abstract
Despite intensive searches at the LHC, no new fundamental particle has been discovered since the discovery of the 125 GeV Higgs boson. In general, a new physics discovery is challenging without a UV-complete model because different channels and observables cannot be combined directly and unambiguously. Moreover, without indirect hints for new particles, the parameter space to be searched is huge, resulting in diminished significance due to the look-elsewhere effect. Several LHC searches with multiple leptons in the final state point towards the existence of a new Higgs boson with a mass in the 140-160 GeV range, decaying mostly to a pair of W bosons. This dominant decay mode motivates a Higgs triplet with zero hypercharge, which also predicts a heavier-than-expected $W$-boson as indicated by the CDF-II measurement. Within this simple and predictive model, we simulate and combine channels of associated di-photon production. Considering the run-2 results of ATLAS, including those presented recently at the Moriond conference, a significance of 4.3$\sigma$ is obtained for a mass of 152 GeV. This is the largest statistical evidence for a new narrow resonance observed at the LHC.

Multi-step Strong First-Order Electroweak Phase Transitions in the Inverted Type-I 2HDM: Parameter Space, Gravitational Waves, and Collider Phenomenology
In the inverted Type-I 2HDM, one-step and two-step strong first-order electroweak phase transitions live in largely separate parameter regions, and LISA-detectable gravitational wave signals come predominantly from th...

Searching for charged Higgs bosons in top decays via the $t^*b$ channel
Reinterpretation of ATLAS dileptonic ttbb data sets 1.9–2.9% limits on Br(t→H±b)×Br(H±→t*b) for mH±=110–165 GeV, competitive in top-philic and top-specific 2HDMs.

Searching for Di-Higgs Signatures of Light Charged Scalars
A roughly 130 GeV charged Higgs explaining the ATLAS t to bH+ excess and B-meson anomalies can be constrained, and perhaps discovered, by recasting SM di-Higgs 4b searches at the LHC.

A joint explanation for the soft lepton and monojet LHC excesses in the wino-bino model
A combined fit to four LHC Run 2 searches prefers a wino-bino supersymmetric spectrum with m(wino) ~ 320 GeV and mass splitting ~ 20 GeV, compatible with bino dark matter.

Light Scalars in the Extended Georgi-Machacek Model
A global fit of the Georgi-Machacek and extended Georgi-Machacek models finds that the 95 GeV diphoton and bottom-quark excesses are compatible with the 125 GeV Higgs data, while the ditau excess is not, and it sets u...

Multi-Lepton Probes of the Drell-Yan Production of Triplet Higgses
The ΔSM real Higgs triplet model is consistent with LHC triboson excesses but predicts more events than observed and is not preferred over the Standard Model.

Dark clouds to silver linings over the hyperchargeless scalar triplets
Under current constraints, the inert triplet model is insufficient for dark matter and for a first-order phase transition, while the non-inert triplet model retains a narrow 150 to 275 GeV window for a strong two-step...
