Vector Meson Pair Production in Two - Photon Collisions near Threshold
The cross sections for several γγ → V V processes exhibit strong enhancements near threshold, where V denotes a vector meson. The pattern of these enhancements is not well understood; for example, γγ → ρρ shows an appreciable peak, while γγ → ρρ does not. Some possible mechanisms for this behavior are discussed. Tests are proposed involving production of systems containing heavier quarks, e.g.,...
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 کاملD∗ Production in Two-photon Collisions
We calculate total and differential production rates of D∗ mesons in two-photon collisions at LEP2. We include full next-to-leading order QCD corrections, and perform an extensive study of the sensitivity of our predictions to variations of the renormalization scale, charm mass, photonic parton distribution set and fragmentation function. The results are compared with recent data from LEP2. CER...
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...
