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...

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 ...

The Exclusive Decay B → ρeν Beyond Model Calculations

Due to its comparatively theoretical “simplicity”, the decay channel B → ρeν offers one of the best possibilities to determine the CKM matrix element |Vub| accurately. I present a new calculation of the relevant hadronic form factors from light-cone sum rules. I also review the results from lattice calculations and find that they agree with the results from light-cone sum rules where comparison...

Systematics and Limit Calculations

This note discusses the estimation of systematic uncertainties and their incorporation into upper limit calculations. Two different approaches to reducing systematics and their degrading impact on upper limits are introduced. An improved χ function is defined which is useful in comparing Poisson distributed data with models marginalized by systematic uncertainties. Also, a technique using profi...
