The exclusive rare decay b->s gamma of heavy b-Baryons

We present an analysis on the exclusive rare radiative decay modes Sigma_b->Sigma gamma and Xi_b->Xi gamma. The transition form factors which parameterize these processes are calculated using QCD light-cone sum rules. The decay widths we predict are Gamma(Sigma_b->Sigma gamma)=(7.21\pm0.04)\times10^{-18}GeV} and Gamma(Xi_b->Xi gamma)=(1.34\pm0.07)\times10^{-16}GeV. The Branching ratio of Xi_b->Xi gamma is predicted to be Br(\Xi_b->Xi gamma)=(3.03\pm0.10)\times10^{-4}.Comment: 10 pages, 4 figures; to appear in Phys. Rev.

The Application Of The IoT For Minimizing Consumption In Smart Home

Excessive consumption leads to 7 trends of crises, including destruction of the atmosphere, energy crisis, social decline and conflicts. Over consumption also deteriorates human health. To reduce excessive consumption not only can improve health, it can also secure home safety and less energy consumption. The reducing over consumption can benefit human health and environmental protection. This motivates us to devise an innovative smart home App (SHA). After a survey to potential users, it reveals that the new features can help reduce the excessive consumption and deterioration of the human health as well as the transportation, healthcare and destruction of earth environment. Enterprises can also achieve their social responsibility through the implementation and popularization of the SHA as soon as possible
