Search for excited electrons in p anti-p collisions at s**(1/2) = 1.96-TeV

Description

We present the results of a search for the production of an excited state of the electron, e*, in proton-antiproton collisions at {radical}s = 1.96 TeV. The data were collected with the D0 experiment at the Fermilab Tevatron Collider and correspond to an integrated luminosity of approximately 1 fb{sup -1}. We search for e* in the process p{bar p} {yields} e*e, with the e* subsequently decaying to an electron plus photon. No excess above the standard model background is observed. Interpreting our data in the context of a model that describes e* production by four-fermion contact interactions and e* decay ... continued below

Description

We present the results of a search for the production of an excited state of the electron, e*, in proton-antiproton collisions at {radical}s = 1.96 TeV. The data were collected with the D0 experiment at the Fermilab Tevatron Collider and correspond to an integrated luminosity of approximately 1 fb{sup -1}. We search for e* in the process p{bar p} {yields} e*e, with the e* subsequently decaying to an electron plus photon. No excess above the standard model background is observed. Interpreting our data in the context of a model that describes e* production by four-fermion contact interactions and e* decay via electroweak processes, we set 95% C.L. upper limits on the production cross section ranging from 8:9 fb to 27 fb, depending on the mass of the excited electron. Choosing the scale for contact interactions to be {Lambda} = 1 TeV, excited electron masses below 756 GeV are excluded at the 95% C.L.
