.0 (7.3 expected) times the SM prediction, while the 1D approach gives 7.4 (8.7 expected). Constraints on the self-coupling modifier $\kappa_\lambda$ are set, excluding $\kappa_\lambda$ outside −5 to 12 (2D) and −3.9 to 10.4 (1D).
