Summary

Supersymmetric interacting models, like the two-dimensionalN=1 Wess-Zumino model andN=2 Yang-Mills theory, are constructed on the space lattice. The Becher-Joos techniques, for the Dirac-Kähler formulation on the lattice, are extensively used in order to obtain the supercurrents and Hamiltonians on the lattice, even in the interacting case. We show that it is possible to construct the invariant actions for these models with the correct classical continuum limit. Our work is based on the new method of putting the fields in the adjoint representations on the lattice.

Riassunto

Si costruiscono modelli d'interazione supersimmetrici, come il modello bidimensionale di Wess-Zumino perN=1 e la teoria di Yang-Mills perN=2, sul reticolo dello spazio. Le tecniche di Becher-Joos, per la formulazione di Dirac-Kähler sul reticolo, sono usate estensivamente per ottenere le supercorrenti e le hamiltoniane sul reticolo, anche nel caso d'interazione. Si mostra che è possibile costruire le azioni invarianti per questi modelli con limite corretto classico nel continuo. Il nostro lavoro è basato sul nuovo metodo di situare i campi nelle rappresentazioni aggiunte sul reticolo.

Резюме

На пространственной решетке конструируются суперсимметричные модели взаимодействия, подобные двумернойN=1 модели Весса-Зумино иN=2 теории Янга-Миллса. Используется техника Бечера-йоса для формулировки Дирака-Кахлера на решетке, чтобы получить супертоки и Гамильтонианы на решетке в случае взаимодействия. Показывается, что возможно сконструировать инвариантные действия для этих моделей с правильным классическим непрерывным пределом. Наш подход основан на новом методе выражения полей в сопряженных представлениях на решетке.
