Description
It is conveniently to use a model-independent approach of effective field theory for indirect search of new physics. This approach consists of parametrization of the lagrangian with operators of higher dimensons with some coefficients. If we compare experimental data with Monte Carlo results, it becomes possible to impose an upper limit of the value of coefficients. However, the real value of any coefficient belongs to a continuous spectrum, whereas Monte Carlo modeling can be performed for discrete set of the values of coefficients. In this work the problem of reweighting of kinematic distributions was considered. There was developed a method to get distributions for any value of coefficient using initial distributions, obtained with fixed coefficient value. This method will be employed to get constraints on the values of coefficients.
