The CMS High Level Trigger
The CMS Trigger, Data Acquisition Group
At the Large Hadron Collider at CERN the proton bunches cross at a rate of 40MHz. At the Compact Muon Solenoid experiment the original collision rate is reduced by a factor of O (1…
Steady state entanglement in open and noisy quantum systems at high temperature
L. Hartmann, W. Dür, H. -J. Briegel
We show that quantum mechanical entanglement can prevail even in noisy open quantum systems at high temperature and far from thermodynamical equilibrium, despite the deteriorating…
On the estimate of the sigma^(I = 1)_(KN)(0)-term value from the energy level shift of kaonic hydrogen in the ground state
A. N. Ivanov, M. Faber, V. A. Ivanova +2
Using the experimental data on the energy level shift of kaonic hydrogen in the ground state (the DEAR Collaboration, Phys. Rev. Lett. 94, 212302 (2005)) and the theoretical value…
Supersymmetry Parameter Analysis: SPA Convention and Project
J. A. Aguilar-Saavedra, A. Ali, B. C. Allanach +122
High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is…
Nonlinear entanglement witnesses
Otfried Gühne, Norbert Lütkenhaus
Entanglement detection typically relies on linear inequalities for mean values of certain observables (entanglement witnesses), where violation indicates entanglement. We provide a…
Evidence for Efimov quantum states in an ultracold gas of cesium atoms
T. Kraemer, M. Mark, P. Waldburger +8
Systems of three interacting particles are notorious for their complex physical behavior. A landmark theoretical result in few-body quantum physics is Efimov's prediction of a univ…
