Computations in Theoretical Physics: Techniques and Methods

Oral

The best way to search for new physics is by using a diverse set of probes - not just experiments at the energy and the cosmic frontiers, but also the low-energy measurements relying on high precision and high luminosity. One example of ultra-precision experiments is MOLLER planned at JLab, which will measure the parity-violating electron-electron scattering asymmetry and allow a...

Computations in Theoretical Physics: Techniques and Methods

Oral

We present an automated software tool "SModelS" to systematically confront theories Beyond the Standard Model (BSM) with experimental data. The tool consists of a general procedure to decompose such BSM theories into their Simplified Model Spectra (SMS). In addition, SModelS features a database containing the majority of the published SMS results of CMS and ATLAS. These SMS...

181. Making extreme computations possible with virtual machines

Computations in Theoretical Physics: Techniques and Methods

Oral

State-of-the-art algorithms generate scattering amplitudes for high-energy physics at leading order for high-multiplicity processes as compiled code (in Fortran, C or C++). For complicated processes the size of these libraries can become tremendous (many GiB). We show that amplitudes can be translated to byte-code instructions, which even reduce the size by one order of magnitude. The...

225. High Performance and Increased Precision Techniques for Feynman Loop Integrals

Computations in Theoretical Physics: Techniques and Methods

Oral

For the investigation of physics beyond and within the Standard Model, the precise evaluation of higher order corrections in perturbative quantum field theory is required. We have been developing a computational method for Feynman loop integrals with a fully numerical approach. It is based on a numerical integration techniques and an extrapolation. In this presentation, we describe the...
