Threshold photo-production of J/Ψ off light nuclei
Jul 13, 2024Citations per year
Abstract: (arXiv)
We analyze threshold photoproduction of heavy mesons off a deuteron and Helium-4, using the QCD factorization method. Assuming large skewness, the production amplitude is dominated by the leading twist-2 gluonic energy-momentum tensor (EMT). We use our recent results for the gluonic gravitational form factors of light nuclei in the impulse approximation, to estimate the differential cross sections for J/Ψ production off a deuteron and Helium-4 at current electron facilities.Note:
