Abstract
We present a search for high-mass neutral resonances using dimuon data corresponding to an integrated luminosity of 2.3 fb$^{-1}$ collected in {$p\bar p$} collisions at {$\sqrt{s}$ = 1.96 TeV} by the CDF II detector at the Fermilab Tevatron. No significant excess above the standard model expectation is observed in the dimuon invariant-mass spectrum. We set 95% confidence level upper limits on $\sigma \cdot BR (p \bar{p} \to X \to \mu \bar{\mu})$, where $X$ is a boson with spin 0, 1, or 2. Using these cross section limits, we determine lower mass limits on sneutrinos in R-parity-violating supersymmetric models, $Z'$ bosons, and Kaluza-Klein gravitons in the Randall-Sundrum model.

Improved constraints on Z′ bosons from electroweak precision data

TL;DR: In this article, the mass of the neutral Z' boson, predicted in all such models, and on the Z?Z' mixing angle, were investigated and the precision electroweak (EW) data strongly constrain?ZZ' to very small values and for most models, they find lower limits on MZ' of (1TeV).

Search for physics beyond the standard model in dilepton mass spectra in proton-proton collisions at √s=8 TeV

Vardan Khachatryan, +2198 more
TL;DR: In this article, the authors used a large extra dimensions model and a quark and lepton compositeness model with a left-left isoscalar contact interaction to search for both narrow resonances and broad deviations from standard model predictions.

Electroweak limits on general new vector bosons

TL;DR: In this article, the authors study extensions of the Standard Model with general new vector bosons and derive the corresponding effective Lagrangian, valid at energies lower than the mass of the extra vectors, and use it to extract limits from electroweak precision observables.

Dark matter and a new gauge boson through kinetic mixing

TL;DR: In this paper, the authors considered a hidden sector model of dark matter which is charged under a hidden U(1) − ε -gauge symmetry and showed that the spin-independent elastic cross section of the dark matter off nucleons is mostly below the current experimental limits, but within the future sensitivity.
