During 2010 the LHC delivered pp collisions with a centre-of-mass energy of 7 TeV.In this paper, the results of comprehensive studies of missing transverse energy as measured by the CMS detector are p...
Measuring Gravito-magnetic Effects by Multi Ring-Laser Gyroscope
Gravito-magnetic Ring-Laser
2011/9/15
We propose an under-ground experiment to detect the general relativistic e ects due to the curvature of space-time around the Earth (de Sitter e ect) and to rotation of the planet (dragging of the ine...
In this paper we discuss the luminosity determination at the Tevatron. We discuss luminosity measurements by the machine as well as by using the luminosity detectors of the CDF and D0 experiments. We ...
Fast Neutron Detection with 6Li-loaded Liquid Scintillator
