“…The Higgs and heavy scalar constraints are determined using Lilith-2.2.0 [30] and HiggsSignals-2.4.0 [31] for the SM-like Higgs measurements, and HiggsBounds-5.5.0 [32] for the heavy scalar searches. The input for these codes is generated using a specially written main program for MicrOMEGAs-5.0.8 [33] using model files generated with FeynRules-2.3.36 [34].…”

We re-examine current and future constraints on a heavy dilaton coupled to a simple dark sector consisting of a Majorana fermion or a Stückelberg vector field. We include three different treatments of dilaton-Higgs mixing, paying particular attention to a gauge-invariant formulation of the model. Moreover, we also invite readers to re-examine effective field theories of vector dark matter, which we show are missing important terms. Along with the latest Higgs coupling data, heavy scalar search results, and dark matter density/direct detection constraints, we study the LHC bounds on the model and estimate the prospects of dark matter production at the future HL-LHC and 100 TeV FCC colliders. We additionally compute novel perturbative unitarity constraints involving vector dark matter, dilaton and gluon scattering.

The electroweak (EW) sector of the Minimal Supersymmetric Standard Model (MSSM), with the lightest neutralino as Dark Matter (DM) candidate, can account for a variety of experimental data. This includes the DM content of the universe, DM direct detection limits, EW SUSY searches at the LHC and in particular the so far persistent 3 − 4 σ discrepancy between the experimental result for the anomalous magnetic moment of the muon, (g − 2) µ , and its Standard Model (SM) prediction. The recently published "MUON G-2" result is within 0.8 σ in agreement with the older BNL result on (g − 2) µ . The combination of the two results was given as a exp µ = (11659206.1 ± 4.1) × 10 −10 , yielding a new deviation from the SM prediction of ∆a µ = (25.1 ± 5.9) × 10 −10 , corresponding to 4.2 σ. Using this improved bound we update the results presented in Ref. [1] and set new upper limits on the allowed parameters space of the EW sector of the MSSM. We find that with the new (g − 2) µ result the upper limits on the (next-to-) lightest SUSY particle are in the same ballpark as previously, yielding updated upper limits on these masses of ∼ 600 GeV. In this way, a clear target is confirmed for future (HL-)LHC EW searches, as well as for future high-energy e + e − colliders, such as the ILC or CLIC.

“…• Collider constraints: we ask for agreement with the limits obtained from various searches of additional Higgs bosons at the LHC as well as the requirement that one of the CP-even Higgs Boson should match the properties of the observed SM-like Higgs boson.We evaluate the former constraints with the tools HiggsBouns-5.9.0 [46,47] and the latter with the tools HiggsSignal-2.6.0 [48].…”

The ATLAS and CMS experiments have an ambitious search program for charged Higgs bosons. The two main searches for H ± at the LHC have traditionally been performed in the τ ν and tb decay channels, as they provide the opportunity to probe complementary regions of the Minimal SuperSymmetric Model (MSSM) parameter space. Charged Higgs bosons may decay also to light quarks, H ± → cs/cb, which represent an additional probe for the mass range below m t . In this work, we focus on H ± → µν as an alternative channel in the context of two Higgs doublet model type III. We explored the prospect of looking pp → tbH ± , followed by H ± → µν signal at the LHC. Such a scenario appears in 2HDM type-III where couplings of the charged Higgs are enhanced to µν. Almost all the experimental searches rely on the production and decay of the charged Higgs are taken into account. We show that for a such scenario, the above signal is dominant for most of the parameter space, and H ± → µν can be an excellent complementary search. Benchmarks points are proposed for further Monte Carlo analysis.
