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...
We investigate the role of trapped neutrinos on the composition of protoneutron stars with quark-hadron phase transitions. Trapped neutrinos shift the transition to higher baryon densities and also reduce the extent of a mixed phase in comparison to neutrino-free matter. Thus, a mixed phase of ba...
Noun1.down quark- a stable quark with an electric charge of -1/3 and a mass 607 times that of an electron 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 pairs; each ...
Nowadays, it has become a common phenomenon to explore the inner core of NSs assuming that it is composed of deconfined quark matter taking into account the clear mass-radius window imposed by the data from the Neutron Star Interior Composition Explorer (NICER) [4,5,6] and the gravitational...
The corresponding phase diagram for the transition from the hadrons to a quark-gluon plasma is discussed and we also describe the composition of the hadron gas for several temperatures and baryon densities.doi:10.1007/BF01650442A. Nyffeler
The effects of internal quark structure of baryons on the composition and structure of neutron star matter with hyperons are investigated in the quark-meso... S Pal,M Hanauske,I Zakout,... - arXiv 被引量: 99发表: 1999年 Quark deconfinement in neutron star cores We show that the modifie...
This is performed using proton–proton collision data from the LHCb detector, corresponding to 2.0 fb−1 of integrated luminosity collected at a centre-of-mass energy of 8 TeV . The b→ u transition, , has not been considered before as Λb0 baryons are not produced at an e+e−...
So it is feasible and meaningful to extend this model to investigate the charmed baryons. In this work, we explore the pentaquark interpretation of charmed baryons in QDCSM. Both qqq − q¯c and qqc − q¯q structures, as well as the coupling of these two structures are taken ...
(4.286), (4.288), (4.289) and (4.290) for baryons in Case III, as done for mesons in Eqs. (4.274), (4.275) and (4.282). 6. Check that the thermodynamic identity, ε = Ts + μn − P, is satisfied for the cases studied in this chapter: (a) the quark-gluon plasma with ...
The exclusive $^{2}mathrm{H}$(e,e'p)${mathit{N}}^{mathrm{*}}$ process at CEBAF energies, with the missing mass coincidence technique, offers the opportunity to reveal the baryon-baryon (BB) composition of the deuteron and to reconstruct the deuteron six-quark wave function. As an exa...
