Fragmentation Functions at Next-to-Next-to-Leading Order Accuracy
Daniele P. Anderle, Felix Ringer, Marco Stratmann
We present a first analysis of parton-to-pion fragmentation functions at next-to-next-to-leading order accuracy in QCD based on single-inclusive pion production in electron-positro…
Unveiling the Proton Spin Decomposition at a Future Electron-Ion Collider
Elke C. Aschenauer, R. Sassot, M. Stratmann
We present a detailed assessment of how well a future Electron-Ion Collider could constrain helicity parton distributions in the nucleon and, therefore, unveil the role of the intr…
The RHIC SPIN Program: Achievements and Future Opportunities
Elke-Caroline Aschenauer, Alexander Bazilevsky, Markus Diehl +21
Time and again, spin has been a key element in the exploration of fundamental physics. Spin-dependent observables have often revealed deficits in the assumed theoretical framework…
