Abstract:	摘要： A measurement of the$ \Lambda_{\mathrm{b}}^0 $lifetime using the decay$ {{{\Lambda_{\mathrm{b}}^0\to J}} \left/ {{\psi \varLambda }} \right.} $in protonproton collisions at$ \sqrt{s}=7 $TeV is presented. The data set, corresponding to an integrated luminosity of about 5 fb −1 , was recorded with the CMS experiment at the Large Hadron Collider using triggers that selected dimuon events in the J/ ψ mass region. The$ \Lambda_{\mathrm{b}}^0 $lifetime is measured to be 1.503 ± 0.052 (stat.) ± 0.031 (syst.) ps. 出版者： United States: Springer 出版日期： 2013-07 出處： The journal of high energy physics, 2013-07, Vol.2013 (7), Article 163 資源來源： ProQuest Open Access Content Collection 版權： CC0 1.0 - Universal 識別號： ISSN: 1029-8479 識別號： ISSN: 1126-6708 識別號： ISSN: 1127-2236 識別號： EISSN: 1029-8479 識別號： DOI: 10.1007/JHEP07(2013)163
