On the Mass of the Dark Compact Halo Objects
Philippe Jetzer, Eduard Masso
Recently the French EROS collaboration and the American-Australian MACHO collaboration have reported the observation of altogether three possible microlensing events by monitoring…
Photon-Photon Scattering at the Photon Linear Collider
G. Jikia, A. Tkabladze
Photon-photon scattering at the Photon Linear Collider is considered. Explicit formulas for helicity amplitudes due to boson loops are presented. It is shown that photon-photon…
Dynamical Determination of the Metric Signature in Spacetime of Nontrivial Topology
E. Elizalde, S. D. Odintsov, A. Romeo
The formalism of Greensite for treating the spacetime signature as a dynamical degree of freedom induced by quantum fields is considered for spacetimes with nontrivial topology of…
Pair Production at the Photon Linear Collider
G. Jikia, A. Tkabladze
scattering at the Photon Linear Collider is considered. Explicit formulas for helicity amplitudes due to boson loops are presented. It is shown that the pair pro…
One-Loop Renormalization of Higher-Derivative 2D Dilaton Gravity
E. Elizalde, S. Naftulin, S. D. Odintsov
A theory of higher-derivative 2D dilaton gravity which has its roots in the massive higher-spin mode dynamics of string theory is suggested. The divergences of the effective action…
New series of 3D lattice integrable models
V. V. Mangazeev, S. M. Sergeev, Yu. G. Stroganov
In this paper we present a new series of 3-dimensional integrable lattice models with colors. The case generalizes the elliptic model of our previous paper. The weight fu…
Ising Model Universality for Two-Dimensional Lattices
W. Janke, M. Katoot, R. Villanova
We use the single-cluster Monte Carlo update algorithm to simulate the Ising model on two-dimensional Poissonian random lattices of Delaunay type with up to 80\,000 sites. By apply…
Near Future Perpectives of QCD Spin Studies
P. M. Nadolsky, S. M. Troshin, N. E. Tyurin
We consider the physics motivations and perspectives for the study of spin phenomena at the future high energies accelerators. The possibilities to use the already operating machin…
Particle Mechanics Models with W-symmetries
J. Gomis, J. Herrero, K. Kamimura +1
We introduce a particle mechanics model with Sp() gauge invariance. Different partial gauge-fixings by means of sl(2) embeddings on the gauge algebra lead to reduced models whi…
The Canonical Symmetry for Integrable Systems
A. N. Leznov, A. V. Razumov
The properties of discrete nonlinear symmetries of integrable equations are investigated. These symmetries are shown to be canonical transformations. On the basis of the considered…
Semiclassical Equations for Weakly Inhomogeneous Cosmologies
Antonio Campos, Enric Verdaguer
The in-in effective action formalism is used to derive the semiclassical correction to Einstein's equations due to a massless scalar quantum field conformally coupled to small grav…
Beyond the black disk limit
S. M. Troshin, N. E. Tyurin
We consider consequences of violation of the black disk limit possibly revealed by the new CDF measurements of the total, elastic and diffractive cross--sections.
Dirac sheets and gauge fixing in lattice gauge theory
V. G. Bornyakov, V. K. Mitrjushkin, M. Müller-Preussker +1
Photon correlators in pure gauge theory for different lattice actions are considered under the Lorentz gauge condition. They are shown to depend strongly on the gauge fixi…
Renormalizabilty of TH Heavy Quark Effective Theory
E. Bagan, P. Gosdzinsky
We show that the Heavy Quark Effective Theory is renormalizable perturbatively. We also show that there exist renormalization schemes in which the infinite quark mass limit of any…
Dirac versus reduced phase space quantization for systems admitting no gauge conditions
Mikhail S. Plyushchay, Alexander V. Razumov
The constrained Hamiltonian systems admitting no gauge conditions are considered. The methods to deal with such systems are discussed and developed. As a concrete application, the…
--Geometry and Associated Continuous Toda System
Mikhail V. Saveliev, Svetlana A. Savelieva
We discuss an infinite--dimensional kählerian manifold associated with the area--preserving diffeomorphisms on two--dimensional torus, and, correspondingly, with a continuous limit…
Elliptic solution for modified tetrahedron equations
V. V. Mangazeev, Yu. G. Stroganov
As is known, tetrahedron equations lead to the commuting family of transfer-matrices and provide the integrability of corresponding three-dimensional lattice models. We present the…
Boundary values as Hamiltonian variables. I. New Poisson brackets
Vladimir O. Soloviev
The ordinary Poisson brackets in field theory do not fulfil the Jacobi identity if boundary values are not reasonably fixed by special boundary conditions. We show that these brack…
The Integrable Mapping as the Discrete Group of Inner Symmetry of Integrable Systems
D. B. Fairlie, A. N. Leznov
It is shown that each integrable mapping is connected with a hierarchical completely integrable sytem of equations of evolution type which are invariant with respect to the transfo…
On the Logarithmic Triviality of Scalar Quantum Electrodynamics
M. Baig, H. Fort, S. Kim +2
Using finite size scaling and histogram methods we obtain numerical results from lattice simulations indicating the logarithmic triviality of scalar quantum electrodynamics, even w…
Extra symmetries in the effective theory of heavy quarks
J. Soto, R. Tzani
Extra symmetries are shown to exist in the effective theory of heavy quarks when both quarks and anti-quarks with the same velocity are included. These symmetries mix the quark wit…
Renormalization Group Approach to Matrix Models in Two-Dimensional Quantum Gravity
Carles Ayala
We explore the implications of recent work by Brézin and Zinn-Justin, applying the renormalization group techniques from critical phenomena to the scaling limit of matrix models in…
Constituent Quark Couplings and QCD in the Large Limit
Santiago Peris, Eduardo de Rafael
It is shown that in the constituent quark model of Georgi-Manohar, the dispersion relation that leads to the Adler-Weisberger sum rule for the axial vector coupling requires…
