Type IIB GreenSchwarz superstring in plane wave RamondRamond background
 Nucl. Phys. B
"... We construct the covariant κsymmetric superstring action for type IIB superstring on plane wave space supported by RamondRamond background. The action is defined as a 2d sigmamodel on the coset superspace. We fix the fermionic and bosonic lightcone gauges in the covariant GreenSchwarz superstri ..."

Search For A New Gauge Boson In
"... A search was made for a new light gauge boson X which might be produced in ß 0 ! fl +X decay from neutral pions generated by 450GeV protons in the CERN SPS neutrino target. The X's would penetrate the downstream shielding and be observed in the NOMAD detector via the Primakoff effect, in th ..."

Gravity coupled with matter and the foundation of non commutative geometry
, 1996
"... We first exhibit in the commutative case the simple algebraic relations between the algebra of functions on a manifold and its infinitesimal length element ds. Its unitary representations correspond to Riemannian metrics and Spin structure while ds is the Dirac propagator ds = ×— × = D −1 where D i ..."

The internal fluctuations of the non commutative geometry are trivial in the commutative case but yield the full bosonic sector of SM with all correct quantum numbers in the slightly non commutative case.

Decays of a Leptophobic Gauge Boson ∗

"... We discuss the theory and phenomenology of decays of a leptophobic U(1) gauge X boson X, such as has been proposed to explain the alleged deviations of Rb and Rc from standard model predictions. If the scalars involved in the breaking of the SU(2) × U(1) symmetry are sufficiently light, X will some ..."

Massless Black Holes and Conifolds in String Theory
"... Lowenergy effective field theories arising from CalabiYau string compactifications are generically inconsistent or illdefined at the classical level because of conifold singularities in the moduli space. It is shown, given a plausible assumption on the degeneracies of black hole states, that for ..."

, that for type II theories this inconsistency can be cured by nonperturbative quantum effects: the singularities are resolved by the appearance of massless RamondRamond black holes. The Wilsonian effective action including these light black holes is smooth near the conifold, and the singularity is reproduced
Lectures on supersymmetric gauge theories and electricmagnetic duality

The kinematics are largely determined by holomorphy and the dynamics are governed by duality. The results shed light on the phases of gauge theories. Some results and interpretations which have not ..."
