Moreover, several reasons like strong magnetic field [17], phase transitions [18], pion condensation [19], the presence of a type 3A superfluid [20], mixture of two fluids etc. may cause for anisotropy in compact stars. Recently, a lot of research work on anisotropic stellar configuration ...
This particular choice of the gravitational field configuration enables us to investigate phase transitions of the system with exact consideration of the role of this field in the formation of quark and pion condensates. Also, we point out its influence on the phase portraits. We demonstrate the ...
摘要: Nuclear magnetic moments are investigated in the relativistic quark shell model. The importance of clustering effects, induced by configuration mixing in the j-j coupling quark shell model, is pointed out.关键词: Electromagnetic moments
KG Chetyrkin,A Maier - 《Journal of High Energy Physics》 被引量: 33发表: 2010年 Diquark mass differences from unquenched lattice QCD we calculate diquark correlation functions in the landau gauge on the lattice using overlap valence quarks and 2+1-flavor domain wall fermion configuration......
9.Specifically, a photon with sufficient energy can be converted into what's called a J/ψ meson, composed of a charm quark and charm antiquark through a process that's sensitive to the configuration of gluons in any nearby protons. 10.Scientists at the Large Hadron Collider have announced ...
exchange of a pion orρmeson23, similar to electromagnetic van der Waals forces attracting electrically neutral atoms and molecules. These states are expected to have a spatial extension significantly larger than a typical compact hadron. Conversely, the only hadron currently observed that contains a ...
The effects of SU(3) symmetry breaking and configuration mixing have been investigated for the weak vector and axial-vector form factors in the chiral constituent quark model ( χ CQM ) for the strangeness changing as well as strangeness conserving semileptonic octet baryon decays in the nonpertur...
Using chiQM with configuration mixing, the contribution of the gluon polarization to the flavor singlet component of the total spin has been calculated phe... H Dahiya,M Gupta - 《International Journal of Modern Physics A》 被引量: 29发表: 2003年 ...
With the recently obtained vacuum configuration of the bilocal field, we have calculated the decay constant f(sigma) of sigma-meson in a quantum chromodynamics-based model field theory. From investigating the calculated result, it can be seen that the obtained value of f(sigma) is quite reasona...
Bremsstrahlung emission in the decay of particles is simulated using the PHotos software in the default configuration89, which is observed to agree with an independent quantum electrodynamics calculation at the level of 1% (ref. 5). Simulated events are weighted to correct for the imperfect ...
