“…The stop masses can be as light as about 1 TeV, which has already been probed at the current LHC experiments depending on the decay channels of stop and chargino [42], and these bounds are applicable over the fundamental parameter space of MSSM. LHC-Run3 is expected to probe the stop mass up to about 1.4 TeV [43], and the High Luminosity LHC (HL-LHC) can extend this to about 2 TeV. The diagonal line in this plane shows the regions where m t1 = m g and as shown, all muon g − 2 solutions compatible with the relic density conditions (red and blue) remain under the diagonal line, which indicates m g m t1 .…”

Inspired by the latest measurement of muon g-2 by the Fermilab Experiment, we revisit a class of supersymmetric models in which non-universality at M GUT allows us to realize relatively light sleptons in the few hundred GeV range. These sleptons provide additional contributions to muon g-2 that can be arranged to reconcile theory and experiment. The solutions compatible with the muon g − 2 resolution typically predict light sleptons, charginos and neutralinos. We show how these solutions can be probed during LHC-Run3. A direct impact on the chargino mass is observed such that the chargino can be probed up to about 800 GeV during the Run3 experiments. Despite such a direct impact, it is still possible to realize lighter chargino masses which can escape detection due to the chirality mixture of the lighter slepton states. The colored squarks as well as the gluino turn out to be heavier than about 3-4 TeV if the LSP neutralino satisfies the Planck bound on the dark matter relic abundance. We highlight a variety of benchmark points and, in particular, coannihilation scenarios with dark matter candidates that will be tested in the ongoing and planned direct and indirect detection experiments. By relaxing the requirement that the LSP neutralino saturates the relic dark matter abundance, we are able to find solutions with gluino and squark masses in a range that may be accessible at LHC-Run3.

“…The associated production of A i with the photon is calculated by M adGraph5 [140]. Note that this approximation yields about 1% or less uncertainty in our calculations compared to the full matrix element consideration [141]. In these events, the missing transverse energy is approximately determined by the mass of the CP-odd Higgs boson involved in the process.…”

We explore the Higgs boson implications of a class of supersymmetric models, which extends the MSSM gauge group by a U (1) symmetry, which is broken at low energy scales by VEVs of four MSSM singlet fields. These singlets also form a secluded sector, and one of them is allowed to interact with the MSSM Higgs fields directly. After the U (1) and electroweak symmetry breaking, the low scale spectra include six CP-even and 4 CP-odd Higgs bosons, whose masses can lie from 80 GeV to 2-3 TeV. We find that the heavy CP-even Higgs bosons can be probed through their decays into a pair of SM gauge bosons currently up to about m h i 1.5 TeV, while their probe can be extended to about m h i 2.5 TeV in near future. The most interesting feature of the low scale spectra in the class of Secluded U (1) models is to include two light CP-odd Higgs bosons whose masses are bounded at about 250 GeV by the current collider and DM experiments, when the LSP neutralino is mostly formed by the MSSM singlets. These light CP-odd Higgs bosons should be formed by the MSSM singlet scalars to be consistent with the current constraints. Despite their singlet nature, they can be traced through their associated production with photons. In our work, we consider their productions at the collider experiments together with photons, and we realize that these light Higgs bosons can potentially be probed during Run-3 experiments of LHC when they are lighter than about 100 GeV. We also show that Run-4 and HL-LHC experiments will be able to probe these light scalars up to about 250 GeV.
