  Table 10: LVL2 and EF output rates for minimum bias events, LVL2 trigger efficiencies and numbers of expected BsDsA1(mu4) events without or with selection cuts. Rates set in italics are estimates based on the interpolated and extrapolated rates given in Table 7. LVL2 output rates marked by α are downscaled by a factor two, the estimated rate reduction for a Ds vertex requirement at LVL2. For EF output rates marked by β, an estimated rate reduction factor of 60 accounting for EF Bs reconstruction is applied. (See section 3.5 for details.) The results in the columns "LVL2 eff." and NLVL2 outputBsDsAs (without and with selection cuts applied) are based on the BsDsAs(mu4) Monte Carlo data sample. Numbers marked by # are corrected for the estimated efficiency loss by a Ds vertex requirement at LVL2. The integrated luminosities and expected event numbers correspond to one year running at the given instantaneous luminosity (107 seconds).

by opened circles and triangles. The combinatorial background is estimated assuming a factorisation of
applied cuts. Statistics are given for an integrated luminosity 10 fb-1.Fig8.gif

Table 10: LVL2 and EF output rates for minimum bias events, LVL2 trigger efficiencies and numbers of expected BsDsA1(mu4) events without or with selection cuts. Rates set in italics are estimates based on the interpolated and extrapolated rates given in Table 7. LVL2 output rates marked by α are downscaled by a factor two, the estimated rate reduction for a Ds vertex requirement at LVL2. For EF output rates marked by β, an estimated rate reduction factor of 60 accounting for EF Bs reconstruction is applied. (See section 3.5 for details.) The results in the columns "LVL2 eff." and NLVL2 outputBsDsAs (without and with selection cuts applied) are based on the BsDsAs(mu4) Monte Carlo data sample. Numbers marked by # are corrected for the estimated efficiency loss by a Ds vertex requirement at LVL2. The integrated luminosities and expected event numbers correspond to one year running at the given instantaneous luminosity (107 seconds).

Figure 6: Wrong tag fraction as functions of tagging muons transverse momentum pT(μ) in (a) and (b) and wrong tag fractions as functions of signal Monte Carlos Bs transverse momentum pT(Bs) in (c) and (d). The wrong tag fraction is shown with mixing of the tagging side b hadron and without mixing. Without mixing, the different sources of wrong tags are shown. The main contribution is coming from b→c→μ followed by additional c pairs. Additional sources shown are muons coming from J/ψ, φ, ρ, η and τ.

Rates set in italics are estimates based on the interpolated and extrapolated rates given in Table 7. LVL2 output rates marked by α are downscaled by a factor two, the estimated rate reduction for a Ds vertex requirement at LVL2. For EF output rates marked by β, an estimated rate reduction factor of 60 accounting for EF Bs reconstruction is applied. (See section 3.5 for details.) The results in the columns "LVL2 eff." and NLVL2 outputBsDsAs (without and with selection cuts applied) are based on the BsDsAs(mu4) Monte Carlo data sample. Numbers marked by # are corrected for the estimated efficiency loss by a Ds vertex requirement at LVL2. The integrated luminosities and expected event numbers correspond to one year running at the given instantaneous luminosity (107 seconds).

Figure 6: Wrong tag fraction as functions of tagging muons transverse momentum pT(μ) in (a) and (b) and wrong tag fractions as functions of signal Monte Carlos Bs transverse momentum pT(Bs) in (c) and (d). The wrong tag fraction is shown with mixing of the tagging side b hadron and without mixing. Without mixing, the different sources of wrong tags are shown. The main contribution is coming from b→c→μ followed by additional c pairs. Additional sources shown are muons coming from J/ψ, φ, ρ, η and τ.

Table 10: LVL2 and EF output rates for minimum bias events, LVL2 trigger efficiencies and numbers of expected BsDsA1(mu4) events without or with selection cuts. Rates set in italics are estimates based on the interpolated and extrapolated rates given in Table 7. LVL2 output rates marked by α are downscaled by a factor two, the estimated rate reduction for a Ds vertex requirement at LVL2.

This page contains approved plots and results in the order as they appear in the CSC note. Only the CSC note contains all the relevant information and should thus be consulted if any of the plots is used.

Since the CSC book is not yet published, you have to add 'preliminary' to all plots.
