==== Usage resources ====

* For instructions and examples on using the VPolar UFO libraries, see M. Javurkova, et al, arXiv:xxx.yy [ [#Javurkova 1] ]
* For additional background, see also D. Buarque Franzosi, et al, arXiv:1912.01725 [ [#BuarqueFranzosi 2] ]
* See '''Validation''' section below for additional information

* '''Special note:''' this UFO was developed using MG5aMC and calls the '''1L''', '''1T''', and '''1A''' propagators defined in ALOHA (see '''aloha_object.py''' and ''create_aloha.py''). These may be defined differently in other generators. If they are not defined in your favorite generators, they must be added to the ''propagators.py'' file in the {{{VPolar}}} UFO. The file '''particles.py''' must then be updated to reflect the propagator names. R. Ruiz is happy to assist with this.
