Quark-lepton complementarity with quasidegenerate Majorana neutrinos
A basis independent formulation of quark-lepton complementarity is implemented at a high scale for quasidegenerate Majorana neutrinos. It is shown that even with the renormalization group evolution in the minimal supersymmetric standard model, the scenario can be consistent with the data provided a nontrivial role is played by the Majorana phases. Correlated constraints are found on these phases and the neutrino mass scale using the current data. We also indicate how future accurate measurements of the mixing angles can serve as tests of this scenario and restrict the values of the Majorana phases.

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.

Non-Hermitian Quantum Mechanics with Minimal Length Uncertainty
We study non-Hermitian quantum mechanics in the presence of a minimal length. In particular we obtain exact solutions of a non-Hermitian displaced harmonic oscillator and the Swanson model with minimal length uncertainty. The spectrum in both the cases are found to be real. It is also shown that the models are pseudo-Hermitian and the metric operator is found explicitly in both the cases.

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.

Higher order intertwining approach to quasinormal modes
Using higher order intertwining operators we obtain new exactly solvable potentials admitting quasinormal mode (QNMs) solutions of the Klein–Gordon equation. It is also shown that different potentials exhibiting QNMs can be related through nonlinear supersymmetry.

Conditionally Exactly Solvable Potentials: A Supersymmetric Construction Method☆
Abstract We present in this paper a rather general method for the construction of so-called conditionally exactly solvable potentials. This method is based on algebraic tools known from supersymmetric quantum mechanics. Various families of one-dimensional potentials are constructed whose corresponding Schrodinger eigenvalue problem can be solved exactly under certain conditions of the potential parameters. Examples of quantum systems on the real line and the half line as well as on some finite interval are studied in detail.

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.
