In the context of high-energy particle physics, the Large Hadron Collider (LHC) and the planned future colliders [1,2,3,4,5,6,7,8] will keep on reducing the experimental uncertainties, forcing to reach a compatible accuracy level from the theory side. However, there are huge bottlenecks ...
Their observation, that often those who have to communicate a scientific result or make public decisions are convinced that the clarification of uncertainties can produce negative consequences [92], is relevant when dealing with radon. The psychological dimension occupies a prominent place, since it ...
3,17,18,19,20. These approaches are useful for problems in which the structure of the governing equations is known and the uncertainties are strictly parametric. Although model-free state-estimation techniques can be used in situations in which dynamics are unknown4,23,24,25, these ...
Within the uncertainties, all these observations are compatible with the predictions of the standard model of elementary particle physics. Much evidence points to the fact that the standard model is a low-energy approximation of a more comprehensive theory. Several of the standard model issues ...
Active cooling of the engine called for resolution of “major uncertainties…connected with supersonic burning.” In approaching these issues, “very great uncertainties exist at a fundamental level.” 国防科学委员会(DSB)还包括了对X-30飞行控制及其发动机控制问题的强烈关注。这些都不是简单的使用副翼或...
2.2. Include the absolute uncertainties in T 2 . [3] (c) (i) Plot a graph of T 2 / s 2 against l / cm. Include error bars for T 2 . [2] (ii) Draw the straight line of best fit and a worst acceptable straight line on your graph. Both lines should be clearly labelled. [...
Theoretical predictions are slightly larger than the measured cross section but are in agreement within the uncertainties, as depicted in Fig. 6. Fig. 6 Comparison of the experimental measurement of \sigma (\textrm{W}+\textrm{c}), unfolded to the parton level, with the predictions from the ...
