The t → cH decay width in the standard model.
The t → cH decay width in the standard model. Abstract The t → cH decay width has been computed in the standard model with a light Higgs boson. The corresponding branching fraction has been found to be in the range B(t → cH) ≃ 10 −13 ÷ 10 −14 for M Z ∼ < m H ∼ < 2M W. Our results correct the numerical evaluation usually quoted in the literature. The one-loop flavor-changing transitions, t → cg,...

متن کاملTree and Tundra Cover Anomalies in the Subarctic Forest-Tundra of Northwestern Canada
Factors that may account for subarctic vegetation patterns that are not reconcilable with synoptic climate were sought by reference to data on local climate, soils, parent materials, vegetation, and topography. Where the forest-tundra lies climatically northward, the vegetation transition zone is relatively narrow, and the soils are nutrient-rich, fine-textured loamy Cryosols derived from sedim...
متن کاملA new evaluation of the t → cH decay width in the standard model
A new evaluation of the t → cH decay width in the standard model. Abstract We present a new calculation of the t → cH decay rate in the standard model. We find that the corresponding branching fraction is B(t → cH) ≃ 10 −13 ÷ 10 −14 for M Z ∼ < m H ∼ < 2M W , that is about 6 orders of magnitude less than previously evaluated, and usually quoted in the literature.
متن کاملAn efficient certificateless signcryption scheme in the standard model
Certificateless public key cryptography (CL-PKC) is a useful method in order to solve the problems of traditional public key infrastructure (i.e., large amount of computation, storage and communication costs for managing certificates) and ID-based public key cryptography (i.e., key escrow problem), simultaneously. A signcryption scheme is an important primitive in cryptographic protocols which ...
