The LHC's sqrt(s) = 13 TeV proton-proton collisions open a new regime in which the predictions of QCD may be precisely tested via production measurements. LHCb undertook an Early 2015 Measurements campaign to coordinate the operational and analysis activities that are required for rapid completion of such production measurements. The Early Measurements campaign is now bearing fruit with the recent publication of J/psi cross-sections and the imminent publication of charm hadron cross-sections. These are the first results to rely on LHCb's new real-time calibration system, in which the sub-detectors are promptly calibrated and the full event reconstruction of the software High Level Trigger has analysis-quality precision. This seminar will discuss the LHCb real-time calibration system and our recent charm and J/psi production measurements at sqrt(s) = 13 TeV.
