Title: Higgs pair production searches with the ATLAS experiment at the Large Hadron Collider
Abstract: Exploring the Higgs potential and electroweak symmetry breaking is one of the main goals of the LHC. Higgs pair production (HH) provides experimental access to the shape of Higgs potential and is the only direct probe of the Higgs self-coupling in proton-proton collisions. In this talk, I will discuss the search for HH production in the 𝑏𝑏𝛾𝛾 channel with the ATLAS experiment at the LHC. I will also present the latest joint results in which the 𝑏𝑏𝛾𝛾, 𝑏𝑏𝜏𝜏 and 𝑏𝑏𝑏𝑏 channels were combined to produce the most stringent limits on Standard Model HH production and the Higgs self-coupling to date. Based on these recent results, I will also discuss our projected sensitivity to HH production at the HL-LHC.
