Noun1.charm quark- a quark with an electric charge of +2/3 and a mass 2900 times that of an electron and a charm of +1 quark- (physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come ...
In the framework of an extended Nambu鈥揓ona-Lasinio model we study pion condensation in quark matter with an asymmetric isospin composition. We treat this against the gravitational field of a static Einstein universe at finite temperature and chemical potential. This particular choice of the ...
The latter transition may be induced by a relatively small change in compound composition (cf. the behavior of La2 − xSrxO4 or YBa2Cu3O7 − x as a function of x). It is quite interesting to note that oxides such as YBa2Cu3O7 − x may be synthesized in either insulating (x ...
Currently, there is only one experimental candidate for an open-charm state, the recently discovered isoscalar axialvector Tcc+ with a mass of ∼3875MeV and a leading decay channel compatible with an inner composition of DD∗ [5, 34]. Within error bars, the experimental mass and our mass...

Uncertainties related to the background composition are included in the statistical uncertainty for the signal yield through the use of nuisance parameters in the fit. The exception to this is the uncertainty on the Λ0b → N ∗µ−νµ mass shapes due to the limited knowledge of the ...
By comparing this spectrum to contemporary lattice QCD results at three lattice volumes, we analyse the eigenvectors of the Hamiltonian to gain insight into the structure and composition of these two low-lying resonances. We find that an interpretation of the two low-lying nucleon resonances as ...
For resonances, X˜ i is still related to the squared wave function of the channel i, in a phase prescription that automatically renders the wave function real for bound states, and so it can be used as a measure of the weight of that meson-baryon channel in the composition of the ...
After calculation of the composition, we find that the color singlet channel of Σcπ is the main component with the percentage of 90.6%, while the hidden color channel of Λcω and the color singlet channel of ND are the minor components, accounting for 6.2% and 2.2%, respectively. ...
