D∗ 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 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 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 کاملResonance Formation in Two-photon Collisions
Two-photon collisions at electron positron storage rings are a good laboratory to investigate the properties of meson resonances and play a crucial role in glueball searches. A resonant state R can be formed by the collision of two photons via the reaction e+e− → e+e−R (fig. 1). The outgoing electron and positron are usually scattered at very small angles and are not detected (no-tag mode). In ...
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...
