Prompt photon production at colliders

Physical Review D, 1990
We discuss the uncertainties affecting the theoretical predictions for prompt-photon production at collider energies. The importance of studying the rapidity distribution at small values of the transverse momentum is emphasized as a means to probe the gluon distribution at low {ital x}.

Hadron production in photon-photon collisions

Physical Review D, 1976
We analyze deep-inelastic photon-photon collisions via the two-photon mechanism in electron-positron (-electron) colliding beams in a form especially suitable for experimental analysis. It is shown that by a helicity analysis similar to that used in electroproduction experiments, we can separate five of the eight structure functions describing the ...

Pair Production in Photon-Photon Collisions

Physical Review, 1967
General formulas for the absorption probability from the process $\ensuremath{\gamma}+{\ensuremath{\gamma}}^{\ensuremath{'}}\ensuremath{\rightarrow}{e}^{+}+{e}^{\ensuremath{-}}$ are given for high-energy photons traversing isotropic photon gases having various spectra.

Pion pair production in photon-photon interactions

Zeitschrift für Physik C Particles and Fields, 1984
The processγγπ+π− has been measured with complete particle identification. Cross-sections are presented from near threshold up to the region of thef(1270). In the mass range 0.5–0.7 GeV, crosssections are lower than the Born term predictions and show no evidence for an e(600). The two-photon width of thef(1270) is found to be in agreement with previous

ρ0ρ0 production in photon-photon interactions

AIP Conference Proceedings, 1989
Existing experimental data on γγ→ρ0ρ0 are reviewed. It is showed that the published results for spin‐parity composition of the cross section are not consistent with each other. A Monte‐Carlo study is performed to trace the origin of the disagreement.

Tensor meson production in photon-photon collisions

Journal of Physics G: Nuclear Physics, 1979
Recent work on the electromagnetic properties of tensor mesons is extended to their production in e+e- collisions via the two-photon process. It is shown how the model proposed can be tested experimentally.
