The inclusive e+p single and double differential cross sections for neutral and charged current processes are measured with the H1 detector at HERA. The data were taken in 1999 and 2000 at a centre-of-mass energy of √ s = 319GeV and correspond to an integrated luminosity of 65.2 pb−1. The cross sections are measured in the range of four-momentum transfer(More)
The inclusive single and double differential cross-sections for neutral and charged current processes with four-momentum transfer squared Q2 between 150 and 30 000 GeV2 and with Bjorken x between 0:0032 and 0:65 are measured in e+p collisions. The data were taken with the H1 detector at HERA between 1994 and 1997, and they correspond to an integrated(More)
OBJECTIVE Although immunoglobulin (Ig)E-mediated allergies are readily identifiable, non-IgE-mediated allergies present more diagnostic difficulty. We performed a formal retrospective analysis to determine whether there is a recognizable clinical pattern in children. METHODS We studied 121 children (mean age, 17.3 months) with multiple food allergies who(More)
We describe the design of a digital calorimeter trigger processor system which could form a major part of the ATLAS level-1 trigger system. Utilising novel techniques, but with today’s technologies, the system can be contained within six electronics crates and will provide the central trigger logic with signals from events with high-pT electrons, photons,(More)
A study is presented of the process γp → XY , where there is a large rapidity gap between the systems X and Y . Measurements are made of the differential cross section as a function of the invariant massM X of the system produced at the photon vertex. Results are presented at centre of mass energies of 〈W 〉 = 187 GeV and 〈W 〉 = 231 GeV, both where the(More)
A dietitian discusses the theory that peptides with opioid activity may cause or trigger autism. The use of an exclusion diet to treat autism is explained, weighing the potential benefits against some of the practical difficulties of keeping to a strict exclusion diet. The use of nutritional supplements is described. An abnormal gut flora has also been(More)
Deep–inelastic scattering events with a leading baryon have been detected by the H1 experiment at HERA using a forward proton spectrometer and a forward neutron calorimeter. Semi–inclusive cross sections have been measured in the kinematic region 2 Q2 50 GeV2, 6 10 5 x 6 10 3 and baryon pT 200 MeV, for events with a final state proton with energy 580 E 0(More)
Deep-inelastic positron-proton interactions at low values of Bjorken-x down to x ≈ 4 · 10 which give rise to high transverse momentum π-mesons are studied with the H1 experiment at HERA. The inclusive cross section for π-mesons produced at small angles with respect to the proton remnant (the forward region) is presented as a function of the transverse(More)
The elastic electroproduction of mesons is studied at HERA with the H1 detector for a photon virtuality in the range 1 < Q2 < 60 GeV2 and for a hadronic centre of mass energy in the range 30 < W < 140 GeV. The shape of the ( ) mass distribution in the resonance region is measured as a function of Q2. The full set of spin density matrix elements is(More)
Transverse momentum spectra of charged particles produced in deep inelastic scattering are measured as a function of the kinematic variables x and Q using the H1 detector at the ep collider HERA. The data are compared to different parton emission models, either with or without ordering of the emissions in transverse momentum. The data provide evidence for a(More)
