Review of Two-Photon Interactions
Presented are recent results of two-photon interactions. Topics inlcude photon structure functions, inclusive hadron production, differential cross sections derived from tagged γγ fusion events and results in exclusive hadron production, particularly the observations of the ηc. Two-photon interactions provide a unique opportunity to study a large variety of physics topics. In electron positron ...
متن کاملMultiple interactions in two-photon collisions.
We compute cross sections for events where two pairs of partons scatter off each other in the same γγ reaction, giving rise to at least 3 high–pT jets. Unlike in pp̄ collisions we find the signal to lie well above the background from higher order QCD processes. If the usual “eikonaliztion” assumption is correct, the signal should be readily observable at LEP2, and might already be detectable in ...
متن کاملMeson Resonance Production in Two-photon Processes
states are directly related to short-distance structure at their inside. It will give us an answer whether the meson is normal q q meson or an exotic one. Spin-parity, J P , of the mesons can be determined by investigating the angular distribution of the decay products in cooperation with limited degree of freedom in the initial state composed of two real photons. The study for the decay modes ...
متن کاملHeavy Flavour Production in Two-Photon Collisions
We review the production of charm and bottom quarks in two-photon collisions at ee colliders. The next-to-leading order QCD predictions for total cross sections and differential distributions are compared with recent experimental results.
متن کاملbaryon - antibaryon production in two - photon collisions
We study baryon pair production in two-photon collisions, γγ → BB̄, within perturbative quantum chromodynamics, treating baryons as quark-diquark systems. We extend previous work within the same approach by treating constituent-mass effects systematically by means of an expansion in the small parameter (mass/photon energy). Our approach enables us to give a consistent description of the cross se...
