Search For Contact Interactions Using The Dimuon Mass Spectrum In P-P Collisions At Sqrt(s) = 8 Tev At Cms
… known as preons, the manifestation of compositeness can be a four-fermion contact interaction. The experimental signal for contact interactions is a non-resonant enhancement of the number of events in the high-mass region of the dimuon mass spectrum. This dissertation describes a …

Jet physics at ATLAS
… were then considered in the context of a quark compositeness search where a sensitivity to a compositeness scale of Lambda<10TeV can be achieved with 10 inverse femtobarns of data, if the jet energy scale can be constrained to ~1%. An analysis using dijet angular distributions found a similar …

Electron-positron annihilation into photons at √s = 50 to 64 GeV
… and compared to 𝛰(α³) QED. A search for electron compositeness through an e⁺e⁻ γγ contact interaction is conducted, and limits are presented. A search for the pair production of unstable photinos is also presented with limits. Finally, the result of a search for anomalous γγ production is …

A return to the ground: movement, land, and modes of existence in Nkambeni, South Africa
… ways of being. Such entanglements point to a compositeness, building on Francis Nyamnjoh's articulation of the concept, where existence does not emerge through commensurability but through continuous movements across difference. In response, the study proposes a methodological framework …

A measurement of W boson-photon and Z boson-photon cross sections in the muon channel in 1.8 TeV proton-antiproton collisions
… structure for the W and Z bosons with compositeness scale sensitivity up to $\Lambda\sb{W} \sim$ 1 TeV and $\Lambda\sb{Z} \sim$ 250-500 GeV, respectively. These compositeness scale limits probe the possible internal structure of the W to ${\sim}<$2 $\times$ 10$\sp{-4}$fm and internal …

Measurement of the Neutral Current Cross Section and Search for Contact Interactions with the H1 Experiment at HERA
… m (CL=95%) and lower limits on electron-quark compositeness scales ranging from 1.5 to 4.8 TeV. The results are comparable to those of other analyses performed at HERA, LEP or TeVatron.

Advanced Composites for Design and Rehabilitation of Hydraulic Structures
… in load capacity with more than 92% degree of compositeness. By applying basic confinement effect equations, theoretical strengths were in good correlation with experimental values. Following lab work, the rehabilitation work was conducted on submerged concrete discharge ports of Chickamauga …

Linear Sigma Models in QCD and S3 Symmetry for Neutrinos
… reflects, in a phenomenological way, the idea of compositeness for the Higgs sector. It is relatively predictive. In one scenario, it allows for a "hidden" usual Higgs particle in the 100 GeV region and a possible dark matter candidate.</p> <p>Poles in unitarized [<em>pi pi</em>] scattering …
