The recent ASACUSA publication “Measurement of the principal quantum number distribution in a beam of antihydrogen atoms” by B. Kolbinger et al. https://doi.org/10.1140/epjd/s10053-021-00101-y has been chosen by the European Physical Journal D for the front page of its March 2021 issue https://epjd.epj.org/articles/epjd/abs/2021/03/contents/contents.html. An earlier article ”Induced THz transitions in Rydberg caesium atoms for application in antihydrogen experiments” by T. Wolz et al. https://doi.org/10.1140/epjd/s10053-020-00013-3, co-authored by ASACUSA members, appeared on the front page of the EPJD January 2021 issue https://epjd.epj.org/articles/epjd/abs/2021/01/contents/contents.html. Both appearances signify a remarkable feature of the work of our collaboration.
