Description

As a physicist devoted to medical physics research, I've never fitted a Higgs search plot nor run worldwide distributed analysis of data taken at CERN. Unexpectedly, I am heavy user of ROOT, however for more mundane applications related to my research with high count rate radiation detectors, as well as for teaching, at a small laboratory within CSIC/University of Valencia.
Thus, I would like to present the view on ROOT from outside the CERN ecosystem, a potentially much larger user base. I will highlight the key strengths of ROOT for this kind of community, the main hurdles discouraging its cheerful adoption by newbie students, and identify the main aspects that I consider a priority to improve.
Naturally, these might not align with the priorities in the HEP software roadmap. However, I consider that a broad adoption of ROOT and finding a balance between inside-CERN versus outsider support pays back: it increases the likelihood of bug detection, feedback and number of contributors volunteering to improve this excellent open-source software.
