Experimental non-local generation of entanglement from independent sources
We experimentally demonstrate a non-local generation of entanglement from two
independent photonic sources in an ancilla-free process . Two bosons (photons)
are entangled in polarization space by steering into a novel interferometer
setup, in which they have never meet each other. The entangled photons are
delivered to polarization analyzers in different sites, respectively, and a
non-local interaction is observed. Entanglement is further verified by the way
of the measured violation of a CHSH type Bell's inequality with S-values of
2.54 and 27 standard deviations. Our results will shine a new light into the
understanding on how quantum mechanics works, have possible philosophic
consequences on the one hand and provide an essential element for quantum
information processing on the other hand. Potential applications of our results
are briefly discussed.Comment: 5 pages, 4 figure
NLO QCD corrections to Single Top and W associated production at the LHC with forward detector acceptances
In this paper we study the Single Top and W boson associated photoproduction
via the main reaction at
the 14 TeV Large Hadron Collider (LHC) up to next-to-leading order (NLO) QCD
level assuming a typical LHC multipurpose forward detector. We use the
Five-Flavor-Number Schemes (5FNS) with massless bottom quark assumption in the
whole calculation. Our results show that the QCD NLO corrections can reduce the
scale uncertainty. The typical K-factors are in the range of 1.15 to 1.2 which
lead to the QCD NLO corrections of 15 to 20 correspond to the
leading-order (LO) predictions with our chosen parameters.Comment: 41pages, 12figures. arXiv admin note: text overlap with
