Evidently ATLAS listed its members alphabetically and CMS listed them by some other criterion (maybe seniority?). However, I would guess that ATLAS got its member list first in the paper by being the alphabetically prior of the two collaborations (!).

So, that suggests that you should not only change your name to Aaalweachter, but also be sure to work on the AARDVARK research collaboration. (Or found one if it doesn't already exist.)
