Asymptotic Freedom in Parton Language
Guido Altarelli,Giorgio Parisi +1 more
TL;DR: In this article, the main body of predictions of the theory for deep-inleastic scattering on either unpolarized or polarized targets is re-obtained by a method which only makes use of the simplest tree diagrams and is entirely phrased in parton language with no reference to the conventional operator formalism.

Regularization and Renormalization of Gauge Fields
Gerard 't Hooft,M.J.G. Veltman +1 more
TL;DR: In this article, a new regularization and renormalization procedure for gauge theories is presented, which is particularly well suited for the treatment of gauge theories and is transparent when anomalies such as the Bell-Jackiw-Adler anomaly may occur.

Non-Lagrangian Models of Current Algebra
TL;DR: In this article, an alternative to specific Lagrangian models of current algebra is proposed, in which scale invariance is a broken symmetry of strong interactions, as proposed by Kastrup and Mack.

Mass singularities of Feynman amplitudes
TL;DR: In this article, a general method is developed that enables us to determine the degree of divergence of unrenormalized Feynman amplitudes at such singularities, which is also applied to the determination of mass dependence of a total transition probability.

Degenerate Systems and Mass Singularities
T. D. Lee,Michael Nauenberg +1 more
TL;DR: In this paper, it was shown that under certain general conditions such singularities do not appear in the power series expansions of the transition probabilities, provided these are averaged over an appropriate ensemble of degenerate states.
