Negative-weights suppression in Monte Carlo samples
This Workshop provides a forum to review, discuss and improve techniques to reduce the impact of negative weights in LHC event generators working at the NLO and beyond. Negative weights induce a significant dilution of the statistical power of large MC event samples, leading to a huge burden for the computing resources required to match the HL-LHC needs. Negative weights pose challenges also to efficient numerical calculations of higher-order parton-level calculations at NNLO and beyond, an issue that will also be covered during the Workshop.
The workshop programme will consist of selected talks in the afternoons, and ample time for discussions and coordination between participants to advance the development and application of methods for negative weight suppression.
The workshop is embedded within the Next-Generation-Triggers (NGT) project, specifically task 1.5, whose aim includes the development of algorithms to improve and accelerate the performance of event generators and higher-order calculations for LHC physics.
A set of rooms has been reserved at the CERN Hostel for the Workshop participants. Check the "Accommodation" item in the left-side menu for details.
