| Abstract |
We present a search for excited electrons using all data collected by the H1
experiment at HERA at a center-of-mass energy of 318 GeV with an integrated
luminosity of 435 pb-1. The electroweak decay of excited electrons,
e* -> e>g, e* -> eZ, e* -> nW
are considered and possible final states resulting from the $Z$ or $W$ hadronic
decays are taken into account. No evidence for excited electron production is found.
Mass dependent exclusion limits are determined for the ratio of the coupling
to the compositeness scale, f/L.
These limits extend the excluded
region to higher masses than has been possible in previous searches. |
