We propose a new mechanism toward the solution to the doublet-triplet Higgs mass splitting problem in the supersymmetric grand unified theory. Our model is based on the gauge group SU(5)H × SU(5)GUT , where SU(5)H and SU(5)GUT are new strong gauge interaction and the ordinary grand unified gauge group, respectively. The doublet-triplet Higgs mass splitting is realized through the quantum deform...

We investigate the collective coordinate quantization of the icosahedrally symmetric B = 7 Skyrmion, which is known to have a ground state with spin 7 2 and isospin 1 2 . We find a particular quantum state maximally preserving the symmetries of the classical solution, and also present a novel relationship between the quantum state and the rational map approximation to the classical solution. We...

We study the one-loop radiative corrections to the SU(2) breaking mass splittings between sfermions in SU(2) doublets in the Minimal Supersymmetric Standard Model. At tree-level, the differences of mass squared m f̃1L −m f̃2L of SU(2) doublet sfermions (f̃1, f̃2)L in the first two generations are determined by tanβ, and are universal to sleptons and squarks. The radiative correction, however, break...

Quantum mechanics abounds in models with Hamiltonian operators which are energy-dependent. A linearization of the underlying Schrödinger equation with H = H(E) is proposed here via an introduction of a doublet of separate energyindependent representatives K and L of the respective right and left action of H(E). Both these new operators are non-Hermitian so that our formalism admits a natural ex...

We study the effect of Bπ continuum in the QCD sum rule analysis of the heavy meson doublet (0+, 1+) in the leading order of heavy quark effective theory. New sum rules are derived for the leading order binding energy Λ̄+, 1 2 and pionic coupling constant g′. PACS number: 12.39.Hg, 11.30.Rd, 13.20.He, 12.38.Lg

A comparative study is given between two micro-mechanical models that have been developed to simulate the behavior of cemented particulate materials. The first model is a discrete analytical approach called doublet mechanics that represents a solid as an array of particles. This scheme develops analytical expressions for the micro-deformation and stress fields between particle pairs (a doublet)...

The addition of an extra stimulus pulse, or doublet, at the beginning of a low-frequency train has been shown to substantially increase isometric force. This study examined the effects of muscle movement on this doublet potentiation. The soleus muscles of anesthetized cats were stimulated at 10 Hz for 1 s, with and without an added doublet (0.01-s interval). Isovelocity releases reduced but did...
