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 Jun 16, 2017 *Colour (eps) *Colour (pdf) |

16-178 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 Jun 26, 2016 *Colour (eps) *Colour (pdf) *Data |

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 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 Jun 25, 2014 *Colour (eps) *Colour (pdf) *Data |

The product, S(x,Q2)\int DSK (z, Q2)dz, of the strange-quark PDF and the integral of the fragmentation function for strange quarks (squares) obtained from the measured HERMES multiplicity for charged kaons at the average Q2 for each bin. The solid curve is a least-squares fit with the result f(x)=x^{-0.834\pm0.019} e^{-x/(0.0337\pm0.0014)} (1-x). The band represents propagated experimental systematic uncertainties.

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 Jun 25, 2014 *Colour (eps) *Colour (pdf) *Data |

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 Jun 25, 2014 *Colour (eps) *Colour (pdf) *Data |

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 Oct 19, 2012 *Colour (eps) *Colour (pdf) |

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.

10-064 DVCS deuterium |
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 Sep 17, 2010 *Colour (eps) *Colour (pdf) *Data INFO: The data values are contained in this entry. |

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].

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.

Simulated correlation between the values measured by the TGA or BRP detectors and their corresponding density-weighted average values in the storage cell. The three solid curves represent the three scenarios for the state of the cell surface: homogeneous cell (HC), homogeneous beam tube (HBT), and inhomogeneous beam tube (IBT). 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). The corresponding uncertainty grows rapidly with increasing recombination or depolarization Mar 28, 2005 *BW (eps) *BW (pdf) |

Possible beam-induced nuclear depolarizing resonances in the HERMES target. The frequency difference between pairs of hyperfine states whose transitions lead to nuclear depolarization are plotted as a function of the holding field. The frequency values are normalized to $\nu_{HERA}=10.42\,$MHz. The symbols representing the resonance conditions are clearly distinguishable for the $\pi$ transitions, while they overlap with each other in the case of $\sigma$ and $\pi\ket{3}\leftrightarrow\ket{6}$ transitions, which are separated by a difference in the intensity of the holding field $\Delta BT$ of only 0.37\,mT.

Multiplicities of pi+ as function of z obtained from 2000 unpolarised hydrogen data. 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 Sep 6, 2004 *Colour (eps) *Colour (pdf) INFO: The data has been corrected for RICH misidentifications, charge symmetric background and radiative and smearing effects.

The isoscalar-corrected ratio $RA / RD$ for several nuclei (A) with respect to deuterium as a function of $Q2$ for four different x bins. 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.
