Double Higgs production will be a key observable to probe the structure of the Higgs potential. In this talk I will present the first step in obtaining the electroweak corrections to double Higgs production by considering the leading Yukawa corrections to this process in the high energy limit. I will describe the methods we used and show that we obtain precise numerical results down to $p_T...
In this talk we will discuss the production of three Higgs bosons in the LHC and at a proton-proton collider running at a centre-of-mass energy of 100 TeV. We will argue that the seemingly challenging 6-botton jets final state is a very good candidate to investigate triple Higgs production within and beyond the SM in proton-proton colliders. In particular we will consider three different...
The dominant Higgs pair production process in the HL-LHC is gluon fusion, which we study in the framework of the Two Higgs Doublet Model. As a key observable we evaluate the invariant mass distribution of two Higgses at 125 GeV in the final state. We analyze in particular the contribution of the resonant diagram involving a heavy CP-even Higgs boson exchange. We analyze the potential...
The Higgs boson pair production via gluon-gluon fusion and vector boson fusion in the bbμ+μ− final state at the LHC is studied to probe the Higgs self-coupling κλ and the four-boson HHVV coupling κ2V for the first time. A cut-based analysis and a machine learning analysis using boosted decision trees are performed with categorizations and optimizations depending on the variations of these...
