Precision measurement of the B[0 over s]–[– over B][0 over s] oscillation frequency with the decay B[0 over s]→D[– over s]π[superscript +]
A key ingredient to searches for physics beyond the Standard Model in B[0 over s] mixing phenomena is the measurement of the B[0 over s]–[– over B][0 over s] oscillation frequency, which is equivalent to the mass difference Δm[subscript s] of the B[0 over s] mass eigenstates. Using the world's...

| description | A key ingredient to searches for physics beyond the Standard Model in B[0 over s] mixing phenomena is the measurement of the B[0 over s]–[– over B][0 over s] oscillation frequency, which is equivalent to the mass difference Δm[subscript s] of the B[0 over s] mass eigenstates. Using the world's largest B[0 over s] meson sample accumulated in a dataset, corresponding to an integrated luminosity of 1.0 fb[superscript −1], collected by the LHCb experiment at the CERN LHC in 2011, a measurement of Δm[subscript s] is presented. A total of about 34 000 B[0 over s] → D[− over s]π[superscript +] signal decays are reconstructed, with an average decay time resolution of 44 fs. The oscillation frequency is measured to be Δm[subscript s] = 17.768 ± 0.023 (stat) ± 0.006 (syst) ps[superscript −1], which is the most precise measurement to date. |
