Abstract

Dijet cross sections as functions of several jet observables are measured in photoproduction using the H1 detector at HERA. The data sample comprises e + p data with an integrated luminosity of 34.9 pb −1. Jets are selected using the inclusive k ⊥ algorithm with a minimum transverse energy of 25 GeV for the leading jet. The phase space covers longitudinal proton momentum fraction x p and photon longitudinal momentum fraction x γ in the ranges 0.05 < x p < 0.6 and 0.1 < x γ < 1. The predictions of next-to-leading order perturbative QCD, including recent photon and proton parton densities, are found to be compatible with the data in a wide kinematical range.

The European Physical Journal C - Particles and Fields, 2003

A measurement of inclusive jet cross-sections in deep-inelastic ep scattering at HERA is presented based on data with an integrated luminosity of 21.1 pb −1 . The measurement is performed for photon virtualities Q 2 between 5 and 100 GeV 2 , differentially in Q 2 , in the jet transverse energy E T , in E 2 T /Q 2 and in the pseudorapidity η lab . With the renormalization scale µ R = E T , perturbative QCD calculations in next-to-leading order (NLO) give a good description of the data in most of the phase space. Significant discrepancies are observed only for jets in the proton beam direction with E T below 20 GeV and Q 2 below 20 GeV 2 . This corresponds to the region in which NLO corrections are largest and further improvement of the calculations is thus of particular interest.

Measurement of dijet photoproduction at high transverse energies at HERA
Giuseppe Levi

The European Physical Journal C, 1999

The cross section for dijet photoproduction at high transverse energies is presented as a function of the transverse energies and the pseudorapidities of the jets. The measurement is performed using a sample of ep-interactions corresponding to an integrated luminosity of 6.3 pb −1 , recorded by the ZEUS detector. Jets are defined by applying a k T-clustering algorithm to the hadrons observed in the final state. The measured cross sections are compared to next-to-leading order QCD calculations. In a kinematic regime where theoretical uncertainties are expected to be small, the measured cross sections are higher than these calculations.

Inclusive D*±meson cross sections and D*±-jet correlations in photoproduction at HERA
Armine Hovhannisyan

The European Physical …, 2007

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 virtualities Q 2 < 0.01 GeV 2 and photon-proton centre-of-mass energies of 171 < W γ p < 256 GeV. The details of the heavy quark production process are further investigated in events with one or two jets in addition to the D * ± meson. Differential cross sections for D * +jet production are determined and the correlations between the D * ± meson and the jet(s) are studied. The results are compared with perturbative QCD predictions applying collinear-or k t-factorisation.

Dijet cross sections in photoproduction at HERA
Keith Furutani

The European Physical Journal C, 1998

Dijet cross sections are presented using photoproduction data obtained with the ZEUS detector during 1994. These measurements represent an extension of previous results, as the higher statistics allow cross sections to be measured at higher jet transverse energy (E jet T ). Jets are identified in the hadronic final state using three different algorithms, and the cross sections compared to complete next-to-leading order QCD calculations. Agreement with these calculations is seen for the pseudorapidity dependence of the direct photon events with E

Inclusive jet cross sections and dijet correlations in D ∗ ± photoproduction at HERA
maria victoria molina zambrana

Nuclear Physics B, 2005

Inclusive jet cross sections in photoproduction for events containing a D * meson have been measured with the ZEUS detector at HERA using an integrated luminosity of 78.6 pb −1 . The events were required to have a virtuality of the incoming photon, Q 2 , of less than 1 GeV 2 , and a photon-proton centre-ofmass energy in the range 130 < W γp < 280 GeV. The measurements are compared with next-to-leadingorder (NLO) QCD calculations. Good agreement is found with the NLO calculations over most of the measured kinematic region. Requiring a second jet in the event allowed a more detailed comparison with QCD calculations. The measured dijet cross sections are also compared to Monte Carlo (MC) models which incorporate leading-order matrix elements followed by parton showers and hadronisation. The NLO QCD predictions are in general agreement with the data although differences have been isolated to regions where contributions from higher orders are expected to be significant. The MC models give a better description than the NLO predictions of the shape of the measured cross sections.

Measurement of inclusive $D^{\ast\pm}$ and associated dijet cross sections in photoproduction at HERA
Bruce Mellado

The European Physical Journal C, 1999

Inclusive photoproduction of D * ± mesons has been measured for photon-proton centre-of-mass energies in the range 130 < W < 280 GeV and photon virtuality Q 2 < 1 GeV 2. The data sample used corresponds to an integrated luminosity of 37 pb −1. Total and differential cross sections as functions of the D * transverse momentum and pseudorapidity are presented in restricted kinematical regions and the data are compared with next-to-leading order (NLO) perturbative QCD calculations using the "massive charm" and "massless charm" schemes. The measured cross sections are generally above the NLO calculations, in particular in the forward (proton) direction. The large data sample also allows the study of dijet production associated with charm. A significant resolved as well as a direct photon component contribute to the cross section. Leading order QCD Monte Carlo calculations indicate that the resolved contribution arises from a significant charm component in the photon. A massive charm NLO parton level calculation yields lower cross sections compared to the measured results in a kinematic region where the resolved photon contribution is significant.

Inclusive jet cross sections in D * ± photoproduction at HERA has been measured in photon-proton center of mass energy from 130 GeV to 280 GeV. The analysis is based on the integrated luminosity of 78.6 pb −1 taken by the ZEUS detector. D * ± was measured in the kinematic region p T (D * ) > 3 GeV/c and |η(D * )| < 1.5. Jet cross sections have been measured with the aim to have better correspondence between the observable (jet) and the outgoing parton, and also to extend the measurement towards the proton direction. Differential cross sections as a function of the transverse energy (E jet T ) and the pseudorapidity (η jet ) of jets were measured in the range E jet T > 6 GeV and −1.5 < η jet < 2.4. The η jet cross sections are reasonably described by the next-to-leading order (NLO) QCD calculation corrected for hadronization effect. The measured cross sections are larger than the NLO QCD predictions, but agrees within the theoretical uncertainty except for the highest measured E jet T where an excess of 3σ is observed. At high E jet T , by studying the ratio of the transverse momentum of the D

    Search for squarks in R -parity violating supersymmetry in ep collisions at HERA
    Andrei Dobre

    European Physical Journal C, 2011

    A search for squarks in R-parity violating supersymmetry is performed in e ±p collisions at HERA using the H1 detector. The full data sample taken at a centre-of-mass energy $\sqrt{s}=319$ GeV is used for the analysis, corresponding to an integrated luminosity of 255 pb−1 of e +p and 183 pb−1 of e −p collision data. The resonant production of squarks via a Yukawa coupling λ′ is considered, taking into account direct and indirect R-parity violating decay modes. Final states with jets and leptons are investigated. No evidence for squark production is found and mass dependent limits on λ′ are obtained in the framework of the Minimal Supersymmetric Standard Model and in the Minimal Supergravity Model. In the considered part of the parameter space, for a Yukawa coupling of electromagnetic strength λ′=0.3, squarks of all flavours are excluded up to masses of 275 GeV at 95% confidence level, with down-type squarks further excluded up to masses of 290 GeV.
