Interpretation of the transverse-momentum distribution of particles in high-energy hadron collisions

Интерпретация распределения по поперечному импульсу для частиц в адронных соударениях при высоких энергиях

Summary

The characteristic Gaussian angular distribution of the two-body reactions produced by high-energy hadrons is correlated to the overall exponential distribution of the particles produced in the multibody processes. These properties, common to both the elastic and inelastic interactions, are then interpreted as the manifestation of the multiple scattering of subunits (possibly quarks) present in all hadrons.

Riassunto

Si mostra come la caratteristica distribuzione gaussiana dei processi in cui adroni di alta energia producono due corpi si possa collegare alla distribuzione esponenziale della sezione d'urto complessiva dei secondari prodotti nelle collisioni, di adroni, comprese quelle ad alta molteplicità. Queste proprietà sono comuni sia ai processi elastici che a quelli inelastici e si possono ricondurre allo scattering multiplo di sub-unità che dovrebbero essere presenti negli adroni; queste sub-unità probabilmente vanno identificate con i quark.

Резюме

Устанавливается соотношение между характеристическим гауссовым угловым распределением для двухчастичных реакций, производимых адронами высокой энергии, и общим экспоненциальным распределением частиц, рожденных в много-частичных процессах. Эти свойства, общие и для упругих и для неупругих взаимодействий, затем интерпретируются, как проявление многократного рассеяния некоторых элементарных единиц (возможно кварков), которые, как можно предположить, присутствуют во всех адронах.
