Closing the light sbottom mass window from a compilation of e+e− → hadron data


The e+e− → hadron cross section data from PEP, PETRA, TRISTAN, SLC and LEP, at centre-of-mass energies between 20 to 209GeV, are analysed to search for the production of a pair of light sbottoms decaying hadronically via R-parityviolating couplings. This analysis allows the 95%C.L. exclusion of such a particle if its mass is below 7.5GeV/c2. The light… (More)
