Description

Differential cross section measurements of the Higgs boson at the LHC are important tools to study possible signs of new physics beyond the Standard Model. A common way to compare the results of the measurements with theory predictions is to unfold the measured spectra to particle level.
An alternative approach, developed in the context of the CMS measurement of the $\mathrm{H} \rightarrow \gamma \gamma$ differential cross sections, is presented. In this approach, MVA methods are used to model the response of the detector differentially as a function of several input variables.
