Showing papers on "Naturalness published in 1983"


Journal ArticleDOI
TL;DR: In this paper, it was shown that spontaneously broken N = 1 supergravity can lead to an effective low-energy theory which is phenomenologically acceptable, and the naturalness condition that the low energy superpotential be scale invariant is imposed.

TL;DR: This discussion will attempt to exploit a distinction to be drawn between a priori structures of illocutionary actions in the service of formulat?
Abstract: This discussion will attempt to exploit a distinction to be drawn between con? tingent and a priori structures of illocutionary actions in the service of formulat? ing a response to the following problem: to what extent, if at all, do claims for the conventionality of any given, identified sequential arrangement of utterances arising in natural conversational interaction depend upon statistical arguments? Given that there are indefinitely many conversations going on in the world, how are serious analytical claims for the "naturalness" or "organizational priority" of specific sequential arrangements to be justified? I shall propose that two major sorts of analytical findings advanced within the sequential analysis of discourse need to be brought into clearer focus. One type of finding is concerned with the specification of empirically contingent organiza? tions of utterances for vernacularly-defined sequence-types such as "request sequences," "trouble sequences," "complaint sequences" and the like. These findings characteristically take the shape of exhibiting a local orderliness to inter (and intra-) utterance relations without strong claims for distributive scope across a set. Where such a distributive claim is advanced it is usually based upon having discovered closely similar sequential arrangements in some corpus of intuitively defined "like cases," and the warrant for the claim for conventionality is weak inductive evidence. On the other hand, by far the strongest arguments have been advanced for the more "abstract" structures which may be evident in materials of a vast variety and which do not appear to be restricted in their occurrence to vernacularly-defined sequence-types of any specific sort. Claims for their con? ventionality appear to be much stronger and relatively impervious to demands for their statistical distribution as a basis for grounding. In other words, whilst analysts may be vulnerable to the charge of weak inductive support for the generality they claim for some contingent sequential arrangements proposed to

TL;DR: Although non-perturbative study of field theories has a long history, it is a feeling shared by many people, perhaps by all of us at this workshop, that it is becoming increasingly more critical for the deep understanding of physical laws of nature as discussed by the authors.
Abstract: Although non-perturbative study of field theories has a long history, It is a feeling shared by many people, perhaps by all of us at this workshop, that it is becoming increasingly more critical for the deep understanding of physical laws of nature. It is probably not an exaggeration to say that it is an emblem of the particle physics of the 80’s. This I believe is an inevitable trend. The development of non-abelian gauge theories In the 70’s has brought us to the stage where we cannot help talking about the derivation of the spectrum of the world with naturalness and economy (unification). This is outside the realm of the perturbation theory, in which one particle requires one field with prescribed characteristics. More dynamical aspects of gauge theories must be understood, and QCD and supersymmetric versions of it will certainly play primary roles as prototypical theories.

TL;DR: In this paper, it was shown that very low energy unification and neutron-antineutron oscillations in grand unified theories are incompatible with the naturalness of the Yukawa couplings and the masses of the Higgs scalars.
