Closing the light sbottom mass window from a compilation of e+e- -> hadron data
Abstract
The e+e- -> hadron cross section data from PEP, PETRA, TRISTAN, SLC and LEP, at centre-of-mass energies between 20 to 209 GeV, are analysed to search for the production of a pair of light sbottoms decaying hadronically via R-parity-violating couplings. This analysis allows the 95%C.L. exclusion of such a particle if its mass is below 7.5 GeV/c2. The light sbottom mass window is closed.

19 pages, 8 figures, 10 tables To be published in Physics Letters. This new version has been reshuffled with respect to the original version to include the suggestions from the Referees of Physics Letters. In particular, the e+e- -> hadron data compilation and combination method are now described in detail, to avoid references to unpublished material. A more realistic treatment of systematic uncertainties also improved the limit slightly
