“…Calculating the EW corrections to all decays of the SM-like CxSM Higgs boson into SM particles (and, if kinematically allowed into a pair of lighter scalars) will further improve the obtained result. But more importantly, tighter experimental constraints will be obtained in the near future in the upcoming LHC run [51] and even more at the high luminosity stage.…”

The search for dark matter (DM) at colliders is founded on the idea of looking for something invisible. There are searches based on production and decay processes where DM may reveal itself as missing energy. If nothing is found, our best tool to constrain the parameter space of many extensions of the Standard Model (SM) with a DM candidate is the Higgs boson. As the measurements of the Higgs couplings become increasingly precise, higher-order corrections will start to play a major role. The tree-level contribution to the invisible decay width provides information about the portal coupling. Higher-order corrections also gives us access to other parameters from the dark sector of the Higgs potential that are not present in the tree-level amplitude. In this work we will focus on the complex singlet extension of the SM in the phase with a DM candidate. We calculate the one-loop electroweak corrections to the decay of the Higgs boson into two DM particles. We find that the corrections are stable and of the order of a few percent. The present measurement of the Higgs invisible branching ratio, BR(H → invisible ) < 0.11, already constrains the parameter space of the model at leading order. We expect that by the end of the LHC the experimental measurement will require the inclusion of the electroweak corrections to the decay in order to match the experimental accuracy. Furthermore, the only competing process, which is direct detection, is shown to have a cross section below the neutrino floor.

“…As parton-distribution function (PDF), we use the MSTW2008LO [85] PDF set assessed via the LHAPDF 6.2.3 interface [86]. The detector response is simulated using Delphes 3.4.2 [87] employing either the ATLAS-LHC or the HL-LHC [88,89] configuration card provided by Delphes. 2 We assume the center-of-mass energy to be √ s = 13 TeV for both the LHC and the HL-LHC.…”

While $$ \mathcal{CP} $$ CP violation in the Higgs interactions with massive vector boson is already tightly constrained, the $$ \mathcal{CP} $$ CP nature of the Higgs interactions with fermions is far less constrained. In this work, we assess the potential of machine-learning-based inference methods to constrain $$ \mathcal{CP} $$ CP violation in the Higgs top-Yukawa coupling. This approach enables the use of the full available kinematic information. Concentrating on top-associated Higgs production with the Higgs decaying to two photons, we derive expected exclusion bounds for the LHC and the high-luminosity phase of the LHC. We also study the dependence of these bounds on the Higgs interaction with massive vector bosons and their robustness against theoretical uncertainties. In addition to deriving expected exclusion bounds, we discuss at which level a non-zero $$ \mathcal{CP} $$ CP -violating top-Yukawa coupling can be distinguished from the SM. Moreover, we analyze which kinematic distributions are most sensitive to a $$ \mathcal{CP} $$ CP -violating top-Yukawa coupling.

“…After Run 3, in 2027, the LHC will start its high luminosity phase that is expected to provide ATLAS and CMS with 3000 to 4000 fb −1 . A comprehensive review of the physics at the HL-LHC is given here [12]. CMS is currently extending and updating these studies in view of the Snowmass workshop and the projections of the sensitivity to the measurement's of the W ± W ± and W Z Vector Boson Scattering processes [13] are the first of these results.…”
