Radiative neutralino production in low energy supersymmetric Models. II. The case of beam polarization
We study the production of the lightest neutralinos in the radiative process
in low energy supersymmetric
models for the International Linear Collider energies with longitudinally
polarized electron and positron beams. For this purpose we consider the case of
nonminimal supersymmetric standard model as well as the case of minimal
supersymmetric standard model. At the first stage of a linear collider, with
GeV, the radiative production of the lightest neutralinos may
be a viable channel to study supersymmetric partners of the Standard Model
particles, especially if the other supersymmetric particles are too heavy to to
be pair-produced. We consider in detail the effect of beam polarization on the
production cross section. We compare and contrast the dependence of the signal
cross section on the parameters of the neutralino sector of the nonminimal and
minimal supersymmetric standard model when the electron and positron beams are
longitudinally polarized. In order to assess the feasibility of experimentally
observing the radiative neutralino production process, we consider the
background to this process coming from the Standard Model process with longitudinally polarized electron and positron beams.
We also consider the supersymmetric background to the radiative neutralino
production process coming from the radiative production of the scalar partners
of the neutrinos (sneutrinos) ,
with longitudinally polarized beams. This process can be a a background to the
radiative neutralino production when the sneutrinos decay invisibly.Comment: 20 pages, 16 figures, 13 tables; latex problem fixe
Building Reusable Software Component For Optimization Check in ABAP Coding
Software component reuse is the software engineering practice of developing
new software products from existing components. A reuse library or component
reuse repository organizes stores and manages reusable components. This paper
describes how a reusable component is created, how it reuses the function and
checking if optimized code is being used in building programs and applications.
Finally providing coding guidelines, standards and best practices used for
creating reusable components and guidelines and best practices for making
configurable and easy to use.Comment: 9 pages, 6 figure
Development of Low Temperature and High Magnetic Field X-Ray Diffraction Facility
The current progress of materials science regarding multifunctional materials
(MFM) has put forward the challenges to understand the microscopic origin of
their properties. Most of such MFMs have magneto-elastic correlations. To
investigate the underlying mechanism, it is therefore essential to investigate
the structural properties in the presence of magnetic field. Keeping this in
view low temperature and high magnetic field (LTHM) powder x-ray diffraction
(XRD), a unique state-of-art facility in India has been developed at CSR
Indore. This setup works on symmetric Bragg Brentano geometry using a parallel
incident x-ray beam from a rotating anode source working at 17 kW. Using this
one can do structural studies at non-ambient conditions i.e. at low-
temperatures (2-300 K) and high magnetic field (+8 to -8 T). The available
scattering angle ranges from 5{\deg} to 115{\deg} 2{\theta} with a resolution
better than 0.1{\deg}. The proper functioning of the setup has been checked
using Si sample. The effect of magnetic field on the structural properties has
been demonstrated on Pr0.5Sr0.5MnO3 sample. Clear effect of field induced phase
transition has been observed. Moreover, the effect of zero field cooled and
field cooled conditions is also observed.Comment: DAE-SSPS-2014, AIP Conf.Proc. (2015) (accepted), 4 Pages, 2 figure
