    “…After a brief introduction of the important observables in this game, I recall the accuracy (10-3) with which the Standard Model (SM) works for the light fermions (section 2) In comparison, the 2% (resp. 7%) discrepancy in R b (resp. R c) seems enormous (section 3). Of course, given the difficulty of the measurement, one should first ask how it could be wrong, (section 4), before trying to find how new physics could explain it (section 5). …”

    “…The measurements of R/sub b/ and R/sub c/, the fraction of hadronic Z boson decays into bb and cc final states, provide a tight test on the Standard Model. …”

    “…These jets cluster particle shower products into calculable objects, which are then used to obtain information about parent particles. Large-R (R = 1.0) jets combine these products into one jet that spans 2 radians, while small-R (R = 0.4) jets are used to further refine individual b-quark trajectories. …”
