Search for particles decaying into Zγ at D 0
نویسنده
چکیده
Results on the search for particles decaying into Zγ(→ llγ) are presented. Using roughly 1 fb of data, dileptonplus-photon invariant mass distributions have been examined for an excess over the theoretical predictions. Having observed a good agreement between data and the standard model prediction we set 95% C.L. upper limits on the cross section times branching fraction (σ ×B) of the resonance Zγ production.

متن کاملRatios of W ± γ and Zγ Cross Sections : New Tools in Probing the Weak Boson Sector at the Tevatron
The ratios Rγ,l = B(Z → l+l−) ·σ(Zγ)/B(W → lν) ·σ(W±γ), Rγ,ν = B(Z → ν̄ν) · σ(Zγ)/B(W → lν) · σ(Wγ), RWγ = σ(Wγ)/σ(W), and RZγ = σ(Zγ)/ σ(Z) are studied as tools to probe the electroweak boson self-interactions. As a function of the minimum photon transverse momentum, Rγ,l and Rγ,ν are found to directly reflect the radiation zero present in Wγ production in the Standard Model. All four ratios ar...
متن کاملDiscovering hidden sectors with mono - photon Z ′ searches
In many theories of physics beyond the Standard Model, from extra dimensions to Hidden Valleys and models of dark matter, Z ′ bosons mediate between Standard Model particles and hidden sector states. We study the feasibility of observing such hidden states through an invisibly decaying Z ′ at the LHC. We focus on the process pp → γZ ′ → γXX†, where X is any neutral, (quasi-) stable particle, wh...
