Photon–jet correlations in deep-inelastic scattering

European Physical Journal C: Particles and Fields, 2017
The reaction $$e + p \rightarrow \gamma + \mathrm{jet} + X$$ e + p → γ + jet + X is studied in QCD at the next-to-leading order. Previous studies on inclusive distributions showed good agreement with ZEUS data.

Test of the TMD gluon density in a proton with the longitudinal structure function FL(x,Q2)

Physics Letters B, 2023
We investigate the dependence of the deep inelastic proton structure function FL(x,Q2) on different forms of the transverse momentum dependent (TMD, or unintegrated) gluon distribution.

Confinement and scaling in deep inelastic scattering [PDF]

Physical Review D, 1995
We show that parton confinement in the final state generates large $1/Q^2$ corrections to Bjorken scaling, thus leaving less room for the logarithmic corrections. In particular, the $x$-scaling violations at large $x$ are entirely described in terms of power corrections.

Transverse Momentum in Semi-Inclusive Polarized Deep Inelastic Scattering and the Spin-Flavor Structure of the Proton [PDF]

, 2002
The non-valence spin-flavor structure of the nucleon extracted from semi-inclusive measurements of polarized deep inelastic scattering depends strongly on the transverse momentum of the detected hadrons which are used to determine the individual ...

Azimuthal correlations in photoproduction and deep inelastic ep scattering at HERA

Journal of High Energy Physics, 2021
Collective behaviour of final-state hadrons, and multiparton interactions are studied in high-multiplicity ep scattering at a centre-of-mass energy s $$ \sqrt{s} $$ = 318 GeV with the ZEUS detector at HERA.

Isolated Photons in Deep Inelastic Scattering [PDF]

Physical Review Letters, 2006
Photon radiation at large transverse momenta at colliders is a detailed probe of hard interaction dynamics. The isolated photon production cross section in deep inelastic scattering was measured recently by the ZEUS experiment, and found to be considerably larger than theoretical predictions obtained with widely used event generators.

Deep inelastic scattering in conformal QCD [PDF]

Journal of High Energy Physics, 2010
We consider the Regge limit of a CFT correlation function of two vector and two scalar operators, as appropriate to study small-x deep inelastic scattering in N=4 SYM or in QCD assuming approximate conformal symmetry. After clarifying the nature of the Regge limit for a CFT correlator, we use its conformal partial wave expansion to obtain an impact ...

Measurement of Gamma-Ray from Inelastic Neutron Scattering on 56Fe [PDF]

EPJ Web of Conferences, 2020
In nuclear reactors, inelastic neutron scattering is a significant energy-loss mechanism which has deep impacts on designments of nuclear reactor and radiation shielding. Iron is an important material in reactor.
