An interesting decay mode of the Bs meson is into a phi pair: this is a vector-vector decay dominated by b->sss penguin transition which is a sensitive probe for possible new physics effects. The only existing sample of this mode was reconstructed by the CDF experiment from 0.2 fb-1 of data, and consisted of only 8 signal events. Here we present new results based on a clean sample of about 300 Bs->phiphi decays reconstructed by the CDFII detector in a dataset with an integrated luminosity of about 3 fb-1.

Abstract
An interesting decay mode of the Bs meson is into a phi pair: this is a vector-vector decay dominated by b->sss penguin transition which is a sensitive probe for possible new physics effects. The only existing sample of this mode was reconstructed by the CDF experiment from 0.2 fb-1 of data, and consisted of only 8 signal events. Here we present new results based on a clean sample of about 300 Bs->phiphi decays reconstructed by the CDFII detector in a dataset with an integrated luminosity of about 3 fb-1.File in questo prodotto:
