Discriminating between technicolor and warped extra dimensional model via pp ZZ channel
We explore the possibility to discriminate between certain strongly-coupled
technicolor (TC) models and warped extra-dimensional models where the Standard
Model fields are propagating in the extra dimension. We consider a generic
QCD-like TC model with running coupling as well as two TC models with walking
dynamics. We argue that due to the different production mechanisms for the
lowest-lying composite tensor state in these TC theories compared to the first
Kaluza-Klein graviton mode of warped extra-dimensional case, it is possible to
distinguish between these models based on the angular analysis of the
reconstructed longitudinal Z bosons in the four charged
leptons channel.Comment: 16 pages, 3 figures, 1 tabl
TYC 1031 01262 1: The First Known Galactic Eclipsing Binary with a Type II Cepheid Component
We present the discovery and CCD observations of the first eclipsing binary
with a Type II Cepheid component in our Galaxy. The pulsation and orbital
periods are found to be 4.1523 and 51.38 days, respectively, i.e. this variable
is a system with the shortest orbital period among known Cepheid binaries.
Pulsations dominate the brightness variations. The eclipses are assumed to be
partial. The EB-subtype eclipsing light curve permits to believe that the
binary's components are non-spherical.Comment: 3 pages, 3 figures, accepted to MNRAS Letter
Constraints on Conformal Windows from Holographic Duals
We analyze a beta function with the analytic form of
Novikov-Shifman-Vainshtein-Zakharov result in the five dimensional
gravity-dilaton environment. We show how dilaton inherits poles and fixed
points of such beta function through the zeros and points of extremum in its
potential. Super Yang-Mills and supersymmetric QCD are studied in detail and
Seiberg's electric-magnetic duality in the dilaton potential is explicitly
demonstrated. Non-supersymmetric proposals of similar functional form are
tested and new insights into the conformal window as well as determinations of
scheme-independent value of the anomalous dimension at the fixed point are
presented.Comment: Fig. 5b is corrected to match the discussion in the tex
The algebraic hyperstructure of elementary particles in physical theory
Algebraic hyperstructures represent a natural extension of classical
algebraic structures. In a classical algebraic structure, the composition of
two elements is an element, while in an algebraic hyperstructure, the
composition of two elements is a set. Algebraic hyperstructure theory has a
multiplicity of applications to other disciplines. The main purpose of this
paper is to provide examples of hyperstructures associated with elementary
particles in physical theory.Comment: 13 page
