Could the be substantially different from and in the supersymmetric standard model?

Mike Bisset, Otto C. W. Kong, Cosmin Macesanu +1

R-parity stands as an ad hoc assumption in the most popular version of the supersymmetric standard model. More than fifteen years' studies of R-parity violations have been restrict…

Bending and Base-Stacking Interactions in Double-Stranded Semiflexible Polymer

Zhou Haijun, Ou-Yang Zhong-can

Simple expressions for the bending and the base-stacking energy of double-stranded semiflexible biopolymers (such as DNA and actin) are derived. The distribution of the folding ang…

Supersymmetry without R-parity : Constraints from Leptonic Phenomenology

M. Bisset, O. C. W. Kong, C. Macesanu +1

R-parity conservation is an {\it ad hoc} assumption in the most popular version of the supersymmetric standard model. Most studies of models which do allow for R-parity violation h…
