Summary
The evolution of masses with a scaleM is investigated in scalar and pseudoscalar gluon theories for the comparison with QCD. The scalar theory shows the increase of effective masses withM, and, therefore, it cannot be a candidate for the theory of strong interactions. In pseudoscalar gluon theory effective masses become lighter at higherM, just like in QCD.
Riassunto
Si analizza l’evoluzione di masse con una scalaM nelle teorie di gluoni pseudoscalari e scalari in confronto con la QCD. La teoria scalare mostra l’incremento conM delle masse effettive, e quindi non può essere candidata alla teoria delle interazioni forti. Nella teoria del gluone pseudoscalare le masse effettive diventano piú leggere perM maggiore proprio come nella QCD.
Реэюме
Исследуется зволюция масс с величиной масщтабаM в скалярной и псевдоскалярной глюонной теориях для сравнения с квантовой хромодинамикой. Скалярная теория укаэывает на увеличение зффективных масс сM и, следовательно, зта теория не может быть кандидатом для теории сильных вэаимодействий. В псевдоскалярной глюонной теории зффективные массы становятся легче при больщихM, точно так же как в квантовой хромодинамике.
