Abstract: Experimental systematics in precision measurements at the LHC have reached an unprecedented accuracy, often at the permille level. Theoretical systematics, on the contrary, can be even an order of magnitude larger for selected observables despite of the tremendous progress in perturbative calculations. I will provide a state-of-the-art review of the topic, mainly focused on electroweak precision measurements. I will discuss perturbative and non-perturbative uncertainties (PDFs, scales, intrinsic-kT) affecting the measurements, together with possible strategies to mitigate their impact.
Biography: Giuseppe Bozzi is currently Associate Professor at the University of Cagliari (Italy).
He studied in Pisa for the Master degree and in Florence for the PhD, then he held post-doctoral research positions at the LPSC (Grenoble, FR), KIT (Karlsruhe, DE), University of Milano (IT) and fixed-term research position at the University of Pavia (IT).
His main research interests are in perturbative QCD (fixed-order and all-order predictions for electroweak observables and phenomenology of SM processes at hadron colliders) and non-perturbative QCD (impact of proton internal structure on precision electroweak observables at hadron colliders; fit of transverse momentum dependent (TMD) PDFs from Drell-Yan and Semi-Inclusive DIS data; TMD factorisation).
He has taught several courses at the undergraduate and graduate level, including Analytical Mechanics, Mathematical Methods for Physicists, QCD at Colliders.
