Summary
A constituent multichain model in the (1+1) dimension is presented which gives exclusive and inclusive distribution functions of multimeson final states in hadronic soft collisions, in e+e− annihilations and in deep inelastic electroproductions. Scaling behaviour of inclusive quantities in hadronic and deep inelastic phenomena is unifiedly understood as due to a balance between tension and fragility of the constituent chain, on the basis of a two-phase picture of constituent urbaryons. The extension of the model to full dimensions and other ingredients towards the real world are discussed, and remarks on related approaches are given.
Riassunto
Si presenta un modello costituente a molte catene (1+1)-dimensionale che dà funzioni di distribuzione esclusive ed inclusive di stati finali multimesonici nelle collisioni adroniche molli, nell’annichilazioni e+e− e nell’elettroproduzione anelastica profonda. Si comprende in modo unificato il comportamento di variazione di scala delle quantità inclusive nei fenomeni adronici e anelastici profondi come dovuti ad un equilibrio fra la tensione e la fragilità della catena costituente sulla base di un quadro a due fasi di urbarioni costituenti. Si discutono l’estensione del modello a tutte le dimensioni ed altri ingredienti verso il mondo reale, e si fanno osservazioni sugli approcci relativi.
Резюме
Предлагается составная много-цепная модель в (1+1)-измерении, которая дает эксклюзивные и инклюзивные функции распределения для многомезонных конечных состояний при мягких адронных соударениях, e+e− аннигиляциях и глубоко-неупрутих электророждениях. Поведение скейлинга для инклюзивных величин в адронных и глубоко-неупругих явлениях обБясняется с помощью баланса между напряжением и хрупкостью составляющих цепи на основе двухфазной картины составляющих «урбарионов». Рассматривается расширение модели на полное число измерений и другие ингредиенты, относящиеся к реальному миру. Обсуждаются использованные приближения.
