## Description of the model:

This is a Contact Interaction (CI) model.

The lagrangian of the model is described by:

At the first model, only the off-diagonal elements for the b-s admixtures are considered, since those are the ones related to the observed b-s-l-l anomalies. The matrices take the form:

A more general model is also attached, contains the full terms: #!latex \begin{eqnarray} C_{ij}{U \mu} = \begin{pmatrix} C_{u \mu} & 0 & 0
0 & C_{c \mu} & 0
0 & 0 & C_{t \mu} \end{pmatrix} , C_{ij}
{D \mu} = \begin{pmatrix} C_{d \mu} & 0 & 0
0 & C_{s \mu} & C_{b s \mu}{*}
0 & C_{b s \mu} & C_{t \mu} \end{pmatrix} \end{eqnarray} }}}

Similar couplings to electrons are considered as well for complicity.
