Abstract

An analysis of experimental facts in low and highenergy hadron interactions and theoretical results in gauge field theory leads to the conclusion that theSU6 totally spontaneously broken temporary free gauge field model is a natural candidate for a description of strong hadron interactions The model is based on the observed massive vector mesons and fermions It is shown that the Higgs sector can be chosen in such a manner that—even after totalSU6 symmetry breaking—there survives a global symmetrySU2×U 1 s ×U 1 c ×U 1 b ×U 1 t which coincides with the observed isospin strangeness charm beauty and top symmetry The renormalization group analysis indicates that the model is temporarily free It is shown that all vector mesons reggeize and their parent and daughter Regge trajectories are calculated in the leadinglogarithm approximation It is shown also that all fundamental fermions which can be taken either in vector or adjoint representation also reggeize Due to temporary freedom the model possesses the scaling properties and enables a perturbative analysis of highenergy of processes Since the model is based on observed hadrons the analysis of exclusive processes is considerably facilitated It is shown in particular that the model predicts a new form of baryonbaryon and baryonantibaryon highenergy total crosssection it is noteworthy that the obtained cross sections are decreasing for moderately high energy and increasing for higher energies in a remarkable agreement with experimental data in the energy interval 10 GeVundersetraise03emhboxsmashscriptscriptstylethicksim sqrt s undersetraise03emhboxsmashscriptscriptstylethicksim 30 000 GeVАнализ экспериментальных данных по взаимодействиям адронов с низкими и высокими энергиями и теоретические редультаты в калибровочной теории поля приводят к выводу чтоSU6 спонтанно нарушенная модель временно свободного калибровочного поля представляет естественный кандидат для описания сильных взаимодействий адронов Эта модель основана на наблюдаемых массивных векторных мезонах и фермионах Показывается что сектор Хигтса может быть выбран таким образом что после полного нарушенияSU6 симметрии существует глобальная симметрияSU2×U 1 s ×U 1 c ×U 1 b ×U 1 t которая совпадает с наблюдаемой симметрией изоспина странности щарма красоты прелести и верха истины Анализ группы перенормировки показывает что предложенная модель временно свободная Вычисляются траектории Редже в старшем логарифмическом приближении Также показывается что все фундаментальные фермионы которые могут быть взяты либо в векторном либо в сопряженном представлении также реджеизованы Вследствие временной свободы предложенмая модель обладает свойствамиUnanalisi degli eventi sperimentali nelle interazioni degli adroni ad alta e bassa energia e dei risultati teorici nella teoria del campo di gauge porta alla conclusione che il modello del campo di gaugeSU6 totalmente spontaneamente infranto temporaneamente libero è un candidato naturale per una descrizione delle interazioni adroniche forti Il modello si basa sui mesoni vettoriali dotati di massa e fermioni osservati Si dimostra che il settore di Higgs può essere scelto in maniera tale che—anche dopo una totale rottura della simmetriaSU6—rimane una simmetria globaleSU2×U 1 s ×U 1 c ×U 1 b ×U 1 t che coincide con losservata simmetria di isospin stranezza charm beauty e top Lanalisi del gruppo di rinormalizzazione indica che il modello è temporaneamente libero Si dimostra che tutti i mesoni vettoriali reggeizzano e le loro traiettorie di Regge progenitrici e figlie si calcolano con lapprossimazione del logaritmo principale Si dimostra anche che tutti i fermioni fondamentali sia in rappresentazione vettoriale che aggiunta reggeizzano A causa della libertà temporanea il modello possiede le proprietà di scala e permette unanalisi perturbativa dei processi ad alta energia Poiché il modello si basa su adroni osservati lanalisi del processo esclusivo è notevolmente facilitata Si dimostra in particolare che il modello prevede una nuova forma di sezione durto totale ad alta energia barionebarione e barioneantibarione è degno di nota che le sezioni durto ottenute diminuiscono ad energie moderatamente alte e aumentano ad energie maggiori in notevole accordo con i dati sperimentali nellintervallo di energia Gevundersetraise03emhboxsmashscriptscriptstylethicksim sqrt s undersetraise03emhboxsmashscriptscriptstylethicksim 30 000 GeV
