Role of parton transverse momenta in polarized deep inelastic scattering
Abstract The transverse momenta of quark partons are shown to significantly dilute the moderate- Q 2 broken-SU (6) constraints on the leading spin-dependent deep inelastic electromagnetic structure function of the proton. A realistic calculation of the latter is performed incorporating these effects as well as those of the quantum chromodynamic evolution to higher Q 2 .

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.

Bound state in continuum-like solutions in one-dimensional heterostructures
Abstract We examine the one-dimensional Dirac equation with modulated or position-dependent velocity. In particular, it is shown that using suitable velocity profiles it is possible to create bound state in continuum (BIC)-like as well as discrete energy bound state solutions.

On supersymmetry breaking in a strong magnetic field
Using Schwinger's proper time formalism, the author constructs the one-loop effective potential for a supersymmetric non-Abelian gauge theory in a background constant magnetic field and study supersymmetry breaking in the strong-field approximation. The problem of symmetry restoration in non-supersymmetric gauge theory is also discussed.

Comment on the ''Effect of a strong magnetic field and high temperature on broken gauge theories''
In a recent paper Chakrabarti has examined the effects of a strong magnetic field and high temperature on spontaneously broken gauge theories. We point out the invalidity of the approximation he has used to evaluate the one-loop effective potential. Using a rigorous and improved method, we obtain a result different from Chakrabarti's result. Further using this method we extend the results of the aforementioned paper by including fermions in the theory.

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.
