Description

In this lecture I will discuss a method of morphing distributions
that is useful to measure the parameters of an Effective Field
Theory (EFT). I will introduce EFT which is a powerful
theoretical framework that is used to systematically extend
known physics lagrangians. I will then talk about the idea
behind the morphing between distributions given the
predictions at some point in the parameter space which allow
to obtain a continuous prediction in terms of EFT parameters.
I will finally show a couple of examples of the implementation
of this technique as the RooLagrangianMorphFunc class
within RooFit toolkit that is available with the ROOT software.
