Seminario INFN di fenomenologia delle particelle elementari 

In the precision era of the LHC, it is of utmost importance having a good control on the theoretical uncertainties.

With particular attention to the inclusive Higgs cross section in gluon fusion, where scale variation notoriously underestimates the uncertainty from missing higher orders, I will discuss alternative options.

The ambitious goal is to provide a reliable recipe with a meaningful statistical interpretation. 

This will be useful for consistent experimental analyses, and also for fitting reliable parton distributions.
