Effective Lagrangian Morphing
arxiv(2022)
摘要
With the LHC entering the precision era, focus on interpreting the
measurements performed in an effective field theory holds key to testing the
Standard Model. An effective field theory provides a well-defined theoretical
formalism which extends the Standard Model by introduce new terms with free
coefficients that can be measured with experimental data. Constructing models
parametric in these new coefficients is achieved by virtue of combining
predictions from Monte Carlo generators for different interactions. This paper
builds upon earlier works and describes a state-of-the-art approach to build
multidimensional parametric models for new physics using effective Lagrangians.
Documentation and tutorials for an associated toolkit that have been
contributed to the ROOT data analysis software framework is included.
