Colour gluons and scaling in a unified gauge model
Deep inelastic weak and electromagnetic processes are considered within the parton framework taking the partons to be integrally charged quarks and coloured gluons. Despite the participation of the spin-one gluons in these processes, scaling is shown to be maintained by treating the problem in a unified gauge model based on the groupSU (3)colour⊗SUL (2)⊗U(1). This is a consequence of the vector-dominance type of couplings between the gluons and the weak or electromagnetic vector bosons which are induced by the spontaneous breakdown of gauge symmetry. As a further consequence it is found that in the asymptotic region far above the gluon masses the colour octet parts of the weak and electromagnetic currents of the quarks are damped so that, in particular, the integrally charged quarks behave as fractionally charged quarks in this region.

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.

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.

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.

A GAUSSIAN APPROACH TO SINE GORDON THEORY AT FINITE TEMPERATURE
We evaluate the gaussian effective potential (GEP) for the Sine Gordon theory at finite temperature. Using the GEP we find a critical temperature (Tc) such that for all T≥Tc, soliton solutions in this model cease to exist. The zero temperature situation has also been analysed and it has been shown that for λ≥λc, solitons do not exist.

Comment on “A novel class of isospectral deformations in supersymmetric quantum mechanics” by B. Jensen, JHEP 11(2011)059
A bstractWe re-examine the deformation of supersymmetric quantum mechanics considered in ref [1] and show that it is identically same as the deformation considered earlier by a number of authors [2-4].

Motion of a spin-½ particle in shape invariant scalar and magnetic fields
We study the motion of a spin-½ particle in a scalar as well as a magnetic field within the framework of supersymmetric quantum mechanics. We also introduce the concept of shape invariant scalar and magnetic fields and it is shown that the problem admits exact analytical solutions when such fields are considered.

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.
