Because the top quark decays into jets of particles, the top quark mass measurement depends on the jet energy reconstruction. Physicists can calibrate this reconstruction by using the W ... The result of this analysis is the most precise single measurement of the top quark mass so far, truly making it a tip-top analysis.

Accuracy and precision - Wikipedia, the free encyclopedia
In the fields of engineering, industry and statistics, the accuracy of a measurement system is the degree of closeness of measurements of a quantity to its actual (true) value. The precision of a ...

NASA's Wilkinson Microwave Anisotropy Probe (WMAP) has taken the best measurement of the age of the Universe to date. According to highly precise ... Accuracy is a measure of systematic error, which we have no independent means of estimating at this precision (since this is the most precise measurement yet).

SPECIAL COMMUNICATION; Switched single-electrode voltage-clamp amplifiers allow precise measurement of gap junction conductance ... Measurement of gap junction conductance (gj) with patch-clamp amplifiers can, due to series resistance problems, be subject to considerable errors when large currents are measured.

Scientists at Fermilab announced the world's most precise measurement by a single experiment of the mass of the W-boson, the carrier of the weak nuclear force and a key parameter of the Standard Model of particles and forces. ... The CDF result is now the most precise single measurement to date of the W boson mass.
