Dear colleagues,

I am writing to you regarding your abstracts submitted to WG1: Structure Functions and Parton Densities at DIS2022 in Santiago de Compostela. As you may be aware, being one of the first in person conferences in a long time, we have received an extraordinary number of abstract submissions. As a result, we are writing to ask you if it might be possible to merge two of the abstracts submitted by yourselves and colleagues of yours.  The abstracts we refer to are "Gluon distributions in light mesons on the light front" (abstract number 168, to be presented by Jiangshan Lan with coauthors Kaiyu Fu, Chandan Mondal, Xingbo Zhao, James Vary) and "Heavy mesons with one gluon on the light front" (abstract number 201, to be presented by Jiatong Wu with coauthors Hengfei Zhao, Kaiyu Fu, Jiangshan Lan, Xingbo Zhao, James Vary), given the shared authors we hope these could be merged. Please share this email with your collaborators and let us know if this would be fine for you as the authors as soon as possible and thanks in advance for your understanding. We would also ask you to confirm that a member of your collaboration would be able to attend to give the talk at Santiago in person.

Many thanks,

Tom Cridge on behalf of the WG1 conveners (Tom, Barak, Klaus)
