The azimuthal correlation between the leading jet and the scattered lepton in deep inelastic scattering at HERA
Published 2024-12-01“…Differential cross sections, $$d\sigma /d\Delta \phi $$ d σ / d Δ ϕ , were measured as a function of the azimuthal correlation angle in various ranges of leading-jet transverse momentum, photon virtuality and jet multiplicity. Perturbative calculations at $$\mathcal {O}(\alpha _{s}^2)$$ O ( α s 2 ) accuracy successfully describe the data within the fiducial region, although a lower level of agreement is observed near $$\Delta \phi \rightarrow \pi $$ Δ ϕ → π for events with high jet multiplicity, due to limitations of the perturbative approach in describing soft phenomena in QCD. …”
