“…The circles represent the data points and the curves show the predictions of the SM evaluated using the HERAPDF1.0, ZEUS-JETS, CTEQ6.6 and MSTW2008 PDFs. The dashed lines show the contributions of the PDF combination x(ū +c) and the shaded band shows the total uncertainty from the HERAPDF1.0 PDFs ing previous ZEUS measurements from both e − p and e + p data [11,12,14] and previous H1 measurements from e + p data [7]. The H1 measurements were scaled to the kinematic region of this analysis.…”

“…Using data taken at the HERA ep collider in the years 1993-2000 and 2004-2006, the H1 and ZEUS collaborations have reported measurements of the cross sections for CC DIS [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. These measurements extend the kinematic region covered by fixed-target proton-structure measurements [15][16][17][18] to higher values of negative four-momentumtransfer squared, Q 2 .…”

Measurements of the cross sections for charged current deep inelastic scattering in e + p collisions with a longitudinally polarised positron beam are presented. The measurements are based on a data sample with an integrated luminosity of 132 pb −1 collected with the ZEUS detector at HERA at a centre-of-mass energy of 318 GeV. The total cross section is presented at positive and negative values of the longitudinal polarisation of the positron beams. dσ/dy are presented for Q 2 > 200 GeV 2 . The reduced cross-sectionσ is presented in the kinematic range 200 < Q 2 < 60 000 GeV 2 and 0.006 < x < 0.562. The measurements agree well with the predictions of the Standard Model. The results are used to determine a lower limit on the mass of a hypothetical right-handed W boson.

The LHeC is a proposed upgrade of the LHC to study ep/eA collisions in the TeV regime, by adding a 60 GeV electron beam through an energy recovery linac. In ep, high precision top and electroweak physics can be performed, such as measurements of anomalous top couplings, light quark couplings to the Z boson and the energy dependence of the weak mixing angle sin 2 θ W , for which simulation studies are presented.

“…With the advent of longitudinally polarised lepton beams in collider mode, in HERA II, it became possible to directly measure the polarisation dependence of charged current DIS. The result [199,201,202] is shown in Figure 37. Within the standard model, G F is a function of the fine structure constant, α, the masses of the gauge bosons M W and M Z .…”
