A detailed analysis is presented of the diffractive deep-inelastic scattering process ep → eXY , where Y is a proton or a low mass proton excitation carrying a fraction 1−x I P > 0.95 of the incident proton longitudinal momentum and the squared four-momentum transfer at the proton vertex satisfies |t| < 1 GeV 2. Using data taken by the H1 experiment, the(More)
Nanocomposites consisting of one-dimensional CuI crystals inside single-walled carbon nanotubes were obtained using the capillary technique. high-resolution transmission electron microscopy investigations of the atomic structure of the encapsulated 1D CuI crystals revealed two types of 1D CuI crystals with growth direction <001> and <110> relative to the(More)
The cross section for the diffractive deep-inelastic scattering process ep → eXp is measured , with the leading final state proton detected in the H1 Forward Proton Spectrometer. The data analysed cover the range x IP < 0.1 in fractional proton longitudinal momentum loss, 0.08 < |t| < 0.5 GeV −2 in squared four-momentum transfer at the proton vertex, 2 < Q(More)
Measurements are presented of differential dijet cross sections in diffractive photoproduc-tion (É ¾ ¼¼½ GeV ¾) and deep-inelastic scattering processes (DIS, É ¾ ¼ GeV ¾). The event topology is given by Ô , in which the system , containing at least two jets, is separated from a leading low-mass proton remnant system by a large rapidity gap. The dijet cross(More)
Differential photoproduction cross sections are measured for events containing D * ± mesons. The data were taken with the H1 detector at the ep collider HERA and correspond to an integrated luminosity of 51.1 pb −1. The kinematic region covers small photon vir-tualities Q 2 < 0.01 GeV 2 and photon-proton centre-of-mass energies of 171 < W γ p < 256 GeV. The(More)
A measurement of charm and beauty dijet photoproduction cross sections at the ep collider HERA is presented. Events are selected with two or more jets of transverse momentum p jet 1(2) t > 11(8) GeV in the central range of pseudo-rapidity −0.9 < η jet 1(2) < 1.3. The fractions of events containing charm and beauty quarks are determined using a method based(More)
The production of leading neutrons, where the neutron carries a large fraction x L of the incoming proton's longitudinal momentum, is studied in deep-inelastic positron-proton scattering at HERA. The data were taken with the H1 detector in the years 2006 and 2007 and correspond to an integrated luminosity of 122 pb −1. The semi-inclusive cross section is(More)
A search for second and third generation scalar and vector leptoquarks produced in ep collisions via the lepton flavour violating processes ep → µX and ep → τ X is performed by the H1 experiment at HERA. The full data sample taken at a centre-of-mass energy √ s = 319 GeV is used for the analysis, corresponding to an integrated luminosity of 245 pb −1 of e +(More)
Events with high energy isolated electrons, muons or tau leptons and missing transverse momentum are studied using the full e ± p data sample collected by the H1 experiment at HERA, corresponding to an integrated luminosity of 474 pb −1. Within the Standard Model, events with isolated leptons and missing transverse momentum mainly originate from the(More)
Measurements of cross sections for beauty and charm events with dijets and a muon in the photoproduction regime at HERA are presented. The data were collected with the H1 detector and correspond to an integrated luminosity of 179 pb −1. Events with dijets of transverse momentum P jet1 T > 7 GeV and P jet2 T > 6 GeV in the pseudorapidity range −1.5 < η jet <(More)
