In a simplified model we study the hadronization of quark matter in an expanding fireball, in particular the approach to a final hadronic composition in equilibrium. Ideal hadron gas equilibrium constrained by conservation laws, the fugacity parametrization, as well as linear and non-linear ...
Why is it easier to see the properties of the c, b, and t quarks in mesons having composition W- or t $\overline{A}$ rather than in baryons having a mixture of quarks, such as udb? Two protons each of mass 1.67x10-27 kg an...

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...
After calculating the composition, we find that the channel of cπ is the main component with the proportion of 90.0%, while the channel of N D and the rest channels are the minor components, accounting for 8.1% and 1.9%, respectively. From Fig. 2 we can see that the energy of this ...
(https://journals.aps.org/prc/abstract/10.1103/PhysRevC.95.042201) research , published in the latest edition of the journal Physical Review C, aims to study a class of particles called hybrid mesons, which are identical to ordinary mesons in composition, but are believed to exhibit drastically...
