Precision luminosity measurements at LHCb [PDF]

Journal of Instrumentation, 2014
Measuring cross-sections at the LHC requires the luminosity to be determined accurately at each centre-of-mass energy root s. In this paper results are reported from the luminosity calibrations carried out at the LHC interaction point 8 with the LHCb ...

Targets for Precision Measurements [PDF]

Nuclear Data Sheets, 2014
The general properties needed in targets (sources) for high precision, high accuracy measurements are reviewed. The application of these principles to the problem of developing targets for the Fission TPC is described. Longer term issues, such as the availability of actinide materials, improved knowledge of energy losses and straggling and the ...

Measuring precision precisely: A dictionary-based measure of imprecision

The Review of International Organizations, 2022
AbstractHow can we measure and explain the precision of international organizations’ (IOs) founding treaties? We define precision by its negative – imprecision – as indeterminate language that intentionally leaves a wide margin of interpretation for actors after agreements enter into force.

A precise measurement of the tau lifetime [PDF]

The European Physical Journal C, 2004
The tau lepton lifetime has been measured with the e+e- -> tau+tau- events collected by the DELPHI detector at LEP in the years 1991-1995. Three different methods have been exploited, using both one-prong and three-prong tau decay channels. Two measurements have been made using events in which both taus decay to a single charged particle.

On the precision of a length measurement [PDF]

The Logic of Nature, Complexity and New Physics, 2008
We show that quantum mechanics and general relativity imply the existence of a minimal length. To be more precise, we show that no operational device subject to quantum mechanics, general relativity and causality could exclude the discreteness of spacetime on lengths shorter than the Planck length.

High-resolution separation of bioisomers using ion cloud profiling

Nature Communications, 2023
Ion mobility is used in mass spectrometers for structure analysis of biomolecules. Here, the authors show that ion mobility analysis in an ion trap under ultra-high fields enables isomer separation at resolutions over 10,000, wich they demonstrate for ...
