rho
Definition of angles in the process eN -> e\rho^{0}N->e\pi^{+}\pi^{-}N. Here, \PHI is the angle between the \rho^{0} production plane and the lepton scattering plane in the CM system of virtual photon and target nucleon. The variables \theta and \phi are respectively the polar and azimuthal angles of the decay \pi^{+} in the \rho^{0}-meson rest frame, with the z axis being anti-parallel to the outgoing nucleon momentum. The XZ and xz planes both the \gamma^{\star} and \rho^{0} three-momenta

VECTOR-MESONS
asymmetry, omega
The five amplitudes describing the strength of the sine modulations of the cross section for hard exclusive omega meson production. The full circles show the data in two bins of Q^{2} or -t^{\prime}. The open squares represent the results obtained for the entire kinematic region. The inner error bars represent the statistical uncertainties, while the outer ones indicate the statistical and systematic uncertainties added in quadrature. The results receive an additional 8.2% scale uncertainty corresponding to the target-polarization uncertainty. The solid (dash-dotted) lines show the calculation of the GK model for a positive (negative) \pi\omega transition form factor, and the dashed lines are the model results without the pion pole

Also shown in the top panel is the previously published spectrum from 1998-2000 of data that has been reanalyzed here. A Voigtian (using a Gaussian with a width fixed to 6 MeV) together with two different background hypotheses was fitted to the summed spectrum in the bottom panel. The resulting curves are shown separated into signal and background contribution and also combined. The width \Gamma of the Breit-Wigner function, the peak position M, and the number of signal events obtained from the fits are given in the panel

The strange-parton distribution xS (x, Q2 ) from the measured HERMES multiplicity for charged kaons evolved to Q2 = 2.5 GeV2 assuming \int DSK (z, Q2)dz = 1.27. The solid curve is a two-parameter fit with S(x)=(\int DSK (z, Q2)dz)^-1 x^{-0.867\pm0.019} e^{-x/(0.0331\pm0.0014)} (1-x). The dashed, dot-dash, dotted curves are as given in Fig. 2. The broad band is the \pm 1 sigma zone of allowed values predicted by the neural network (NNPDF2.3) reference set [14]. The band at the bottom represents the propagated experimental systematic uncertainties. A scale uncertainty of approximately 10% coming from the precision of \int DSK (z, Q2)dz is not shown

The strange-parton distribution xS(x,Q2) from the measured HERMES multiplicity for charged kaons evolved to Q2 = 2.5 GeV2 using the compilation of fragmentation functions (FFs) from [9] (DSS). The solid curve is a three-parameter fit to the data, the dashed curve gives xS(x) from CTEQ6L, and the dot-dash curve is the sum of light anti-quarks from CTEQ6L. The dotted curve is from CTEQ 6.5 S-0, a PDF reference set [10] in which the shape of xS(x) has not been constrained. The band containing the experimental points represents the fully correlated systematic uncertainties arising from the imprecision of \int DQK (z, Q2)dz

The multiplicity of charged kaons in semi-inclusive DIS from a deuterium target, as a function of Bjorken x. The continuous curve is calculated from the strange-quark contribution taken from the fit in Fig. 3, together with the non-strange contribution as extracted from the high-x multiplicity data (see text). The green dashed (magenta dash-dotted) curve shows separately the nonstrange- (strange-) quark contribution to the multiplicity for that fit. The blue-dotted curve is the LO prediction obtained with CTEQ6L PDFs and fragmentation functions from [9]. The values of the average Q2 for each x bin are shown in the lower panel. The band represents systematic uncertainties

Amplitudes of single-charge beam-helicity asymmetry extracted from pure sample obtained with recoil-proton reconstruction. The amplitudes are presented in projections of -t, xB, and Q2. The overall results shown in the very left panel are extracted in a single kinematic bin covering the entire kinematic acceptance. Statistical (systematic) uncertainties are represented by error bars (bands). A separate scale uncertainty arising from the measurement of the beam polarization amounts to 1.96%. The theoretical models are evaluated at the average values of the kinematics. The thickness of the VGG lines represents the range bval = 1...infinity

Amplitudes of single-charge beam-helicity asymmetry in DVCS shown in projections of -t, xB, and Q2. Statistical uncertainties are shown by error bars. The bands represent the systematic uncertainties of the amplitudes extracted from the pure sample. A separate scale uncertainty arising from the measurement of the beam polarization amounts to 1.96%. Shown are amplitudes extracted from a) the pure sample (red circles, shown at their kinematic values), i.e., obtained with recoil-proton reconstruction; b) the unresolved-reference sample (blue triangles, shifted to the right for better visibility), i.e., without recoil-proton reconstruction but requiring its four-momentum to be in the recoil-detector acceptance; c) the unresolved sample (black stars, shifted to the left for better visibility), i.e., without requirements from recoil-detector acceptance and reconstruction. The latter two sets of amplitudes are subject to an average contribution of 14% and 12%, respectively, for associated processes

Results from the present work (red filled squares) representing single-charge beam-helicity asymmetry amplitudes describing the dependence of the sum of squared DVCS and interference terms on the beam helicity, for a tensor polarization of Pzz=0.827 . The black open squares represent charge-difference amplitudes from only the interference term, extracted from unpolarized deuterium data. The error bars represent the statistical uncertainties, while the coarsely hatched (open) bands represent the systematic uncertainties of the filled (open) squares. There is an additional overall 1.9% (2.4%) scale uncertainty arising from the uncertainty in the measurement of the beam polarization in the case of polarized (unpolarized) deuterium data. The points for unpolarized deuterium data are slightly shifted to the left for better visibility. The finely hatched band shows the results of theoretical calculations for the combination of incoherent scattering on proton and neutron, using variants of the VGG double-distribution model with a Regge ansatz for modeling the t dependence of GPDs

The error bars (open red bands) show the statistical (systematic) uncertainties and the solid blue bands represent the theoretical predictions from the ``VGG Regge'' GPD model. There is an additional 5.3% scale uncertainty due to the precision of the measurement of the beam and target polarisations. The fractional contributions from resonance production estimated from an MC model are presented in the bottom panel

Virtual photon Collins moments for charged pions as function of x, z and $P_{h\perp}$ compared to theoretical curves from [Efremov et al. hep-ph/0603054]. For the x-dependence the data are fitted using always a gaussian ansatz and a cQSM for the transversity function from [PRD64(2001),034013] to obtain a value for the favoured and unfavoured Collins ff (Eqn. 10 and 11 in hep-ph/0603054). In contrast, for the z dependence the curves are based on a fit of the Collins ff to the BELLE data and on the same cQSModel for the transversity function. The light shaded area indicates the sensitivity of the SSA to the unknown ratio of the gaussian width of h1 and H1^\perp

The relative size of the lepton (dashed line) and hadron distributions (solid line) was scaled to the flux ratio in the respective data--taking periods to give a better idea of the level of contamination possible from each detector.

The left figure shows the range for recombination and the right picture shows the range for wall depolarization. Acceptable uncertainties of $\alphar$ and $\depol_{WD}$ (differences among the three horizontal dotted lines) can be achieved only with $\alphar^{TGA}$ and $\depol_{WD}^{BRP}$ close to unity (vertical dotted lines).

Inner errorbars represent the statistical uncertainty and outer errorbars the quadratic sum of statistical and systematic uncertainties. The latter contains the uncertainty due to the correction for radiative and smearing effects. The systematic error from RICH unfolding is shown as a symmetric yellow band (for the VMD corrected data set only). The data is evolved to a common Q2=2.5 GeV2

The open triangles ($^{12}$C) and crosses ($^{4}$He) have been derived from the NMC data using Eq.~3. The other SLAC and NMC data displayed have been derived from published values of $\Delta R = RA - RD$ and a parameterisation for $RD$. The inner error bars represent the statistical uncertainty and include the correlated error in $F2A/F2D$. The outer error bars represent the quadratic sum of the statistical and systematic uncertainties. In the upper panel the HERMES results at the lowest $Q2$ value have been suppressed because of its large error bar
