| Resumo(s): | A measurement of the 0 b lifetime and mass in the decay channel 0 b ! J=c ð þ Þ 0ðp Þ is presented. The analysis uses a signal sample of about 2200 0 b and 0 b decays that are reconstructed in 4:9 fb 1 of ATLAS pp collision data collected in 2011 at the LHC center-of-mass energy of 7 TeV. A simultaneous mass and decaytime maximum likelihood fit is usedto extract the 0 b lifetime and mass. They are measured to be b ¼1:4490:036ðstatÞ0:017ðsystÞ ps and m b ¼5619:70:7ðstatÞ1:1ðsystÞ MeV. |
