'Ghost particles' could improve understanding the universe
Ghost particles understanding universe
2017/2/16
Trillions of neutrinos, or ghost particles, are passing through us every second. While scientists know this fact, they don’t know what role neutrinos play in the universe because they are devilishly h...
Ghost Force Influence of A Qusicontinuum Method in Two Dimension
Ghost Force Influence A Qusicontinuum Method Two Dimension
2012/8/7
The error caused by the ghost force is studied for a quasicontinuum method with planar interface in two dimension. For a special case, we derive an analytical expression of the error, which is exploit...
The Ghost length, levels and shriek maps on classifying spaces
Level ghost length Gorenstein space shriek map
2012/4/17
We give a lower bound of the cochain type level of the diagonal map on the classifying space of a Lie group by using the ghostness of a shriek map. Moreover, in a derived category, we discuss the triv...
Ambient beam motion and its excitation by ghost lines in the Tevatron
Ambient beam motion its excitation ghost lines Tevatron
2012/2/28
Transverse betatron motion of the Tevatron proton beam is measured and analyzed. It is shown that the motion is coherent and excited by external sources of unknown origins. Observations of the time-va...
Dark matter may be invisible gravitational ghost images and not the real matter imagined

2011/9/25
According to the polar effect in the hyperspherical universe, we realize that “Dark matter” may be invisible gravitational ghost images originating from the matter around the poles and not the real na...

Abstract: In order to estimate in absolute terms the luminosity of LHC certain beam parameters have to be measured very accurately. In particular the total beam current and the relative distribution o...
The inverse-Compton ghost HDF 130 and the giant radio galaxy 6C 0905+3955: matching an analytic model for double radio source evolution
galaxies: individual: RGJ123617/HDF130, 6C0905+3955 – galaxies: evolution – galaxies: jets – radio continuum: galaxies – X-rays: galaxies.
2011/9/28
We present new GMRT observations of HDF 130, an inverse-Compton (IC) ghost of a giant radio source that is no longer being powered by jets. We compare the properties of HDF 130 with the new and import...
Nonperturbative gluon and ghost propagators in d=3
Nonperturbative gluon ghost propagators
2010/12/27
We study the nonperturbative gluon and ghost propagators in d=3 Yang-Mills, using the Schwinger-Dyson equations of the pinch technique. The use of the Schwinger mechanism leads to the dynamical genera...

We present results for a numerical study of the ghost propagator in Coulomb gauge whereby lattice results for the spatial gluon propagator are used as input to solving the ghost Dyson-Schwinger equat...

We study a phenomenological dark energy model which is rooted in the Veneziano ghost of QCD. In this dark energy model, the energy density of dark energy is proportional to Hubble parameter and the pr...
Hindrance of the excitation of the Hoyle state and the ghost of the $2^+_2$ state in $^{12}$C
Hindrance excitation Hoyle state ghost $2^+_2$ state $^{12}$C
2010/12/27
While the Hoyle state (the isoscalar $0^+_2$ excitation at 7.65 MeV in $^{12}$C) has been observed in almost all the electron and $\alpha$ inelastic scattering experiments, the second $2^+$ excited s...
