Mass values and experimental FWHM widths observed in various experiments for the $\Theta^+$ state. The inner error bars represent the statistical uncertainties, and the outer error bars represent the quadratic sum of the statistical and systematic uncertainties. (Some uncertainties for the widths are not available from the other experiments.) The hatched area corresponds to the weighted average of all data \pm1 standard deviation

Distribution in invariant mass of the $p \pi^+\pi^-$ system. The experimental data are represented by the filled circles with statistical error bars, while the fitted smooth curves result in the indicated position and \sigma width of the peak of interest. In panel a), the PYTHIA-6 Monte Carlo simulation is represented by the gray shaded histogram, the mixed-event model normalised to the PYTHIA-6 simulation is represented by the fine-binned histogram, and the fitted curve is described in the text. In panel b), a fit to the data of a Gaussian plus a third-order polynomial is shown

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 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

INFO: supportive plot for the partial cross section for P>6GeV of the anti-Lambda(1520) (with Pz > 6.0 GeV) = 9.8 +/- 2.6 (stat) +/- 0.9 (syst) nb and the ratio anti-Lambda(1520)/Lambda(1520)= 0.15 +/- 0.05 (stat) +/- 0.02 (syst). Particle and anti-particle are assumed to be produced unpolarised. The systematic uncertainty in the cross section ratio is obtained from the variation in the signal counts when varying the fits for the mass peaks within the total uncertainty of the determined mass.

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 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 open points and the dashed curve show the data and fit published previously in Ref. [7]

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

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

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.

Charge-difference double-spin asymmetry amplitudes describing the dependence of the interference term on transverse target polarization in combination with beam helicity and beam charge extracted from hydrogen target data. The error bars (bands at the bottom of the panels) represent the statistical (systematic) uncertainties. There is an additional overall 8.6 % scale uncertainty arising from the uncertainties in the measurements of the beam and target polarizations. The curves show the results of theoretical calculations using the VGG double-distribution model with a Regge ansatz for modeling the t dependence of GPDs. The widths of the curves represent the effect of varying the total angular momentum Ju of u-quarks between 0.2 and 0.6, with Jd=0. The bottom row shows the fractional contribution of associated BH production as obtained from a MC simulation

proton
Momenta and azimuthal angles for exclusive real-photon electroproduction in the target rest frame. The quantity phi denotes the angle between the lepton scattering plane containing the three-momenta k and k' of the incoming and outgoing lepton and the photon production plane correspondingly defined by the vector q=k-k' and the momentum q' of the real photon. The symbol phiS denotes the angle between the lepton scattering plane and S_\perp , the component of the target polarization vector that is orthogonal to q . These definitions are consistent with the Trento conventions

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
