Abstract：
The indirect estimation of the Higgs Boson mass from electroweak radiative corrections within the Standard Model is compared with the directly measured value obtained by the ATLAS and CMS Collaborations at the CERN LHC collider. Treating the direct measurement of m_H as input, the Standard Model indirect estimation of the top-quark mass is also obtained and compared with its directly measured value. A model-independent analysis finds an indirect value of m_H of ≈ 70 GeV, below the directly measured value of 125.7±0.4 GeV and an indirect value:m_t=177.3±1.0 GeV, above the directly measured value:173.21±0.87 GeV. A goodness-of-fit test to the Standard Model using all Z-pole observables and m_W has a χ² probability of ≈ 2%. The reason why probability values about a factor of ten larger than this, and indirect estimates of m_H about 30 GeV higher, have been obtained in recent global fits to the same data is recalled.
