First Measurement of Charged Current Cross Sections at HERA with Longitudinally Polarised Positrons

H1 Collaboration

Data taken with positrons of different longitudinal polarisation states in collision with unpolarised protons at HERA are used to measure the total cross sections of the charged cu…

Improved Measurement of the b-bbar Production Cross Section in 920 GeV Fixed-Target Proton-Nucleus Collisions

B Collaboration, I. Abt

A new measurement of the b-bbar production cross section in 920 GeV proton-nucleus collisions is presented by the HERA-B collaboration. The b-bbar production is tagged via inclusiv…

Search for the pentaquark candidate (1540) in the hyperon beam experiment WA89

M. I. Adamovich

We report on a high-statistics search for the \t1540 resonance in -nucleus collisions at 340 \gevc1 . No evidence for this resonance was found in our data sample which contain…

Search for Leptoquark Bosons in ep Collisions at HERA

H1 Collaboration

A search for scalar and vector leptoquarks coupling to first generation fermions is performed using the e^+p and e^-p scattering data collected by the H1 experiment between 1994 an…

Search for Pentaquarks with HERA-B

Joachim Spengler

A large data set of proton-nucleus collisions at sqrt(s) =41.6 GeV has been searched for Theta+ and Xi(1862) pentaquark candidates. In 2x10**8 inelastic events we find no evidence…

Complete results for five years of GNO solar neutrino observations

GNO COLLABORATION, M. Altmann, M. Balata +37

We report the complete GNO solar neutrino results for the measuring periods GNO III, GNO II, and GNO I. The result for GNO III (last 15 solar runs) is [54.3 + 9.9 - 9.3 (stat.)+- 2…

Search for Light Gravitinos in Events with Photons and Missing Transverse Momentum at HERA

H1 Collaboration

A search for gravitinos produced in ep collisions is performed using the H1 detector at HERA. The data were taken at a centre-of-mass energy of 319 GeV and correspond to an integra…
