Rapidity divergences and deep inelastic scattering in the endpoint region
Rapidity divergences and deep inelastic scattering in the endpoint region
The deep inelastic scattering cross section in the endpoint region $x\ensuremath{\sim}1$ has been subjected to extensive analysis. We revisit this process using soft collinear effective theory, and show that in the endpoint individual factors in the factorized hadronic tensor have rapidity divergences. We regulate these divergences using a recently introduced …
