Exclusive production of pion and kaon meson pairs in two photon collisions at LEP
Creators
Description
Exclusive production of π and K meson pairs in two photon collisions is measured with ALEPH data collected between 1992 and 2000. Cross sections are presented as a function of cos σ* and invariant mass, for t vertical bar cosσ* vertical bar < 0.6 and invariant masses between 2.0 and 6.0 GeV/c2) for pions (kaons). The shape of the distributions are found to be well described by QCD predictions but the data have a significantly higher normalisation
