Deformed Oscillator Algebras and Higher-Spin Gauge Interactions of Matter Fields in 2+1 Dimensions
Mikhail Vasiliev
We formulate a non-linear system of equations which describe higher-spin gauge interactions of massive matter fields in 2+1 dimensional space-time and explain some properties of th…
Covariance of WDVV equations
A. Mironov, A. Morozov
The (generalized) WDVV equations for the prepotentials in topological and Seiberg-Witten models are covariant with respect to non-linear transformations, described in t…
Quantum Decoherence and Weak Localization at Low Temperatures
Dmitrii S. Golubev, Andrei D. Zaikin
We develope a theory of a fundamental effect of the interaction-induced decoherence of the electron wave function in a disordered metal. With the aid of the Keldysh technique and t…
Quantum singular oscillator as a model of two-ion trap: an amplification of transition probabilities due to small time variations of the binding potential
V. V. Dodonov, V. I. Man'ko, L. Rosa
Following the paper by M. Combescure [Ann. Phys. (NY) 204, 113 (1990)], we apply the quantum singular time dependent oscillator model to describe the relative one dimensional motio…
Past the Highest-Weight, and What You Can Find There
A M Semikhatov
The properties of highest-weight representations of the N=2 superconformal algebra in two dimensions can be considerably simplified when re-expressed in terms of relaxed ^sl(2) rep…
Embedding Diagrams of N=2 Verma Modules and Relaxed ^sl(2) Verma Modules
A M Semikhatov, V A Sirota
We classify and explicitly construct the embedding diagrams of Verma modules over the N=2 supersymmetric extension of the Virasoro algebra. The essential ingredient of the solution…
Nonperturbative Violation of Factorial Moments Scaling in Dissipative QCD jets
A. V. Leonidov, D. M. Ostrovsky
The nonperturbative modification of the evolution equation for QCD generating functional is applied to the analysis of the factorial moments of the intrajet particle distributions…
Hadron Polarizabilities and Form Factors
D. Drechsel, J. Becker, A. Z. Dubnickova +17
This is the summary of the working group on Hadron Polarizabilities and Form Factors of the Chiral Dynamics Workshop in Mainz, September 1-5, 1997.
Quantum Dirac constraints, Ward identities and path integral in relativistic gauge
A. O. Barvinsky
Quantum Dirac constraints in generic constrained system are solved by directly calculating in the one-loop approximation the path integral with relativistic gauge fixing procedure.…
Cosmological waveguides for gravitational waves
G. Bimonte, S. Capozziello, V. Man'ko +1
We study the linearized equations describing the propagation of gravitational waves through dust. In the leading order of the WKB approximation, dust behaves as a non-dispersive, n…
Particles and Nuclei as Quantum Slings
I. M. Dremin, V. I. Manko
Rotation of such objects as an atomic nucleus or a chromodynamical string can result in specific effects in scattering processes and multiparticle production. Secondary fragments o…
On Event-by-Event Fluctuations in Nuclear Collisions
Marek Gazdzicki, Andrei Leonidov, Gunther Roland
We demonstrate that a new type of analysis in heavy-ion collisions, based on an event-by-event analysis of the transverse momentum distribution, allows us to obtain information on…
Solution of quantum Dirac constraints via path integral
A. O. Barvinsky
The semiclassical solution of quantum Dirac constraints in generic constrained system is obtained by directly calculating in the one-loop approximation the gauge field path integra…

A. Marshakov, A. Mironov
We discuss and supersymmetric gauge theories in the target-space with compactified directions and with the matter hypermultiplets in fundamental representations in the fr…
Photo-production of psi' Mesons at HERA
C. Adloff
Quasi-elastic (z >0.95) photo-production of psi' mesons has been observed at HERA for photon-proton centre-of-mass energies in the range 40 to 160 GeV. The psi' mesons were identif…
Line emission from an accretion disk around black hole: effects of the disk structure
Vladimir I. Pariev, Benjamin C. Bromley
The observed iron K-alpha fluorescence lines in Seyfert galaxies provide strong evidence for an accretion disk near a supermassive black hole as a source of the line emission. Prev…
Gravitational Capture of Cosmic Strings by a Black Hole
Jean-Pierre De Villiers, Valeri P. Frolov
The gravitational interaction of an infinitely long cosmic string with a Schwarzschild black hole is studied. We consider a straight string that is initially at a great distance an…
Wheeler-DeWitt equation and Feynman diagrams
A. O. Barvinsky, C. Kiefer
We present a systematic expansion of all constraint equations in canonical quantum gravity up to the order of the inverse Planck mass squared. It is demonstrated that this method g…
Gauge Invariance of QED
I. V. Tyutin, Vad. Yu. Zeitlin
The problem of gauge invariance of the physical sector of (2+1)-dimensional Maxwell-Chern-Simons quantum electrodynamics (QED) is studied. It is shown that using Proca mass…
SUSY field theories, integrable systems and their stringy/brane origin -- II
A. Gorsky, S. Gukov, A. Mironov
Five and six dimensional SUSY gauge theories, with one or two compactified directions, are discussed. The 5d theories with the matter hypermultiplets in the fundamental representat…
Vector Meson Production at a Polarized HERA Collider
S. P. Baranov, M. G. Ryskin, T. Gehrmann
A successful interpretation of the cross sections for elastic and inelastic vector meson production can be made if one assumes the underlying dynamics to be governed by hard parton…
