Measurement of the Bs mixing parameters from the flavor-tagged decay Bs->JpsiPhi

Likelihood Scans


NO CONSTRAINT on delta_i at all, this is needed for for a meaningful averaging with CDF's fit done in the same way.

Three-dimensional likelihood scan of the Delta(G) vs. phi_s space for fixed values of ct (i.e., slices in lifetime). Name of the file has lifetime in um (fixed). Each file has 9 columns corresponding to the following:

dummy phi_s loglikehood_min delta_1 delta_2 ct(in cm) deltaG(ps^-1) phi_s deltaM_s


"Round 2" - as agreed on with CDF, start with two-dim likelihood scans of Delta(Gamma_s) vs. phi_s, allowing tau_bar(B_s) to float (as well as the phases, i.e., lift the phase constraints of the paper). Fixed values of Delta(Gamma_s) in ps-1 (i.e., slices in Delta(Gamma_s)). As above, each file has 9 columns corresponding to the following:

dummy phi_s loglikehood_min delta_1 delta_2 ct(in cm) deltaG(ps^-1) phi_s deltaM_s



From above, 2-dim plot of likelihood (ps) and (pdf)
