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 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...
متن کاملCharm and bottom production in two-photon collisions with OPAL
A preliminary update of the previous OPAL measurement of the inclusive production of D mesons in anti-tagged photon-photon collisions is presented together with the first preliminary OPAL measurement of bottom production in photon-photon collisions.
متن کاملHadron production in two-photon collisions at LEP-L3∗
The reaction ee → eeγγ → ee hadrons is analysed for quasi-real virtual photons using data collected by the L3 detector during the LEP high energy runs at √ s = 183 and 189 GeV. Preliminary results on the cross sections σ(ee → ee hadrons) and σ(γγ → hadrons) are given in the interval 5 GeV ≤ Wγγ ≤ 145 GeV. The centre-of-mass energy dependence of the two-photon cross section is well described by ...
