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)
New control system aspects are introduced for the design of slow control systems for physical experiments. Mainly, they are based on a comprehensive usage of XML technologies. A second paradigm for future control systems is the consequent usage of the Model-View-Controller (MVC) pattern. Main aspect of all (hardware and software) system components is the(More)
The elastic electroproduction of ρ mesons is studied at HERA with the H1 detector for a photon virtuality in the range 1 < Q < 60 GeV and for a hadronic centre of mass energy in the range 30 < W < 140 GeV. The shape of the (ππ) mass distribution in the ρ resonance region is measured as a function of Q. The full set of ρ spin density matrix elements is(More)
The electroproduction of J/ψ and ψ(2S) mesons is studied in elastic, quasi-elastic and inclusive reactions for four momentum transfers 2 < Q < 80 GeV and photon-proton centre of mass energies 25 < W < 180 GeV. The data were taken with the H1 detector at the electron proton collider HERA in the years 1995 to 1997. The total virtual photon-proton cross(More)
A precise measurement of the inclusive deep-inelastic ep scattering cross section is reported in the kinematic range 1.5 ≤ Q ≤ 150GeV and 3 · 10 ≤ x ≤ 0.2. The data were recorded with the H1 detector at HERA in 1996 and 1997, and correspond to an integrated luminosity of 20 pb. The double differential cross section, from which the proton structure function(More)
Familial Mediterranean Fever (FMF) is an inherited, recessively transmitted inflammatory condition usually occurred in populations from Mediterranean descent (Armenian, Arab, Jewish, Greek, Turkish and Italian populations). Identification of MEFV gene mutations has been of tremendous help for early diagnosis of most cases. The frequency of FMF is different.(More)
A search for squarks in R-parity violating supersymmetry is performed in ep collisions at HERA at a centre of mass energy of 300 GeV, using H1 data corresponding to an integrated luminosity of 37 pb. The direct production of single squarks of any generation in positron-quark fusion via a Yukawa coupling λ is considered, taking into account R-parity(More)
A search for events with an imbalance in transverse momentum and with isolated high energy leptons has been carried out at the positron-proton collider HERA. One event with an e and five events with a are found together with evidence for undetected particles carrying transverse momentum. Within the Standard Model the dominant origin of events with this kind(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)
