    5858then one can interpret the full propagator in Eq. 3 as the sum of propagators (or interfering graphs) for a collection of particles {{{$V_\lambda$}}}, where each {{{$V_\lambda$}}} has its own propagator.

     65==== ZPolar ====
     66* The {{{SM_Loop_ZPolar}}} UFO contains the SM Lagrangian and includes QCD counter terms up to NLO in QCD. (This means it can be used for both tree-level computations and loop-level computations up to one loop in QCD.) Importantly, the SM Z boson has been replaced with the longitudinal state {{{Z0}}}, the transverse state {{{ZT}}}, the auxiliary state {{{ZA}}}, and the unpolarized state {{{ZX}}}. The state {{{ZX}}} is essentially the original Z boson.
     67 - The PIDs are: 23 for {{{ZX}}}, 230 for {{{Z0}}}, 231 for {{{ZT}}}, and 232 for {{{ZA}}}
     68 - The W boson is '''NOT''' polarized in this UFO
     69 - ~/Path $ wget http://feynrules.irmp.ucl.ac.be/raw-attachment/wiki/VPolarization/SM_Loop_ZPolar.tgz ./
     70 - ~/Path $ tar -zxvf SM_Loop_ZPolar.tgz
    6571
     72==== WPolar ====
     73* The {{{SM_Loop_WPolar}}} UFO is like {{{SM_Loop_ZPolar}}} but for the W boson
     74 - The PIDs are: +24 for {{{WX^+}}}, +240 for {{{W0^+}}}, +241 for {{{WT^+}}}, and +242 for {{{WA^+}}}
     75 - For the W^- fields, use the {{{-PID}}}
     76 - The Z boson is '''NOT''' polarized in this UFO

    6679
     80==== LO UFOs ====
     81* The {{{SM_WPolar_XLO}}} and {{{SM_ZPolar_XLO}}} UFOs are like the two UFOs above but '''DO NOT CONTAIN''' QCD counter terms
     82 - ~/Path $ wget http://feynrules.irmp.ucl.ac.be/raw-attachment/wiki/VPolarization/SM_WPolar_XLO.tgz ./
     83 - ~/Path $ wget http://feynrules.irmp.ucl.ac.be/raw-attachment/wiki/VPolarization/SM_ZPolar_XLO.tgz ./

     85* The {{{SM_VPolar_XLO}}} UFO contains both polarized W and Z bosons but '''DOES NOT CONTAIN''' QCD counter terms
