Probe of anomalous quartic couplings in the photon-photon collisions
In this paper, we examine the potentials of the processes and at the CLIC with
and TeV to investigate anomalous quartic
couplings by two different CP-violating and CP-conserving effective
Lagrangians. We find confidence level limits on the anomalous coupling
parameters at the three CLIC energies and various integrated luminosities. The
best limits obtained from the process
on the anomalous ,
and couplings
defined by CP-conserving effective Lagrangians are GeV, and GeV, while coupling
determined by CP-violating effective Lagrangians is obtained as GeV. In addition, the best limits derived on
, and
and from the
process are obtained as
GeV, GeV, and GeV, respectively.Comment: 33 pages, 27 figures, 4 tables, version to appear in JHE
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
A simple model potential for hollow nanospheres
A new model potential is introduced to describe the hollow nanospheres such
as fullerene and molecular structures and to obtain their electronic
properties. A closed analytical solution of the corresponding treatment is
given within the framework of supersymmetric perturbation theory.Comment: 7 pages, 3 figure
