A solution to the mu problem in the supersymmetric unparticle physics
Tatsuru Kikuchi
Recently, conceptually new physics beyond the Standard Model has been proposed by Georgi, where a new physics sector becomes conformal and provides "unparticle" which couples to th…

Dark Matter Model Selection and the ATIC/PPB-BETS anomaly
Chuan-Ren Chen, Koichi Hamaguchi, Mihoko M. Nojiri +2
We argue that we may be able to sort out dark matter models in which electrons are generated through the annihilation and/or decay of dark matter, by using a fact that the initial…

Subjet distributions were measured in neutral current deep inelastic ep scattering with the ZEUS detector at HERA using an integrated luminosity of 81.7 pb-1. Jets were identified…
Vector Supersymmetry: Casimir operators and contraction from OSp(3,2|2)
Roberto Casalbuoni, Federico Elmetti, Joaquim Gomis +3
We study some algebraic properties of the 'vector supersymmetry' (VSUSY) algebra, a graded extension of the four-dimensional Poincare' algebra with two odd generators, a vector and…
Heavy Quark Effects in the Virtual Photon Structure Functions
Yoshio Kitadono, Ken Sasaki, Takahiro Ueda +1
We investigate the heavy quark mass effects in the virtual photon structure functions and in the framework of the mass-independent ren…
Evidence of the Θ^+ in the γd \to K^+K^-pn reaction
T. Nakano, N. Muramatsu, D. S. Ahn +53
The γd \to K^+K^-pn reaction has been studied to search for the evidence of the Θ^+ by detecting K^+K^- pairs at forward angles. The Fermi-motion corrected nK^+ invariant mass dist…
