Hi Sean,</div>
<div class="x_elementToProof" style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Yes, it's important to make sure you get the polarization factors right. It is possible to have some corrections that are polarization dependent and others that are only helicity correlated. In the paper David cited, for example, the helicity-correlated corrections
include asymmetries from beam position, angle and charge between helicity states which are not functions of polarization and thus require subtraction without the 1/P enhancement. It looks like all the backgrounds you are including are, in fact, polarization
dependent and require the 1/P factor you show.</div>

<div dir="ltr">Hi David,
<div><br>
</div>
<div>This is great, thank you! I repeated the calculation, with the result highlighted at the end. The only difference I find is the polarization factors come in differently, but I assume this is just a factor from the different experiments.</div>
<div><br>
</div>
<div>Going forward I would like to use this formalism, so if any GEN experts have any objections to it please let me know before I get too deep in.</div>
