Stringent new bounds on supersymmetric Higgs bosons from existing Tevatron data
Tight limits are derived on models with extended Higgs sectors, including the Minimal Supersymmetric Standard Model (MSSM), by exploiting the data on τ + τ − + 2 jets final states, used by the CDF collaboration to place limits on third generation leptoquarks. The main observation here is that both leptoquark production and associated bb Higgs production can lead to bbτ + τ − final states. For the MSSM we find that CP-odd neutral Higgs boson masses up to 190 GeV are excluded if the ratio of vacuum expectation values tanβ is 50.

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.

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.

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.

On supersymmetry and random sources
We evaluate the one loop effective potential for the supersymmetric Higgs model in the presence of a gaussian random source and examine supersymmetry breaking at the one loop level.

A Variational approach to the Liouville model
We perform a variational analysis of the Liouville model. In particular we evaluate the effective potential and examine the possibility of restoring translation invariance.

SUPERSYMMETRIC APPROACH TO QUASINORMAL MODES
Supersymmetry (SUSY) in quantum mechanics is extended from square integrable states to those satisfying the outgoing wave boundary condition. Using this formalism we obtain new exactly solvable potentials admitting quasinormal modes (QNM) solutions of the Klein–Gordon equation.

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].
