04-005 EXOTICS pentaquark |
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 Feb 7, 2004 *Colour (eps) *Colour (pdf) |

Spectra of invariant mass $M_{pK^-}$ (top) and M_{pK^+} (bottom). A clear peak is seen for the \Lambda(1520) in the M_{pK^-} invariant mass distribution.

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 Feb 7, 2004 *Colour (eps) *Colour (pdf) |

The average strange quark helicity density $x\cdot[\Delta s(x)+\Delta\bar{s}(x)]/2$ from the isoscalar extraction method (full points). For comparison the open symbols denote the results from a five parameter fit (see text), which are offset horizontally for presentation. The band in the bottom part gives the total systematic uncertainty on the results from the isoscalar extraction.

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.

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 broad band is the \pm 1 sigma zone of allowed values predicted by the neural network (NNPDF2.3) reference set [14].

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).

DVCS overview plot showing all azimuthal asymmetry amplitudes in the entire HERMES kinematic range ("overall"/"integrated") from data taken in the years 1996-2007. This includes data on the unpolarized hydrogen and deuterium targets, the longitudinally polarized hydrogen and deuterium targets and the transversely polarized hydrogen target. Shown are the leading amplitudes of the beam charge, the beam helicity, the target spin and the double spin asymmetries, which are all sensitive to different GPDs (real or imaginary part of corresponding Compton form factors). The inner error bars give the statistical uncertainties, the outer error bars the quadratic sum of statistical and systematic uncertainties Jun 20, 2012 *Colour (eps) *Colour (pdf) INFO: The data shown in this plot are published (final: DC68, DC39, DC80, DC81, DC90, DC91).

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.

Beam charge asymmetry amplitudes in Deeply Virtual Compton Scattering (DVCS) from a hydrogen target. Shown are the cos0\phi, cos\phi, cos2\phi, and cos3\phi amplitudes in bins of -t for 3 different bins in xB and resulting different average Q2 (2-dimensional representation, otherwise as 09-071). The statistical uncertainties are indicated by the error bars, the systematic uncertainies by the error bands. All 1996-2005 hydrogen data Nov 2, 2009 *Colour (eps) *Colour (pdf) *Data INFO: The 2 dimensional data values are contained in the file attached to this entry. |

Beam charge asymmetry amplitudes in Deeply Virtual Compton Scattering (DVCS) from a hydrogen target. Shown are the cos0\phi, cos\phi, cos2\phi, and cos3\phi amplitudes in bins of -t, xB, or Q2 (1-dimensional representation). Also shown is the integrated value presenting the data in a single bin ('overall'). All 1996-2005 hydrogen data. The bottom row gives for each bin the fraction of the 'associated' process where the proton is excited to a resonant state. The statistical uncertainties are indicated by the error bars, the systematic uncertainies by the error bands. Also shown are model calculations using the 'VGG' model, or the Dual 'GT' model Nov 2, 2009 *Colour (eps) *Colour (pdf) *Data INFO: The 1 dimensional data values are contained in the file attached to this entry. |
