Higgs赝观测量与辐射修正

Higgs Pseudo Observables and Radiative Corrections

Marzia Bordone, Admir Greljo, Gino Isidori, David Marzocca, Andrea Pattori

摘要:

我们展示了如何领先的辐射校正可以实现一般的描述$h\to 4\ell$衰变的伪观测量(PO)的装置。包括这样的修正,PO描述的$h\to 4\ell$衰变可以匹配到下一个领先的顺序电弱计算内和超出标准模型(SM)。特别是,我们证明,包括这样的修正的完整的下一个领先的顺序标准模型预测的$h\to 2e2μ$双轻子质谱恢复在1%的准确度。还简要讨论了辐射修正对非标准PO的影响。

英文摘要:

We show how leading radiative corrections can be implemented in the general description of $h\to 4\ell$ decays by means of Pseudo Observables (PO). With the inclusion of such corrections, the PO description of $h\to 4\ell$ decays can be matched to next-to-leading-order electroweak calculations both within and beyond the Standard Model (SM). In particular, we demonstrate that with the inclusion of such corrections the complete next-to-leading-order Standard Model prediction for the $h\to 2e2μ$ dilepton mass spectrum is recovered within 1% accuracy. The impact of radiative corrections for non-standard PO is also briefly discussed.
