[打听] “W粒子质量” VS “标准模型”,谁出问题了?

FIG. 5. Comparison of this CDF II measurement and past MW measurements with the SM expectation.

The latter includes the published estimates of the uncertainty (4 MeV) due to missing higher-order quantum corrections, as well as the uncertainty (4 MeV) from other global measurements used as input to the calculation, such as mtc, speed of light in a vacuum.

请教:下面图里哪个象限是对的?

   “W粒子质量”或“标准模型”,谁出问题了?

   标准模型对,但依据该理论的“W玻色子质量”理论计算错误?
