Unitarity Cuts with Massive Propagators and Algebraic Expressions for Coefficients
In the first part of this paper, we extend the d-dimensional unitarity cut method of hepph/0609191 to cases with massive propagators. We present formulas for integral reduction with which one can obtain coefficients of all pentagon, box, triangle and massive bubble integrals. In the second part of this paper, we present a detailed study of the phase space integration for unitarity cuts. We carr...
متن کاملResearch Universities: Core of the US science and technology system
Research universities are a recent innovation, having emerged in Prussia in the early 19th century, and in the United States only in the aftermath of the Civil War. By 1940, perhaps a dozen American universities could be regarded as firstclass research institutions. However, they received virtually no financial support from the US government.

متن کاملPolicies on faculty conflicts of interest at US universities.
CONTEXT Despite federal regulations on faculty conflicts of interest in federally funded research, academic-industry ties are common, and evidence exists that financial considerations bias the research record. Public scrutiny of these ties is increasing, especially in cases where researchers have financial interests in the corporate sponsors of their clinical research. OBJECTIVE To review pol...
