The AdS/CFT transformation relates two nonlinear realizations of (super)conformal groups: their realization in the appropriate field theories in Minkowski space with a Goldstone dilaton field and their realization as (super)isometry groups of AdS (super)spaces. It exists already at the classical level and maps the field variables and space-time coordinates of the given (super)conformal field th...

We derive a general quantum master equation for the dynamics of scalar bosonic particle interacting with weak, stochastic and classical external gravitational field. The predicts decoherence in position, momentum energy. show how our reproduces results present literature by taking appropriate limits, thus explaining apparent contradiction their dynamical description. Our result is relevant ligh...

We show that N = 8 self-dual supergravity theory, which is the consistent background for N = 2 closed superstring theory in 2 + 2-dimensions, can accommodate the recently discovered two-dimensional dilaton gravity black hole solution, via appropriate dimensional reductions and truncations. Interestingly, the usual dilaton field in this set of solutions emerges from the scalar field in the 70-di...

We present a manifestly SO(8) invariant non-linear Lagrangian for describing the non-abelian dynamics of the bosonic degrees of freedom of N coinciding M2 branes in flat spacetime. The theory exhibits a gauge symmetry structure of the BF type (semidirect product of SU(N) and translations) and at low energies it reduces exactly to the bosonic part of the Lorentzian BaggerLambert Lagrangian for g...

This identity is preserved if supersymmetry is broken by soft terms, i.e. gaugino/scalar masses, and bi/tri-linear couplings between scalar fields. The relation is crucial for the natural extension of the theory from the electroweak scale to the Planck-scale without introducing quadratic divergences, which are generated in the squark propagator, for instance, by the bosonic squark/gluon loops a...

A consistent description of spin within a QCD string theory has been sought for many years. The addition of dynamical spin to the bosonic string led to the development of supersymmetry and superstring theory [1]. Such theories are more realistic as unified theories of elementary particle physics than as phenomenological descriptions of hadronic states. A more realistic description of hadronic s...

We investigate the indirect generation of the partial width of the ω(782) meson with respect to the reaction ω(782) → ρ(770)π → π+π−π0 within the context of a “Unitary Effective Resonance Model” (UERM), which has previously been applied to resonant fermionic field operators, here extended to scalar, pseudoscalar and vector bosonic fields. The ω(782) meson is described by a (quasi-)real field, w...

Motivated by the ongoing discussion about a seeming asymmetry in the performance of fermionic and bosonic replicas, we present an exact, nonperturbative approach to both fermionic and bosonic zero-dimensional replica field theories belonging to the broadly interpreted beta=2 Dyson symmetry class. We then utilize the formalism developed to demonstrate that the bosonic replicas do correctly repro...
