Radiation from cygnus X-3 and the related muon puzzle—An explanation

Summary

Recent measurements by various experimental groups have established very firmly that the photoproduced air showers at cosmic-ray energies are not at all muon-poor, as they were believed to be from all standard theoretical calculations. We have explored here one possibility of its supposedly nonstandard and nonconventional origin and have found, to our surprise, that our theoretical results for various measured parameters are in astonishing agreement with experimental abservations. In essence, this amounts to the removal of all so-called anomalies by induction of a new physical picture about the structure of hadrons and some new insights. This work assumes a special importance in view of the fact that Cygnus muons are believed to be the only challenge to the standard model of quarks and leptons as commented very recently by Gaisser and Halzen.

Riassunto

Misure recenti di vari gruppi sperimentali hanno stabilito che gli sciami fotoprodotti ad energie dei raggi cosmici non sono del tutto poveri di muoni come si credeva in base a tutti i calcoli teorici standard. Si è esplorata qui una possibilità della loro supposta origine non standard e non convenzionale e si è trovato, sorprendentemente, che i risultati teorici per vari parametri misurati sono in accordo eccellente con le osservazioni sperimentali. Essenzialmente, ciò corrisponde all'eliminazione di tutte le cosiddette anomalie introducendo una nuova rappresentazione fisica della struttura degli adroni e di nuove prospettive. Questo lavoro assume una particolare importanza alla luce del fatto che i muoni di Cygnus sono ritenuti l'unico dato che mette in discussione il modello standard dei quark e dei leptoni come è stato osservato recentemente da Gaisser e Halzen.

Резюме

Недавние измерения, проведенные различными экспериментальными группами, установили, что атмосферные ливни, образованные фотонами с энергиями космических лучей, оказываются совсем не с малыми содержанием мюонов, как считалось из всех стандартных теоретических вычислений. Мы исследуем одну возможность нестандартного и не общепринятого происхождения. Обнаружено, что наши теоретические результаты для различных измеренных параметров удивительно хорошо согласуются с экспериментальными данными. По-существу, этот подход исключает все так называемые аномалии посредством введения новой физической картины для структуры адронов и некоторых новых представлений. В этой работе особое внимание уделяется тому факту, что мюоны из Лебедя представляют единственное возражение стандартной модели кварков и лептонов, как отмечалось недавно Гейзером и Хальзеном.
