HOCTOOLS NNLO meeting

17 Jan 2015, 08:00 → 18 Jan 2015, 18:00 Europe/Athens

Other Institutes

The Athens NNLO meeting will be held in NCSR-Demokritos, Athens, Greece, January 17-18, 2015. The purpose of the meeting is to bring together world-wide experts in NNLO calculations, in order to review the state of the art in the field and discuss the short- and medium-term perspectives towards a general automation of the NNLO calculations.

Topics include:

- Integrand and integral level reduction methods at two loops

- New methods for the calculation of Master Integrals, differential and IBP equations

- Real corrections for NNLO calculations

- Available computational tools

The meeting is organised in the framework of the Research Funding Program “ARISTEIA”, “Higher Order Calculations and Tools for High Energy Colliders”, HOCTools, co-financed by the European Union (European Social Fund ESF) and Greek national funds through the Operational Program “Education and Lifelong Learning” of the National Strategic Reference Framework (NSRF).
