Track-before-detect for Infrared Maneuvering Dim Multi-target via MM-PHD
Abstract In this paper, we present a novel and efficient track-before-detect (TBD) algorithm based on multiple-model probability hypothesis density (MM-PHD) for tracking infrared maneuvering dim multi-target. Firstly, the standard sequential Monte...

Higher order corrections to color superconducting gaps
Abstract We find a (nonlocal) gauge where the wavefunction renormalization constant does not get any corrections for all momenta in the hard-dense loop approximation. In this gauge, we solve the Schwinger–Dyson equations for the diquark condensate...

Five adjustable parameter fit of quark and lepton masses and mixings
Abstract We develop a model of ours fitting the quark and lepton masses and mixing angles by removing from the model a Higgs field previously introduced to organise a large atmospheric mixing angle for neutrino oscillations. Due to the off-diagonal...

Collective vibrations built on the Kπ=9− high-spin isomer in 180Ta
Abstract Collective structures in 180Ta built on the meta-stable K π =9− high-spin isomer were investigated using two types of Coulomb excitation experiments. In-beam studies...

New aspects of muon–electron nuclear conversion
Abstract We found a new important tree-level contribution to muon–electron nuclear conversion from neutrino exchange between two quarks in the same nucleon and demonstrated that this process, contrary to common belief, can be observed in the near...

On the renormalization of a bosonized version of the chiral fermion–meson model at finite temperature
Abstract Feynman's functional formulation of statistical mechanics is used to study the renormalizability of the well-known Linear Chiral Sigma Model in the presence of fermionic fields at finite temperature in an alternative way. It is shown that...

Gravitating Yang–Mills vortices in 4+1 spacetime dimensions
Abstract The coupling to gravity in D=5 spacetime dimensions is considered for the particle-like and vortex-type solutions obtained by uplifting the D=4 Yang–Mills instantons and D=3 Yang–Mills–Higgs monopoles. It turns out that the particles become ...

Measurements of scintillation efficiency and pulse shape for low energy recoils in liquid xenon
Abstract Results of observations of low energy nuclear and electron recoil events in liquid xenon scintillator detectors are given. The relative scintillation efficiency for nuclear recoils is 0.22±0.01 in the recoil energy range 40–70 keV. Under...

Baryogenesis from leptogenesis in SO(10) models
Abstract We discuss the baryogenesis via leptogenesis mechanism within the supersymmetric and nonsupersymmetric SO(10) models. We find that the nonsupersymmetric model, endowed with an intermediate scale, is generally favoured, unless some fine...

Realization of global symmetries in the Wilsonian renormalization group
Abstract We present a method to solve the master equation for the Wilsonian action in the antifield formalism. This is based on a representation theory for cutoff-dependent global symmetries along the Wilsonian renormalization group (RG) flow. For...

Notes on Mayer expansions and matrix models
Abstract Mayer cluster expansion is an important tool in statistical physics to evaluate grand canonical partition functions. It has recently been applied to the Nekrasov instanton partition function of N ...

Single-slot-dipole Coupled YBCO Josephson Junctions for Terahertz Wave Detectors
Abstract In this paper, we propose a terahertz wave detector using a grain boundary Josephson junctions (GBJJs) with a single slot-dipole antenna (SDA). A full-wavelength single SDA structure designed for 220GHz was patterned with an Au on an...

Mode-stirred reverberation chambers: A paradigm for spatio-temporal complexity in dynamic electromagnetic environments
Abstract We investigate probability distributions in dynamic multi-mode electromagnetic cavities, commonly referred to as mode-stirred reverberation chambers. We show that Bessel K and Bessel ...

Doppler-spectrally encoded imaging of translational objects
Abstract The image of a translational target is moved by the Doppler-shifted phase of the diffraction field of the light incident on the target. However, no one has yet utilized the physical relationship between the Doppler effect and the...

Quasilocal conservation laws in XXZ spin-1/2 chains: Open, periodic and twisted boundary conditions
Abstract A continuous family of quasilocal exact conservation laws is constructed in the anisotropic Heisenberg (XXZ) spin-1/2 chain for periodic (or twisted) boundary conditions and for a set of commensurate anisotropies densely covering the entire ...
