Description
I will discuss the GENEVA Monte Carlo framework, that allows to obtain predictions for underlying-event sensitive measurements in Drell-Yan production using PYTHIA8's MPI model, in conjunction with fully-differential NNLO calculation, NNLL' resummation for the 0-jet resolution variable (beam thrust), and NLL resummation for the $1$-jet resolution variable. I will present results for several underlying-event sensitive observables and compare to data from ATLAS and CMS as well as to standalone PYTHIA8 predictions, including a comparison with the recent ATLAS measurement of the beam thrust spectrum, which provides a potential avenue to fully disentangle the physical effects from the primary hard interaction, primary soft radiation, multiple parton interactions, and nonperturbative hadronization.
