Model discrimination in pseudoscalar-meson photoproduction

Article history: Received 8 March 2016 Received in revised form 22 April 2016 Accepted 21 May 2016 Available online 26 May 2016 Editor: V. Metag To learn about a physical system of interest, experimental results must be able to discriminate among models. We introduce a geometrical measure to quantify the distance between models for pseudoscalarmeson photoproduction in amplitude space. Experimen...

Light Vector Meson Photoproduction at High |t|

We have studied in perturbative QCD all independent helicity amplitudes describing the photoproduction of light vector mesons at large t. We found a new hard production mechanism which is related to the possibility for a real photon to fluctuate into a massless q ¯ q pair in a chiral-odd spin configuration. Each helicity amplitude is given as a sum of chiral-even contribution (when the heliciti...

Nuclear Diffractive Structure Functions at High Energies

A future high-energy electron-ion collider would explore the non-linear weakly-coupled regime of QCD, and test the Color Glass Condensate (CGC) approach to high-energy scattering. Hard diffraction in deep inelastic scattering off nuclei will provide many fundamental measurements. In this work, the nuclear diffractive structure function F 2,A is predicted in the CGC framework, and the features o...

Ambiguities in the partial-wave analysis of pseudoscalar-meson photoproduction.

Ambiguities in the partial-wave analysis of pseudoscalar-meson photoproduction Abstract Ambiguities in pseudoscalar-meson photoproduction, arising from incomplete experimental data, have analogs in pion-nucleon scattering. Amplitude ambiguities have important implications for the problems of amplitude extraction and resonance identification in partial-wave analysis. The effect of these ambiguit...

Completeness Rules for Spin Observables in Pseudoscalar Meson Photoproduction

The number and type of measurements needed to ascertain the amplitudes for pseudoscalar meson photoproduction are analyzed in this paper. It is found that 8 carefully selected measurements can determine the four transversity amplitudes without discrete ambiguities. That number of measurements is one less than previously believed. We approach this problem in two distinct ways: (1) solving for th...
