A flexible strain gauge is an essential component in advanced human-machine interfacing, especially when it comes to many important mobile and biomedical appliances that require the detection of finger touches. In this paper, we report one such strain gauge made from a strip of nanoparticle monolayer onto a flexible substrate. This proposed gauge operates on the observation that there is a line...

We consider an extension of the standard electroweak theory with gauge group SU(2)L × SU(2)R × U(1)Ỹ , where the gauge bosons of the extra SU(2)R factor do not couple to ordinary fermions. We show that precision electroweak data and flavour physics provide quite stringent indirect constraints on its parameter space, but still allow for relatively light non-standard gauge and Higgs bosons. We th...

We address in a recent gauge model of unparticles the issues that are important for consistency of a gauge theory, i.e., unitarity and Ward identity of physical amplitudes. We find that non-integrable singularities arise in physical quantities like cross section and decay rate from gauge interactions of unparticles. We also show that Ward identity is violated due to the lack of a dispersion rel...

We report on recent developments and results from Lattice Gauge Theory. These include determinations of the strong coupling constant αs and the b-quark mass Mb and an update on the Kaon B parameter BK . Lattice results for heavy meson decay constants and semileptonic B and D meson decay form factors are reviewed. The first attempts to study the Isgur-Wise function and the radiative Penguin deca...

Results of the chiral quark models for the soft matrix elements involving pions and photons, relevant for high-energy processes, are reviewed. We discuss quantities related to the generalized parton distributions of the pion: the parton distribution functions, the parton distribution amplitudes, and the generalized form factors. The model predictions are compared to the data or lattice simulati...

This review focuses on the discussion of three key results of nucleon structure calculations on the lattice. These three results are the quark contribution to the nucleon spin, Jq, the nucleon-∆ transition form factors, and the nucleon axial coupling, gA. The importance for phenomenology and experiment is discussed and the requirements for future simulations are pointed out. Preprint number: DE...

Semileptonic decays of heavy mesons into light hadrons such as, B → π lν or B → ρ lν, involve hadrons with sizeable momenta, once one moves away from the zero-recoil point at q ≡ (p − p) = q max. “pμ” is the momentum of the decaying heavy meson and “pμ” that of the light daughter meson. High momenta introduce both noise and ap discretization errors into lattice simulations making calculations o...

Propagators of the diagonal and the off-diagonal gluons are studied numerically in the Maximal Abelian gauge of SU(2) lattice gauge theory. We have found a strong enhancement of the diagonal gluons in the infrared region. The enhancement factor is about 50 at our smallest momentum 325 MeV. We have also applied various fits to the propagator formfactors.
