2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/49667The calculation of the tree-level QCD processes e+e- -> qqgggg, qqqqgg and qqqqqq has recently been accomplished. We highlight here the relevance of such reactions for some of the physics at future electron-positron linear accelerators.6 pages, latex, 4 figures (talk given at the 2nd ECFA/DESY Study on Physics and Detectors for a Linear Electron-Positron Collider, Lund, Sweden, 28-30 June 1998): LC-note number added, complete paper also available at http://www.desy.de/~lcnotes/notes.htmlHigh Energy Physics - Phenomenologytext
