A combined statistical analysis of searches for heavy vector boson resonances decaying into pairs of W, Z, or Higgs bosons, as well as into quark pairs ($\mathrm{q\bar{q}}$, $\mathrm{b\bar{b}}$, $\mathrm{t\bar{t}}$, $\mathrm{t\bar{b}}$) or lepton pairs ($\ell^+\ell^-$, $\ell\barν$), with $\ell =$ e, $μ$, $τ$, is presented. The results are based on proton-proton collision data at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb$^{-1}$, collected by the CMS experiment from 2016 to 2018.

A search for dark matter particles produced in association with a Higgs boson decaying to a bottom quark-antiquark pair in proton-proton collisions at $\sqrt{s}$ = 13 TeV is presented. The data, collected with the CMS detector at the LHC, correspond to an integrated luminosity of 101 fb$^{-1}$. [...]

A search is conducted for standard model Higgs bosons with large transverse momentum ($p_\mathrm{T}$) decaying to bottom quark pairs and produced in association with a hadronically decaying W or Z boson at the LHC. The result is based on a dataset of proton-proton collisions at a center-of-mass energy of 13 TeV collected with the CMS detector in 2016$-$2018, corresponding to an integrated luminosity of 138 fb$^{-1}$. [...]

The Higgs boson (H) decay width is determined from the ratio of off- and on-shell production of H $\to$ WW $\to$ e$νμν$ using proton-proton collision data corresponding to an integrated luminosity of 138 fb$^{-1}$ collected at $\sqrt{s}$ = 13 TeV by the CMS experiment at the LHC. The off-shell signal strength is measured as $μ_\text{off-shell}$ = 1.2$^{+0.8}_{-0.7}$. [...]

The fundamental nature of Dark Matter is a central theme of the Snowmass 2021 process, extending across all frontiers. In the last decade, advances in detector technology, analysis techniques and theoretical modeling have enabled a new generation of experiments and searches while broadening the types of candidates we can pursue.

Enamel – the hardest material in the human body – protects against wear during mastication and resists chemical degradation. In the condition termed molar incisor hypomineralisation (MIH), impaired enamel quality leads to rapid tooth decay, hypersensitivity, and frequent need for early tooth extraction. [...]

Microstructural characterization of polycrystalline micropillars remains a significant challenge, particularly under time constraints such as those encountered during in situ or other time-sensitive experimental conditions, where appropriate data checks might assist in taking the right decision and have influence on the outcome of the experiment. In this study, we present a fast and efficient method for estimating local structural properties using scanning X-ray nanodiffraction—a technique widely employed in various dynamic and static micro- and nanoscale material investigations [...]

In order to reduce CO2 emissions, the steel industry shifts its production towardthe usage of higher scrap contents. This transformation leads to an elevation oftramp element concentrations, which can alter the steel’s response during heattreatments. [...]

Laser welding was carried out using a co-axial core-ring beam, with independent control of the power to the coreand the ring. The welding process was observed using high-power X-rays and high-speed imaging equipment.Adjusting the relative powers of the core and the ring beams was found to have profound effects on the shape ofboth the capillary created and the weld melt pool. [...]

Magnesium (Mg) alloys typically exhibit anisotropic mechanical behaviors due to their hexagonal close-packed (hcp) crystal structures,often leading to tension-compression asymmetries. Understanding of the asymmetrical and related deformation mechanisms is crucial fortheir structural applications, particularly in the lightweight transportation industries. [...]
