Description
The GENEVA Monte Carlo event generator interfaces fully-differential fixed order calculations up to NNLO with high-order resummation in a 0-jet resolution variable and with parton showers, by combining them at the appropriate scales. The resulting simulated events have therefore NNLO accuracy in the fixed-order region and NNLL' accuracy in the resummation region. The parton shower matching is performed such that the nominal accuracy is not spoiled, and incorporates the hadronization and MPI effects.
In the last few years, many colour singlet production processes have been implemented in GENEVA at a theoretical accuracy of NNLO+NNLL' in the 0-jettiness or transverse momentum resolution variables. Some steps have been undertaken towards the implementation of processes with coloured final state. Parallel to these developments, a number of general technical improvements have been integrated into this framework. In this talk we introduce the GENEVA method, make an overview of the currently available processes, and demonstrate the main improvements that have been implemented so far.
