从低能到高能的电弱精密物理

Electroweak Precision Physics from Low to High Energies

S. Heinemeyer

摘要:

电弱精密观测量(EWPO)可以提供关于标准模型(SM)最后一个未知参数--希格斯玻色子质量M_H^SM的有价值的信息。EWPO还可以限制新物理模型(NPM)的参数空间,例如最小超对称标准模型(MSSM)。我们分别从W玻色子质量、有效轻子混合角、μ子反常磁矩和电偶极矩等几个方面对它们的限制进行了评述。在MSSM中,最轻的Higgs玻色子质量M_h也被讨论为一个精确的可观测值。利用EWPO,辅以B物理观测值和天体物理数据,可以间接确定超对称性和M_h的首选质量标度。

英文摘要:

Electroweak precision observables (EWPO) can give valuable information about the last unknown paramter of the Standard Model (SM), the Higgs-boson mass M_H^SM. EWPO can also restrict the parameter space of new physics models (NPM) such as the Minimal Supersymmetric Standard Model (MSSM). We review the respective constraints from the W boson mass, the effective leptonic mixing angle, the anomalous magnetic moment of the muon and electric dipole moments. Within the MSSM also the lightest Higgs-boson mass, M_h, is discussed as a precision observable. The EWPO, supplemented with B physics observables and astrophysical data can be used to determine indirectly the preferred mass scales of Supersymmetry and M_h.
