Loop Model with Generalized Fugacity in Three Dimensions

A statistical model of loops on the three-dimensional lattice is proposed and is investigated. It is O(n)-type but has loop fugacity that depends on global three-dimensional shapes of loops in a particular fashion. It is shown that, despite this non-locality and the dimensionality, a layer-to-layer transfer matrix can be constructed as a product of local vertex weights for infinitely many point...

Three-dimensional model for slipped loop RNA.

Earlier a three-dimensional model for a new unusual DNA conformation referred to as Slipped Loop Structure (SLS) has been suggested by us (1). The same type of folding could occur with RNA as well which means that one must use the A-form of the double helix rather than the B-one. The present paper discusses the creation of an all-atom stereochemically sound model for SLS-RNA. This calculated mo...

Origins of Neutrino Events with Three Muons*

The experimental observation of events in neutrino scattering with three outgoing muons presents a potential challenge to SU2 x U1 gauge models, depending on the source of such events. In this paper a comprehensive study is reported of four possible modes of trimuon production (hadronic, mixed, leptonic and trident modes). Background sources are expected to be significant and will have to be se...

Two-loop neutrino masses and the solar neutrino problem.

The addition of m singlet right-handed neutrinos to the Standard Model leads to radiatively generated mass corrections for the SU(2)L doublet neutrinos. For those neutrinos which are massless at the tree level after this addition, this implies a small mass generated at the two-loop level via W exchange. We calculate these mass corrections exactly by obtaining an analytic form for the general ca...
