Azimuthal angles in diffractive

AZIMUTHAL ANGLES IN DIFFRACTIVE ep COLLISIONS

We investigate azimuthal correlations in deep inelastic diffractive scattering, e+ p → e+ p̃+X. The dependence of the ep cross section on the angle between the lepton plane and some direction in the hadronic final state has a simple relation with cross sections and interference terms of the subreaction γ∗+p → X+ p̃. Its measurement can be used to constrain the cross section for longitudinally pol...

Azimuthal Dependence in Diffractive Processes

Azimuthal distributions in high-energy processes give information about the helicity structure of diffractive reactions. I discuss predictions of several dynamical mechanisms in this context, both for electron-proton and for hadron-hadron collisions. 1 Azimuthal distributions in ep diffraction In this talk I give several examples of what azimuthal distributions can tell us about diffractive int...

Azimuthal Distribution of Quark-Antiquark Jets in DIS Diffractive Dissociation

We investigate the azimuthal distribution of quark-antiquark jets in DIS diffractive dissociation with large transverse momentum. In this kinematical region the matrix element is expressed in terms of the gluon structure function. For the transverse part of the cross section we find a cos(2φ)-distribution with the maximum at φ = ±π/2, i.e. the jets prefer a direction perpendicular to the electr...

A seven-dimensional quantum dynamics study of the dissociative chemisorption of H2O on Cu(111): effects of azimuthal angles and azimuthal angle-averaging

We report the first seven-dimensional quantum dynamics study for the dissociative chemisorption of H2O on Cu(111) using the time-dependent wave-packet approach, based on an accurate nine-dimensional potential energy surface (PES), which is newly developed by neural network fitting to 80 000 density functional theory points. This seven-dimensional quantum model allows the examination of the infl...
