轻MSSM希格斯玻色子玻色子质量达到三环精度

Light MSSM Higgs boson mass to three-loop accuracy

P. Kant, R. V. Harlander, L. Mihaila, M. Steinhauser

摘要:

在最小超对称标准模型(MSSM)中,计算了轻CP偶希格斯玻色子玻色子质量Mh,达到三圈精度。结果用DRbar参数表示,并在计算机程序H3m中实现。计算是基于适当的近似和它们的组合在参数空间的各个区域。三回路对Mh的影响通常为几百MeV的量级,并且与两回路修正的符号相反。剩余的理论不确定性,由于高阶微扰修正估计为小于1 GeV。

英文摘要:

The light CP even Higgs boson mass, Mh, is calculated to three-loop accuracy within the Minimal Supersymmetric Standard Model (MSSM). The result is expressed in terms of DRbar parameters and implemented in the computer program H3m. The calculation is based on the proper approximations and their combination in various regions of the parameter space. The three-loop effects to Mh are typically of the order of a few hundred MeV and opposite in sign to the two-loop corrections. The remaining theory uncertainty due to higher order perturbative corrections is estimated to be less than 1 GeV.
