Combined measurement and QCD analysis of the inclusive e(+/-)p scattering cross sections at HERA
- 2010

Ingår i: Journal of High Energy Physics. - 1029-8479. ; :1

Tidskriftsartikel (refereegranskat)abstract
- A combination is presented of the inclusive deep inelastic cross sections measured by the H1 and ZEUS Collaborations in neutral and charged current unpolarised e(+/-)p scattering at HERA during the period 1994-2000. The data span six orders of magnitude in negative four-momentum-transfer squared, Q(2), and in Bjorken x. The combination method used takes the correlations of systematic uncertainties into account, resulting in an improved accuracy. The combined data are the sole input in a NLO QCD analysis which determines a new set of parton distributions, HERAPDF1.0, with small experimental uncertainties. This set includes an estimate of the model and parametrisation uncertainties of the fit result.

Events with an isolated lepton and missing transverse momentum and measurement of W production at HERA
- 2010
-
Ingår i: Journal of High Energy Physics. - 1029-8479. ; 2010:3, s. 1-19

Tidskriftsartikel (refereegranskat)abstract
- A search for events containing an isolated electron or muon and missing trans verse momentum produced in e(+/-)p collisions is performed with the H1 and ZEUS detectors at HERA. The data were taken in the period 1994-2007 and correspond to an integrated luminosity of 0.98 fb(-1). The observed event yields are in good overall agreement with the Standard Model prediction, which is dominated by single W production. In the e(+)p data, at large hadronic transverse momentum P-T(X) > 25GeV, a total of 23 events are observed compared to a prediction of 14.0 +/- 1.9. The total single W boson production cross section is measured as 1.06 +/- 0.16 (stat.) +/- 0.07 (sys.) pb, in agreement with an Standard Model (SM) expectation of 1.26 +/- 0.19 pb.

Multi-leptons with high transverse momentum at HERA

Ingår i: Journal of High Energy Physics. - : Springer Science and Business Media LLC. - 1029-8479. ; :10
-
Tidskriftsartikel (refereegranskat)abstract
- Events with at least two high transverse momentum leptons (electrons or muons) are studied using the H1 and ZEUS detectors at HERA with an integrated luminosity of 0.94 fb(-1). The observed numbers of events are in general agreement with the Standard Model predictions. Seven di- and tri-lepton events are observed in e(+)p collision data with a scalar sum of the lepton transverse momenta above 100 GeV while 1.94 +/- 0.17 events are expected. Such events are not observed in e(-)p collisions for which 1.19 +/- 0.12 are predicted. Total visible and differential di-electron and di-muon photoproduction cross sections are extracted in a restricted phase space dominated by photon-photon collisions.

Dip and hat pattern: a phonological contrast of German?
- 2008

- Is the high plateau in a ‘hat pattern’ a phonetic artefact, or does it reflect a phonological feature? Can it contrast with a low plateau, i.e., a ‘dip pattern’? The presented perception experiment supports the phonological point of view, since it shows that the dip/hat contrast can disambiguate German oder-constructions, which are interpretable as ‘alternative’ or ‘yes/no-questions’. This specific function may be derived from a more general substance–function relation: While a hat pattern has a ‘bracketing function’, a dip signals detachment.

Focal F0 peak shape and sentence mode in Swedish

Konferensbidrag (refereegranskat)abstract
- Shape characteristics of rising-falling accentual F0 peaks of Stockholm Swedish Accent I words in narrow focus are studied in a corpus of 287 read sentences. The corpus includes statements and three types of polar questions. Results reveal a clear effect of sentence mode on the shape of the accentual rises: Statements are predominantly characterized by convex rises, questions by concave rises.

Alignment of Medial and Late Peaks in German Spontaneous Speech
- 2006

Konferensbidrag (refereegranskat)abstract
- Starting from a corpus of German spontaneous speech, the phonetic realisations of the two KIM categories medial and late peak were investigated in prenuclear position. The results show that, for both categories, the onset of the rising F0 movement (L) is comparably aligned around the accented-syllable onset, whereas the F0 maximum (H) is independently aligned and predominantly located before the accented-syllable offset or after the onset of the following unaccented syllable, respectively. The data further suggest that also from the AM point of view the two prenuclear rises are different at the phonological level. Finally, the possibility is pointed out that the alignment patterns found for prenuclear rises in other studies are to some extent due to a combination of categories like the medial and late peak.
