Spotting Glueballs in Collinear Gluon Jets
Abstract We suggest looking for pure gluon hadronic states (glueballs) in ϒ→ 3g → low spherically final state (collinear gluon jets). In these events one gluon has the maximum energy, Mϒ 2 , favouring fragmentation into a glueball. The signature for a true C = G + glueball is its prominence at the ϒ resonance in e + e − →ϒ → (glueball → four charged pions) + … and its absence in q q jets off (we do not expect significant quark fragmentation into glueballs).

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.

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.

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.

DARBOUX TRANSFORMATION FOR THE ONE-DIMENSIONAL STATIONARY DIRAC EQUATION WITH NON-HERMITIAN INTERACTION
The Darboux algorithm is applied to an exactly solvable one-dimensional stationary Dirac equation, with non-Hermitian, pseudoscalar interaction V0(x). This generates a hierarchy of exactly solvable Dirac Hamiltonians, , defined by new non-Hermitian interactions V1(x), which are also pseudoscalar. It is shown that are isospectral to the initial Hamiltonian h0, except for certain missing states.

Non-linear coherent states associated with conditionally exactly solvable problems
Abstract Recently, based on a supersymmetric approach, new classes of conditionally exactly solvable problems have been found. These systems exhibit a symmetry structure characterized by non-linear algebras. In this paper the associated “non-linear” coherent states are constructed and some of their properties are discussed in detail.

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.

Magnetic point vortex and parasupersymmetry
Abstract We develop a formalism for point vortex interaction in parasupersymmetry. It is shown that vortices are compatible with parasupersymmetry and there are zero range interactions in some low angular momentum states.
