Investigating the Supersymmetric Explanation of Anomalous CDF lepton ( s ) photon ( s ) Missing - E T Events
The recent excess over the Standard Model prediction in the μγ missingET (6 ET ) channel reported by CDF can be well-explained by resonant smuon production with a single dominant R-parity violating coupling λ211, in the context of models where the gravitino is the lightest supersymmetric particle. The slepton decays to the lightest neutralino and a muon followed by neutralino decaying to a grav...
متن کاملCombined fits to the supersymmetric explanation of anomalous lepton - γ - missing E T events
The CDF experiment reported a lepton photon missing transverse energy (6 ET ) signal 3σ in excess of the Standard Model prediction in Tevatron Run I data. The excess can be explained by the resonant production of a smuon, which subsequently decays to a muon, a photon and a gravitino. Here, we perform combined fits of this model to the CDF γl 6 ET excess, the D0 measurement of the same channel a...
متن کاملAmbulance Chasing Anomalous CDF μγ Missing-ET Events With Supersymmetry
CDF recently reported an excess of events in the μγ missing ET ( ET ) channel that disagrees with the Standard Model prediction. No such excess was observed in the eγ ET channel. We explain the excess via resonant smuon production with a single dominant R-parity violating coupling λ211, in the context of models where the gravitino is the lightest supersymmetric particle. The slepton decays to t...
متن کاملLeptons and Photons
It is assumed that three lepton families (ν e , e), (ν µ , µ), (ν τ , τ) carry charges, which are sources of electronic, muonic and tauonic massless vector particles, respectively. Various manifestations of these hypothetical photons are discussed. We know only one photon that is coupled to the electric charge of particles. One of the most fundamental properties of the electric charge is its co...
متن کاملExclusive High Mass Di-leptons in CDF
In the Collider Detector at Fermilab, CDF, we have measured central exclusive production, p + p̄ → p + X + p̄, where X is a pair of leptons or photons and nothing else. In this talk I focus on central masses M(X) > 8 GeV/c. We measured QED production γγ → ee, μμ up to M(X) = 75 GeV/c, and candidates for photoproduction of Upsilons, γIP → Y (1S), Y (2S), Y (3S). I report a search for exclusive pho...
