Notes on ultra-high-energy interaction processes

Некоторые эамечания о процессах вэаимодействия при сверхвысоких знергиях

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

An attempt is made to develop a picture of ultra-high-energy interaction processes which is consistent with the known data of cosmic rays. At low energies these data are drawn from the results of emulsions, emulsion chambers and other installations (such as the Echo Lake facility). At high energies these data are inferred from the response of the giant arrays designed to measure air showers initiated by primaries with incident energy (E 0) as high as (1010÷1020) eV. A possible link between multiplicity increase and observed transverse momenta is discussed in terms of four-momentum damping. In addition, resonance formation and expected average elasticity are considered.

Riassunto

Si fa un tentativo di sviluppare un quadro dei processi di interazione di altissima energia che sia coerente con i dati conosciuti sui raggi cosmici. A basse energie questi dati sono ricavati da emulsioni, camere ad emulsione ed altre istallazioni (come l’impianto di Echo Lake). Ad alte energie questi dati si deducono dalle risposte dei sistemi giganteschi progettati per misurare sciami dell’aria iniziati da primari con energia incidente (E 0) di almeno (1019÷1020) eV. Si discute un possibile legame fra l’aumento delle molteplicità e gli impulsi trasversali osservati in termini dello smorzamento del quadrimpulso Inoltre si studiano la formazione di risonanze e l’energia media prevista.

Реэюме

Предпринимается попытка раэвить картину процессов вэаимодействия при сверхвысоких знергиях, которая не противоречила бы иэвестным данным для космических лучей. При ниэких знергиях зти данные иэвлекаются иэ реэультатов, полученных в змульсиях, змульсионных камерах и других установках. При высоких знергиях зти данные получаются иэ отклика гигантских цепочек, сконструированных для иэмерения воэдущных ливней, рожденных первичными частицами с начальной знергией (E 0) порядка (1019÷1020) зВ. В терминах эатухания четырех-импульса обсуждается воэможная свяэь между увеличением множественности и наблюденными поперечными импульсами. Кроме того, рассматриваются обраэование реэонанса и ожидаемая средняя упругость.
