Three - loop matching of the dipole operators for b → sγ and b → sg
We evaluate the three-loop matching conditions for the dimension-five operators that are relevant for the b → sγ decay. Our calculation completes the first out of three steps (matching, mixing and matrix elements) that are necessary for finding the next-to-next-to-leading QCD corrections to this process. All such corrections must be calculated in view of the ongoing accurate measurements of the...
متن کاملTwo - loop matching of the dipole operators for b → sγ and b → sg 1 Christoph
The order αs corrections to the Wilson coefficients of the dipole operators (O7, O8) at the matching scale μ = mW are a crucial ingredient for a complete next-to-leading logarithmic calculation of the branching ratio for b → sγ. Given the phenomenological relevance and the fact that this two-loop calculation has been done so far only by one group [1], we present a detailed re-calculation using ...

15 صفحه اولsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
