Science Beyond Calculations

[Science beyond calculations].

Beyond climate science.

THE UNITED STATES IS MOVING RAPIDLY INTO AN AGE OF CLIMATE-RELATED DECISIONS INVOLVING mitigation and adaptation, following decades of focusing on reducing uncertainties in attribution and prediction. But the nation lacks a deliberate approach to generating the “environmental intelligence” needed to support good decisions. It is critical to create a single, credible, authoritative source of cli...

Beyond neutral science.

Biodiversity science is unusual in that an emerging paradigm is not based on a specific process, but rather depends largely on stochastic elements, perceived as neutral forces. Here I suggest that these forces, which have been justified, in part, by the concepts of symmetry and equalizing mechanisms, have application to the understanding of stochastic models but do not constitute forces that op...

Beyond standard model calculations with Sherpa

We present a fully automated framework as part of the Sherpa event generator for the computation of tree-level cross sections in Beyond Standard Model scenarios, making use of model information given in the Universal FeynRules Output format. Elementary vertices are implemented into C++ code automatically and provided to the matrix-element generator Comix at runtime. Widths and branching ratios ...

Matrix model calculations beyond the spherical limit

We propose an improved iterative scheme for calculating higher genus contributions to the multi-loop (or multi-point) correlators and the partition function of the hermitian one matrix model. We present explicit results up to genus two. We develop a version which gives directly the result in the double scaling limit and present explicit results up to genus four. Using the latter version we prov...
