Advancements in Higgs Boson Production Predictions

Recent research by Pedro Cal, Matthew A. Lim, Darren J. Scott, Frank J. Tackmann, and Wouter J. Waalewijn presents significant advancements in the understanding of Higgs boson production processes. The paper, titled "Jet veto resummation for STXS H+1-jet bins at aNNLL'+NNLO," focuses on the Simplified Template Cross Sections (STXS) framework utilized by the ATLAS and CMS experiments at the Large Hadron Collider (LHC). This framework is essential for combining measurements across different decay channels and interpreting them to measure Higgs couplings.

The study emphasizes the need for precise theoretical predictions for various Higgs production processes, particularly in the context of jet production. The authors detail how the production processes are categorized into bins based on the number of jets produced, specifically focusing on the 1-jet bin. They introduce a method for resumming jet-veto logarithms, which enhances the precision of theoretical predictions in this area.

The findings indicate that the resummation at NNLL' accuracy, combined with a matching to full NNLO, provides state-of-the-art predictions for the transverse momentum spectrum in exclusive H+1-jet production. This is particularly relevant for experimentalists aiming to measure Higgs properties with high accuracy.

The implications of this research extend to improving the understanding of Higgs boson interactions and couplings, which are fundamental to the Standard Model of particle physics. Enhanced precision in these measurements can lead to better constraints on new physics beyond the Standard Model, making this work a crucial contribution to ongoing research in high-energy physics.
