Search for high-mass e+e- resonances in pp collisions at sqrt[s]=1.96 TeV.

Abstract:

A search for high-mass resonances in the e+e- final state is presented based on 2.5 fb(-1) of sqrt[s]=1.96 TeV pp collision data from the CDF II detector at the Fermilab Tevatron. The largest excess over the standard model prediction is at an e+e- invariant mass of 240 GeV/c2. The probability of observing such an excess arising from fluctuations in the standard model anywhere in the mass range of 150-1000 GeV/c2 is 0.6% (equivalent to 2.5sigma). We exclude the standard model coupling Z' and t...
