Search for the Anomalous Interactions of Up-Type Heavy Quarks in Collision at the LHC
We investigate the anomalous interactions of heavy up-type quark t' in a
collision at the LHC. We have obtained 95% confidence
level(CL)limit of anomalous coupling by taking into account three
forward detector acceptances: ,, and

Probe of the Anomalous Quartic Couplings with Beam Polarization at the CLIC
We have investigated the anomalous quartic couplings defined by the
dimension-8 operators in semileptonic decay channel of the
process for
unpolarized and polarized electron (positron) beam at the Compact Linear
Collider. We give the confidence level bounds on anomalous
, and
couplings for various values of the integrated
luminosities and center-of-mass energies. The best sensitivities obtained on
anomalous , and
couplings through the process
with beam
polarization at TeV and an integrated luminosity of
fb are GeV, GeV, GeV,
which show improvement over the current bounds.Comment: 8 pages, 7 figures and 8 tables, published versio
Anomalous couplings with beam polarization at the Compact Linear Collider
We study the anomalous couplings at the Compact Linear Collider
through the processes , and is the Weizsacker-Williams
photon). We give the 95\% confidence level limits for unpolarized and polarized
electron (positron) beam on the anomalous couplings for various values of the
integrated luminosities and center-of-mass energies. We show that the obtained
limits on the anomalous couplings through these processes can highly improve
the current experimental limits. In addition, our limits with beam polarization
are approximately two times better than the unpolarized case.Comment: Tables and references adde

The effect of electromagnetic properties of neutrinos on the photon-neutrino decoupling temperature
We examine the impact of electromagnetic properties of neutrinos on the
annihilation of relic neutrinos with ultra high energy cosmic neutrinos for the
process. For this process, photon-neutrino
decoupling temperature is calculated via effective lagrangian model beyond the
standard model. We find that photon-neutrino decoupling temperature can be
importantly reduced below the QCD phase transition with the model independent
analysis defining electromagnetic properties of neutrinos.Comment: 12 pages, 3 figures, published versio
Regulation and competition in the Turkish telecommunications industry: an update
This chapter provides an overview of the state of liberalization, competition and regulation of major segments of the telecommunications industry in Turkey. It shows that the competitive stance of the regulatory authority and the development of actual competition has been uneven across segments. Specifically, the degree of competition has been higher in the mobile segment relative to fixed telephony or broadband. The chapter also discusses the new Electronic Communications Law and argues that although not perfect, it provides a coherent basis on which the regulatory authority can pursue competitive objectives in a more even manner. However, the actual development of competition will depend a lot on how the law and the ensuing secondary legislation are actually implemented
Search for the anomalous and gauge couplings through the process with unpolarized and polarized beams
This work offers the constraints on the anomalous neutral triple gauge
couplings (aNTGC) for the process at the CLIC with
TeV. The realistic CLIC detector environments and their effects
are considered in our analysis. The study is planned for the decays of
producted bosons to a pair of charged leptons (electrons or muons) and
neutrino pairs. The bounds on the aNTGCs defining -conserving
coupling and three -violating
, , and couplings
are obtained. Also, the effects and advantages of polarization for incoming
electron beams in these calculations are investigated.Comment: 21 pages, 14 figure
