Title: From Heavy-Ion Collisions to Quark Matter (2/3)

The art of experimental (high-energy heavy-ion) physics 1) many experimental issues are crucial to properly understand the measurements and derive a correct physics interpretation: Acceptance and phasmore »e space windows; Efficiencies (of track reconstruction, vertexing, track matching, trigger, etc); Resolutions (of mass, momenta, energies, etc); Backgrounds, feed-downs and "expected sources"; Data selection; Monte Carlo adjustments, calibrations and smearing; luminosity and trigger conditions; Evaluation of systematic uncertainties, and several others. 2) "New Physics" often appears as excesses or suppressions with respect to "normal baselines", which must be very carefully established, on the basis of "reference" physics processes and collision systems. If we misunderstand these issues we can miss an important discovery...or we can "discover" non-existent "new physics."« less
