Two hadron production in e+e- annihilation to next-to-leading order accuracy

Mostrar todas las versiones(3)

We discuss the production of two hadrons in e+e- annihilation within the framework of perturbative QCD. The cross section for this process is calculated to next-to-leading order accuracy with a selection of variables that allows the consideration of events where the two hadrons are detected in the s...
