Measurement of Charged and Neutral Current e−p Deep Inelastic Scattering Cross Sections at High Q2

M. Derrick, D. Krakauer, S. Magill, D. Mikunas et autres

Deep inelastic ${e}^{\ensuremath{-}}p$ scattering has been studied in both the charged current (CC) and neutral current (NC) reactions at momentum transfers squared ${Q}^{2}$ above $400{\mathrm{GeV}}^{2}$ using the ZEUS detector at the HERA $\mathrm{ep}$ collider. The CC and NC total cross sections, the …

Dijet cross sections in photoproduction at HERA

David Bailey, M. Derrick, D. Krakauer, S. Magill et autres

Dijet production by almost real photons has been studied at HERA with the ZEUS detector. Jets have been identified using the cone algorithm. A cut on xγOBS, the fraction of the photon energy participating in the production of the two jets of …
