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

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
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 - 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
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 -particle mass
The "standard" iso-singlet scalar particle is reconsidered in the
reduced normal-ordering (RNO) framework to the effective SU(2) theory. Recent
reanalysis of the -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 . 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 . 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
Two-Photon Correlations in Collisions
It is well understood that the studies of correlations between produced
particles, the effects of coherence and chaoticity, an estimation of particle
emitting source size play an important role in high energy physics [1]. First
of all, we mean the investigation of the space-time extension or even squeezing
of particle sources via the multiparticle quantum-statistics correlation. We
consider the two-photon correlation function that can provide the space-time
information about the Higgs-boson source in thermal environment and estimate
the Higgs-boson mass for the first time.Comment: 12 page
