Effective Dual Higgs Model with a Dipole-Type Field

The dual Higgs model is reformulated in terms of two-point Wightman functions with the equations of motion involving higher derivatives. In the system of the test color charges an analytic expression for the string tension is derived.Comment: 7 pages, latex, no figures, no tables; talk at XXIII International Colloquium on Group Theoretical Methods in Physics (Dubna 31.07 - 5.08, 2000

BEC and the particle mass

We derive new features of Bose-Einstein correlations by means of Quantum Field Theory at finite temperature, supplemented by operator-field evolution approach. The origin of the dependence of the measured two-particle correlation function (as well as the so-called correlation radius) on the particle mass has received its correct explanation. The lower bound on the particle emitting source size is estimated.Comment: 11 page

LHC signatures of unparticles in decays of Z′Z^{\prime}

We investigate the rare radiative decays of extra gauge neutral bosons. In particular, we established the theoretical predictions for the production of unparticle in decays of $Z^{\prime}$ - bosons. The implementation of our prediction in the analysis at the LHC experiments should be straightforward and lead to more precise determination or limits of unparticle couplings and/or $Z^{\prime}$ couplings and masses.Comment: 15 page

Effective Dual Higgs Mechanism with Confining Forces

We consider the dual Yang-Mills theory which shows some kind of confinement at large distances. In the static system of the test color charges an analytic expression for the string tension is derived.Comment: 6 page

Towards the Bose symmetry violation issue

We study the Bose symmetry violation through the decays of heavy vector bosons at high energies. In particular, the decay of a Z'-boson into two photons where one of the photons is the vector unparticle in the scale invariant sector is considered as a sample. We find out that the Bose symmetry might be violated in the nearly conformal sector at high energy frontier. This may be useful in phenomenological application to the CERN LHC experiments for new physics searches.Comment: 9 page

The RNO framework to the σ\sigma-particle mass

The "standard" iso-singlet scalar particle $\sigma$ is reconsidered in the reduced normal-ordering (RNO) framework to the effective SU(2) theory. Recent reanalysis of the $\pi\pi$-phase shift [1] is used.Comment: LaTeX, 6 pages, no figures and table

New features of two-particle correlations

We show that a recently proposed derivation of Bose-Einstein correlations (BEC) by means of thermal Quantum Field Theory, supplemented by operator-field evolution of Langevin type, allows a deeper understanding of a possible coherent behaviour of the emitting source and a clear identification of the origin of the observed shape of the 2-particle BEC function $C_2(Q)$. We explain the origin of the dependence of the measured correlation radius on the hadron mass. The lower bound of the particle source size is estimated.Comment: 10 pages, 1 figur

Gauge model of unparticles

Modern theoretical models strongly suggest that new phenomena await discovery above the energy scale of the Standard Model (SM) of particle interactions. In this paper we argue that correct description of particle physics in the TeV energy scale needs to account for degrees of freedom obeying the conformal (or scale) invariance. In this respect, the existing of Georgi's unparticles is strongly argued. We present the gauge model of scalar unparticles. The ground state of scalar unparticles in the continuum is restricted by the vacuum expectation value of the SM Higgs boson and the scale dimension $d$. In the framework of Abelian gauge field theories we develop a model in four-dimensional space-time in which the scalar unHiggs is a dipole field. The quantization is performed within the canonical formalism. Based on general principles of quantum field theory the new features of unHiggs propagators are carried out for the first time.Comment: 15 page

Critical point and conformal anomaly

We study the critical point (CP) phenomenon through the increase of fluctuations related to characteristic critical mode. CP would also be identified through the production of primary photons induced by conformal anomaly of strong and electromagnetic interactions. The novel approach to an approximate scale symmetry breaking is developed for this.Comment: 7 page

Does the QGP fire ball really exist?

The strongly interacting matter under extreme conditions of temperature for the conjectured deconfined phase of the quark-gluon plasma is investigated. A systematic study of the form of the thermal ratio of the disorder deviation (TRDD) is presented with the emphasis on the degree of deviation of the TRDD-function from unity. The space-time evolution of quarks and gluons is studied in the framework of two-particle correlation functions to predict the space-time size of the closed deconfined phase.Comment: LaTeX, 18, no figures and table
