Stringent low-energy mass constraints in no-scale supergravity.
Spectacular mass constraints are shown to exist at low energies in minimal no-scale supergravity theories. The top quark cannot be too light, the lowest-lying Higgs particle cannot be too heavy, and the pseudoscalar Higgs boson must weigh nearly a quarter as much as the gluino.

Current-commutators and high energy hadron production in e+e− annihilation
Abstract We consider the asymptotic behavior of the structure-functions for the process e + e − → H + everything (where H is a detectable hadron) in terms of commutators involving the electromagnetic current.

Parton description of the forward peak in single particle electroproduction with highly virtual photons
The parton mode or the reaction eN→eAB (N = nucleon, A, B = hadrons) in the fixed ω Bj limit is used to discuss the width of the corresponding forward peak as a function of the photon mass.

Remarks on the finite temperature effect in supersymmetric quantum mechanics
Using the thermofield dynamics formalism the authors study the effect of temperature on supersymmetry within the context of supersymmetric quantum mechanics. The model considered involves an interaction not of polynomial type and it is shown that the finite-temperature effect causes spontaneous breaking of supersymmetry.

Supersymmetry under the influence of a magnetic field and high temperature
We evaluate the one-loop effective potential in the presence of a strong magnetic field and high temperature for a supersymmetric non-abelian gauge theory and study SUSY breaking at the one-loop level.

SOLUTION OF κ DEFORMED DIRAC EQUATION WITH ANOMALOUS MAGNETIC MOMENT INTERACTION
We construct the deformed Dirac equation with anomalous magnetic moment interaction and solve this equation for a charged particle in the presence of a constant magnetic field.

Quasi-exact solvability of Dirac–Pauli equation and generalized Dirac oscillators
Abstract In this paper we demonstrate that neutral Dirac particles in external electric fields, which are equivalent to generalized Dirac oscillators, are physical examples of quasi-exactly solvable systems. Electric field configurations permitting quasi-exact solvability of the system based on the sl (2) symmetry are discussed separately in the spherical, cylindrical, and Cartesian coordinates. Some exactly solvable field configurations are also exhibited.

On Pseudo-Hermitian Hamiltonians
We investigate some questions on the construction of $\eta$ operators for pseudo-Hermitian Hamiltonians. We give a sufficient condition which can be exploited to systematically generate a sequence of $\eta$ operators starting from a known one, thereby proving the non-uniqueness of $\eta$ for a particular pseudo-Hermitian Hamiltonian. We also study perturbed Hamiltonians for which $\eta$'s corresponding to the original Hamiltonian still work.
