A template method to measure the [Formula omitted] polarisation

We develop a template method for the measurement of the polarisation of [Formula omitted] pairs produced in hadron collisions. The method would allow to extract the individual fractions of [Formula omitted], [Formula omitted], [Formula omitted] and [Formula omitted] pairs with a fit to data, where L, R refer to the polarisation along any axis. These polarisation fractions have not been independently measured at present. Secondarily, the method also provides the net polarisation of t and [Formula omitted], as well as their spin correlation for arbitrary axes.
