Deep inelastic eγ scattering at high Q2

Deep Inelastic Eγ Scattering at High Q

The electromagnetic and weak structure functions of the photon can be studied in the deep inelastic electron-photon processes eγ → e +X and eγ → ν +X. While at low energies only virtual photon exchange is operative in the neutral-current process, additional Z-exchange becomes relevant for high Q of order M Z at e e linear colliders. Likewise the charged-current process can be observed at these ...

Inclusive Deep Inelastic Scattering at High Q2 with Longitudinally Polarised Lepton Beams at HERA

Inclusive e±p single and double differential cross sections for neutral (NC) and charged current (CC) deep inelastic scattering processes are measured with the H1 detector at HERA. The data were taken at a centre-of-mass energy of √ s = 319 GeV with a total integrated luminosity of 327.8 pb−1 shared between two lepton beam charges and two longitudinal lepton polarisation modes. The differential...

High-Q Deep Inelastic Scattering at HERA

High Q NC and CC cross sections as measured at HERA can give information on two distinct areas of current interest. Firstly, supposing that all the electroweak parameters are well known, these cross-sections may be used to give information on parton distribution functions (PDFs) in the new kinematic regime at high x and high Q. Secondly, supposing that PDFs are well known after evolution in Q f...

Deep Inelastic Scattering at HERA

Inclusive production of D(2010) mesons in deep inelastic scattering has been measured using ep and ep data obtained with the ZEUS detector at HERA using integrated luminosities of 16.7 and 65.2pb, respectively. The decay channel D → Dπ with D → Kπ and corresponding antiparticle decays were used to identify D mesons. The D cross sections in ep and ep interactions agree with NLO QCD predictions, ...
