AI 中文总结

AI 中文摘要
我们开展了希格斯玻色子与粲夸克、底夸克伴随产生的详细NLO+PS研究，重点关注H+c末态的建模。我们系统比较了有质量和无质量味方案的预言，量化了能标和味方案的不确定性，并评估了干涉及圈诱导贡献的影响。特别强调了通过粲夸克汤川融合产生希格斯的过程，对此我们在13.6 TeV能量下，将NLO+PS预言与四味方案中c\bar{c}H产生的NNLO+PS计算进行了对比。基于这些结果，我们为LHC分析中c\bar{c}H产生的模拟提供了首个实用建议。
英文摘要
We present a detailed NLO+PS study of Higgs-boson production in association with charm and bottom quarks, with particular focus on the modelling of the H+c final state. We systematically compare predictions in massive and massless flavour schemes, quantify scale and flavour-scheme uncertainties, and assess the impact of interference and loop-induced contributions. Special emphasis is placed on the Higgs production via charm Yukawa fusion, for which we compare NLO+PS predictions with a NNLO+PS calculation of $c\bar{c}H$ production in the four-flavour scheme at 13.6 TeV. Based on these results, we provide the first practical recommendations for the simulation of $c\bar{c}H$ production in LHC analyses.
