Title: On Generalized Quantum Deformations and Symmetries in Quantum Mechanics
Authors: Jules Beckers
Comments: 7 pages, latex, no figures
\\
Supersymmetric and parasupersymmetric quantum mechanics are now recognized as
two further parts of quantum mechanics containing a lot of new informations
enlightening (solvable) physical applications. Both contents are here analysed
in connection with generalized quantum deformations. In fact, the
parasupersymmetric context is visited when the order of paraquantization p is
limited to the first nontrivial value p = 2.

Title: Large-Order Perturbation Theory in Infrared-Unstable Superrenormalizable
Field Theories
Author: John M. Cornwall (UCLA)
Comments: 28 pages, Latex, three .eps figures
Report-no: UCLA/96/TEP/36
\\
We study the factorial divergences of Euclidean $\phi^3_5$, a problem with
connections both to high-energy multiparticle scattering in d=4 and to d=3 (or
high-temperature) gauge theory, which like $\phi^3_5$ is infrared-unstable and
superrenormalizable. At large external momentum p (or small mass M) and large
order N one might expect perturbative bare skeleton graphs to behave roughly
like $N!(ag^2/p)^N$ with a>0, so that no matter how large p is there is an
$N\sim g^2/p$ giving rise to strong perturbative amplitudes. The semi-
classical Lipatov technique (which works only in the presence of a mass) is
blind to this momentum dependence, so we proceed by direct summation of bare
skeleton graphs. We find that the various limits of large N, large p, and small
M do not commute, and that when $N\gg p^2/M^2$ there is a Borel singularity
associated with $g^2/M$, not $g^2/p$. This is described by the zero-momentum
Lipatov technique, and we find the necessary soliton for $\phi^3_5$; the
corresponding sphaleron-like solution for unbroken Yang-Mills theory has long
been known. We also show that the massless theories have no classical solitons.
We discuss non-perturbative effects based partly on known physical arguments
concerning the cancellation by solitons of imaginary parts due to the pert-
urbative Borel singularity, and partly on the dressing of bare skeleton graphs
by dressed propagators showing non-perturbative mass generation, as happens in
d=3 gauge theory.
