Measurement of the bb-bar asymmetry using neural networks
Description
The bb-bar asymmetry has been measured using the neural networks. Unlike a conventional method where the c-quark contribution and other backgrounds are subtracted, the b-quark events are identified with the neural networks. The asymmetry is -0.51±0.06(sta)±0.12(sys) and is consistent with the prediction of the standard model with the bb-bar mixing. (author)
