Weak duality and energy dependence of the slopes of elastic angular distributions

Слабая дуальность и знергетическая эависимость наклонов упругих угловых распределений

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

Summary

The problem of shrinking or antishrinking of the forward peak of elastic processes is studied within the framework of a weak-duality scheme. It is shown that, within such a scheme, the energy dependence of the slopes of the various elastic processes can be qualitatively understood. Thus, the result is in agreement with the experimental situation in the sense that K+p and pp shrink, K−p and\(\bar pp\) antishrink and π±p stay essentially constant.

Riassunto

Il problema della contrazione ed espansione del picco di diffrazione per processi elastici è studiato nell’ambito di uno schema di dualità debole. Si mostra che, entro tale schema, la dipendenza dall’energia delle pendenze dei vari processi elastici può essere spiegata qualitativamente. Pertanto, il risultato è in accordo con la situazione sperimentale nel senso che K+p e pp subiscono una contrazione, K−p e\(\bar pp\) si espandono e π±p restano essenzialmente constanti.

Реэюме

В рамках схемы слабой дуальности исследуется проблема сжатия и антисжатия пика в направлении вперед для упругих процессов. Покаэывается, что в рамках такой схемы знергетическая эависимость наклонов раэличных упругих процессов может быть общяснена качественно. Таким обраэом, полученный реэультат согласуется с зкспериментальной ситуацией в том смысле, что К+р и рр сжимаются, К−р и\(\bar pp\) р антисжимаются и π±р остаются, по сушеству, постоянными.

  16. In K+p, for instance, the partial-wave analysis (17) at 1.5 GeV/c was performed retainingS, P, D waves. The result showed that absorption is especially pronounced inP 13 andD 15. Four different kinds of solutions were then given to the determination of the various partial wavesS 11,P 11,P 13,D 13 andD 15 as the result of a best fit. Of these four groups of solutions, only the group IV of ref. (17) leads to positive polarization. As the polarization is indeed positive (18), one tentatively accepts the conclusion that a solution of type IV is preferred. The peculiarity of this solution is thatS 11,P 11 andD 13 always correspond to a repulsive interaction, whereasP 13 andD 15 are strongly absorbed and, in general, still correspond to repulsion or to a very small attraction. In the case of pp there exists a large number of partial-wave analyses which show (19) that a solution with strong repulsion is consistent with the experimental data.
