Measurement of the branching fraction ratio b = j

HIGHLIGHTS

• who: . et al. from the (UNIVERSITY) have published the Article: Measurement of the branching fraction ratio B = J, in the Journal: (JOURNAL)
• what: The analysis updates the previous LHCb measurement of RB , using the full pp pffiffiffi collision data collected by LHCb in 2011 and 2012 at s=7 TeV and 8 TeV, respectively, corresponding to an integrated luminosity of 3 fb-1.
• how: The distributions of all training variables from simulation and backgroundsubtracted data are compared where the background subtraction is performed using the sPlot technique taking the B- c invariant mass . . .
