Indirect search for supersymmetry in rare B decays

QCD corrections to the gluino induced contribution to b --> s gamma are shown to be important in order to extract reliable bounds on the off-diagonal elements of the squark mass matrices.Comment: 4 pages including 2 postscript figure

When Did You Stop Singing?: Elementary Boys\u27 Attitudes and Self-Efficacy Toward the Act of Singing

The “missing males” epidemic is one which has baffled music educators and researchers for decades. Many research studies have been conducted to explore why boys choose to not be involved in choral ensembles at their middle and high schools. These studies list numerous retention/recruitment strategies; however, the problem remains. Many boys decide before they reach middle school whether they like to sing. The purposes of this study are to examine elementary age boys’ attitudes toward singing and determine at what grade level, if any, there is a significant difference in boys’ attitudes, to search for a relationship between boys’ attitudes and self-efficacy toward the act of singing, and to try to pinpoint reasons and factors contributing to boys’ declining interest in singing at a young age.

A Little Higgs Model with Exact Dark Matter Parity

Based on a recent idea by Krohn and Yavin, we construct a little Higgs model with an internal parity that is not broken by anomalous Wess-Zumino-Witten terms. The model is a modification of the "minimal moose" models by Arkani-Hamed et al. and Cheng and Low. The new parity prevents large corrections to oblique electroweak parameters and leads to a viable dark matter candidate. It is shown how the complete Standard Model particle content, including quarks and leptons together with their Yukawa couplings, can be implemented. Successful electroweak symmetry breaking and consistency with electroweak precision constraints is achieved for natural paramters choices. A rich spectrum of new particles is predicted at the TeV scale, some of which have sizable production cross sections and striking decay signatures at the LHC.Comment: 25 pp. LaTeX; v2: improved discussion of precision constraints and references added; v3: summary of model structure added at beginning of sect. 2, version published in JHEP; v4: small correction in Fig.5; v5: correction to Fig.
