TUM-HEP-1551/25}, year = {2025}, note = {9 pages + appendix, 6 beautiful figures}, abstract = {We calculate $(\sqrt{-t}/Q)^k $ and $(m/Q)^k$ power corrections with $k\le 4$, where $m$ is the target mass and $t$ is the momentum transfer, to several key observables in Deeply Virtual Compton Scattering (DVCS). We find that the power expansion is well convergent up to $|t|/Q^2\lesssim 1/4$ for most of the observables, but is naturally organized in terms of $1/(Q^2+t)$ rather than the nominal hard scale $1/Q^2$. We also argue that target mass corrections remain under control and do not endanger QCD factorization for coherent DVCS on nuclei. These results remove an important source of uncertainties due to the frame dependence and violation of electromagnetic Ward identities in the QCD predictions for the DVCS amplitudes in the leading-twist approximation.}, cin = {UNI/TH}, cid = {$I:(DE-H253)UNI_TH-20120731$}, pnm = {611 - Fundamental Particles and Forces (POF4-611) / DFG project G:(GEPRIS)409651613 - FOR 2926: Next Generation Perturbative QCD for Hadron Structure: Preparing for the Electron-Ion Collider (409651613)}, pid = {G:(DE-HGF)POF4-611 / G:(GEPRIS)409651613}, experiment = {EXP:(DE-MLZ)NOSPEC-20140101}, typ = {PUB:(DE-HGF)25}, eprint = {2501.08185}, howpublished = {arXiv:2501.08185}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:2501.08185;\%\%$}, doi = {10.3204/PUBDB-2025-00063}, url = {https://bib-pubdb1.desy.de/record/620185}, }
