Linear programming analysis of the -parity violation within EDM-constraints
The constraint on the -parity violating supersymmetric interactions is
discussed in the light of current experimental data of the electric dipole
moment of neutron, Xe , Tl, and Hg atoms, and YbF and
ThO molecules. To investigate the constraints without relying upon the
assumption of the dominance of a particular combination of couplings over all
the rest, an extensive use is made of the linear programming method in the scan
of the parameter space. We give maximally possible values for the EDMs of the
proton, deuteron, He nucleus, Rn, Ra, Fr, and the
-correlation of the neutron beta decay within the constraints from the
current experimental data of the EDMs of neutron, Xe, Tl, and
Hg atoms, and YbF and ThO molecules using the linear programming
method. It is found that the -correlation of the neutron beta decay and
hadronic EDMs are very useful observables to constrain definite regions of the
parameter space of the -parity violating supersymmetry.Comment: 24 pages, 6 figure
Constraint on R-parity violating MSSM at the one-loop level from CP-odd N-N interaction
Minimal supersymmetric standard model with R-parity violation (RPVMSSM)
contributes to the P-, CP-odd four-quark interaction. The P-, CP-odd four-quark
interaction is constrained by the new 199Hg EDM experimental data. It is then
possible to constrain R-parity violating (RPV) couplings from the 199Hg EDM
data. In this talk, we analyze the RPV contribution to the P-, CP-odd four-
quark interaction at the one-loop level to give constraints on RPV parameters.Comment: To appear in the proceedings of International conference on the

Kenshi’s Experiences of Kendo: A Phenomenological Investigation
The aim of this study was to extend existing literature on the martial arts by examining the experience of kendo (Japanese fencing) participants. In-depth, existential phenomenological interviews were conducted with nine (eight males and one female) currently competitive kendo practitioners (i.e., kenshi), ranging in age from 19 to 40 years. All participants were of Japanese descent but resided in the United States at the time of the interviews. Thematic analysis of the transcripts revealed several prominent aspects of the lives and performance experiences of kenshi. The most important finding was the relatively equal emphasis participants placed on the mastery of kendo technique, aesthetically elegant skill execution, and victory in competition. Other aspects of kenshi’s experience included the building of strong relationships with influential sensei (i.e., instructors), the display of proper manners and etiquette, and the learning of life lessons
R-parity violating supersymmetric contributions to the neutron beta decay at the one-loop level
The contribution of the R-parity violating minimal supersymmetric standard
model to the neutron beta decay at the one-loop level is investigated. It is
found that the baryon number and R-parity violating interactions contribute to
the D correlation through one-loop corrections, while the tree level prediction
is vanishing. The Fierz interference term is also investigated at the one-loop
level by considering the lepton number and R-parity violating interactions. We
show that future experimental progress can provide us with better constraints
on some of the combinations of R-parity violating couplings.Comment: 13 pages, 6 figures, minor correction
Window effect in the power spectrum analysis of a galaxy redshift survey
We investigate the effect of the window function on the multipole power
spectrum in two different ways. First, we consider the convolved power spectrum
including the window effect, which is obtained by following the familiar (FKP)
method developed by Feldman, Kaiser and Peacock. We show how the convolved
multipole power spectrum is related to the original power spectrum, using the
multipole moments of the window function. Second, we investigate the
deconvolved power spectrum, which is obtained by using the Fourier
deconvolution theorem. In the second approach, we measure the multipole power
spectrum deconvolved from the window effect. We demonstrate how to deal with
the window effect in these two approaches, applying them to the Sloan Digital
Sky Survey (SDSS) luminous red galaxy (LRG) sample.Comment: 22 pages, 11 figures, references adde
