Nature of problem:
The calculation of Electroweak Precision variables for each point of the parameter space of a given beyond the Standard Model theory is tedious and error prone. The available formulas in the literature sometimes contain typos and most of the time they are valid only under some specific conditions, not suitable for quick comparison across different studies nor direct implementation on a computer.
One loop exact calculation of the oblique parameters are collected into a freely available C/C++ library for a number of models. One-loop exact calculation of the contributions of a number of models to the oblique parameters are collected in a freely available C/C++ library. The public availability of the implementations and the internal error checking mechanism aim the correctness of the results. Additionally, the Graphical User Interface and auxiliary tools provide the means for rapid result comparison or update when new data becomes available.
The library computes the oblique parameters S, T and U both with exact one-loop calculations and with well-defined approximations for a number of models to establish a certain level of confidence. The comparisons between exact and approximate computations, and amongst formulas from different papers provide an error checking machinery which improves the end user reliability.
